Instances of crystal structures that remain isomorphous in spite of some minor changes in their respective mol­ecules, such as change in a substituent atom/group, can provide insights into the factors that govern crystal packing. In this context, an accurate description of the crystal structures of an isomorphous pair that differ from each other only by a chlorine–methyl substituent, viz. 5′′-(2-chloro­benzyl­idene)-4′-(2-chloro­phen­yl)-1′-methyl­dispiro­[acenaphthene-1,2′-pyrrolidine-3′,3′′-piperidine]-2,4′′-dione, C34H28Cl2N2O2, (I), and its analogue 1′-methyl-5′′-(2-methyl­benzyl­idene)-4′-(2-methyl­phen­yl)di­spiro­[acenaphthene-1,2′-pyrrolidine-3′,3′′-piperidine]-2,4′′-dione, C36H34N2O2, (II), is presented. While there are two C—H⋯O weak inter­molecular inter­actions present in both (I) and (II), the change of substituent from chlorine to methyl has given rise to an additional weak C—H⋯O inter­molecular inter­action that is relatively stronger than the other two. However, the presence of the stronger C—H⋯O inter­action in (II) has not disrupted the validity of the chloro-methyl exchange rule. Details of the crystal structures and Hirshfeld analyses of the two compounds are presented.

1. Chemical context

The prediction of crystal structures has emerged as an exciting field involving researchers from diverse fields primarily because of its challenging complexity, which is considered analogous to that of the protein-folding problem. Attempts made in the field of crystal-structure prediction, its present status and the challenges ahead were discussed in detail in a recent article (Oganov, 2018[Oganov, A. R. (2018). Faraday Discuss. 211, 643-660.]). In this context, instances of crystal structures that remain isomorphous in spite of some minor changes in their respective mol­ecules, such as a change in a substituent atom/group, are worthy of study as they might provide some insights regarding the subtle factors that govern the crystal packing.

[Scheme 1]

The title compounds (I)[link] and (II)[link] are good examples of crystal structures that obey the Cl–Me exchange rule, complying with the general conclusions arrived at in earlier studies (Jones et al., 1981[Jones, W., Ramdas, S., Theocharis, C. R., Thomas, J. M. & Thomas, N. W. (1981). J. Phys. Chem. 85, 2594-2597.]; Gnanaguru et al., 1984[Gnanaguru, K., Murthy, G. S., Venkatesan, K. & Ramamurthy, V. (1984). Chem. Phys. Lett. 109, 255-258.]; Desiraju & Sarma, 1986[Desiraju, G. R. & Sarma, J. A. R. P. (1986). Proc. - Indian Acad. Sci. Chem. Sci. 96, 599-605.]). In some recent studies carried out in our laboratory on mol­ecules that showcase the validity of the Cl–Me exchange rule, it has been observed that factors such as the presence of disorder and minor conformational differences have not disturbed the tendency of mol­ecules to remain as isomorphous pairs (Rajni Swamy, et al., 2013[Rajni Swamy, V., Müller, P., Srinivasan, N., Perumal, S. & Krishnakumar, R. V. (2013). Acta Cryst. C69, 412-415.]; Sribala et al., 2018[Sribala, R., Srinivasan, N., Indumathi, S. & Krishnakumar, R. V. (2018). Acta Cryst. E74, 1267-1271.]). Inter­estingly, the validity of the Cl–Me exchange rule has also been observed in some regularly shaped planar mol­ecules (Nath & Nangia, 2012[Nath, N. K. & Nangia, A. (2012). Cryst. Growth Des. 12, 5411-5425.]).

From a pharmacological view point, the title compounds (I)[link] and (II)[link] are spiro compounds that consist of a methyl­pyrrole moiety with its 2- and 3- positions as spiro carbons linked, respectively, to acenapthene and methyl pyridinone ring systems. Each of these ring systems has a variety of associated biological properties. Studies on some 4-pyridone derivatives have shown them to be potent anti­malarial agents (Bueno et al., 2011[Bueno, J. M., Manzano, P., García, M. C., Chicharro, J., Puente, M., Lorenzo, M., García, A., Ferrer, S., Gómez, R. M., Fraile, M. T., Lavandera, J. L., Fiandor, J. M., Vidal, J., Herreros, E. & Gargallo-Viola, D. (2011). Bioorg. Med. Chem. Lett. 21, 5214-5218.]) and effective in the treatment and prophylaxis of the hepatitis B virus infection (Cheng et al., 2018[Cheng, Z., Han, X., Liang, C. & Yang, S. (2018). US Patent Pub. No. US2018/0134705A1.]). Acenaphthene is a pollutant known for its cytotoxicity (Jiang et al., 2019[Jiang, L., Zhang, B., Wang, Y., Sun, J., Ma, X., Wang, G., Fu, S., Lin, C. & Li, Y. (2019). Nat. Prod. Res. https://doi. org/10.1080/14786419.2019.1647422]) but is also useful as a dye inter­mediate. Derivatives of acenaphthene are found to exhibit anti­tumor (El-Ayaan et al., 2007[El-Ayaan, U., Abdel-Aziz, A. A.-M. & Al-Shihry, S. (2007). Eur. J. Med. Chem. 42, 1325-1333.]; Zhu et al., 2008[Zhu, W., Dai, M., Xu, Y. & Qian, X. (2008). Bioorg. Med. Chem. 16, 3255-3260.]) and fungistatic properties (McDavids & Daniels, 1951[McDavids, J. E. & Daniels, T. C. (1951). J. Am. Pharm. Assoc. (Sci. ed.), 40, 325-326.]). Pyrrole derivatives belong to an important class of heterocycles owing to their potential applications as anti­microbial, anti­viral, anti­malarial, anti­tubercular, anti-inflammatory and anti­cancer agents (Gholap, 2016[Gholap, S. S. (2016). Eur. J. Med. Chem. 110, 13-31.]).

2. Structural commentary

The mol­ecular structures of (I)[link] and (II)[link] (Figs. 1[link] and 2[link], respectively) differ from each other only by a chlorine atom in (I)[link] being replaced by a methyl group in (II)[link]. This replacement has not induced any significant change in their unit-cell parameters, lattice type or space group. Similarly, there are no substantial changes in the torsion angles of the title compounds (see Tables 1[link] and 2[link]), as (I)[link] and (II)[link] are isomorphous.

As expected, the conformational features of both compounds are nearly identical, as shown in a overlay diagram (Fig. 3[link]). The five-membered pyrrolo ring (N2/C21/C20/C2/C23) adopts an envelope conformation on N2 with puckering parameters Q(2) = 0.4011 (2) Å and φ = 180.3733 (3)° for (I)[link], which are comparable with the values of Q(2) = 0.4047 (2) Å and φ = 180.3444 (3)° for (II)[link]. In both of the structures, the six-membered pyridinone ring (N1/C3/C2/C1/C6/C5) adopts a screw-boat conformation with puckering parameters Q = 0.5572 (16) Å, θ = 138.9 (2)°, φ = 219.8 (3)° in (I)[link] and Q = 0.5603 (17) Å, θ = 137.7 (2)°, φ = 219.6 (3)° in (II)[link]. The acenaphthene ring system is planar in both (I)[link] and (II)[link]. However, the O2 atom deviates from the mean plane of the acenaphthene ring system by 0.289 (2) Å in (I)[link] and 0.311 (2) Å in (II)[link], with the r.m.s. deviation of the fitted atoms being 0.043 and 0.044, respectively. This deviation is presumably due to the fact that the O2 atom is involved in two weak C—H⋯O inter­actions that are characteristic of the mol­ecular inter­action patterns of both (I)[link] and (II)[link].

[Figure 3]
Figure 3
An overlay diagram depicting the superimposition of mol­ecule (I)[link] and (II)[link] showing no differences in the conformations.

The dihedral angle between the mean planes of the two chloro­phenyl groups in (I)[link] is 67.66 (9)°, similarly the corresponding angle between the two methyl­phenyl groups in (II)[link] is 66.78 (11)°. The dihedral angles between the acenaphthene ring system and the chloro­phenyl groups are 69.1 (1) and 49.4 (1)°, respectively. The corresponding angles in the methyl-substituted analogue are 72.3 (1) and 47.8 (1)°, respectively. Thus, it is clear that the minor differences observed in the conformation of the mol­ecules are insufficient to disrupt the tendency of these mol­ecules to remain isomorphous.

3. Supra­molecular features

There are no classical hydrogen bonds in the structures of either (I)[link] or (II)[link]. However, in both structures two weak C—H⋯O-type inter­molecular inter­actions, viz. C10—H10⋯O2 and C16—H16⋯O2, which are identical in nature and characteristic of similar fundamental mol­ecular inter­action patterns are present (Tables 3[link] and 4[link]). The C16—H16⋯O2 inter­action occurs between centrosymmetric pairs (Fig. 4[link]), leading to the formation of R22(20) graph-set motifs along the b-axis direction in both (I)[link] and (II)[link]. Similarly, in both (I)[link] and (II)[link] the C10—H10⋯O2 inter­action links glide-related mol­ecules along the b-axis direction (Fig. 5[link]). The mol­ecular aggregation pattern may be visualized as being composed of these two characteristic weak inter­actions in such a manner that centrosymmetric dimeric pairs are linked through glide-related chains of mol­ecules, forming a two-dimensional layer parallel to the bc plane in both structures, as shown in Figs. 6[link] and 7[link], respectively.

In (II)[link], an additional inter­molecular inter­action is observed, viz. C36—H36A⋯O1, that is stronger than the two characteristic weak inter­molecular inter­actions and involves the replaced substituent methyl group (C36—H36A) as a donor and the piperidinone O1 atom as an acceptor (see Table 4[link]). It may be concluded that the presence of this additional C—H⋯O inter­action in (II)[link] has not disrupted the validity of the chloro–methyl exchange rule.

In addition, a weak C—H⋯π inter­action involving different donor groups and acceptor π-ring systems is present in both (I)[link] and (II)[link]. The C5—H5B⋯π inter­action observed in (I)[link] is between the C5 atom of the methyl­piperidinone ring as a donor and the C25—C29/C34 ring of the acenaphthenone system as an acceptor. Inter­estingly, a geometrically identical weak π–π inter­action about an inversion centre is observed with centroid–centroid Cg3⋯Cg3(1 − x, 2 − y, −z) distances of 3.7459 (2) Å in (I)[link] and 3.8351 (2) Å in (II)[link] with respective slippages of 1.250 and 1.367 Å where Cg3 is the centroid of the C14–C19 ring. The shortest Cl⋯Cl distance observed [Cl1 ⋯Cl1(−x + 1, −y + 2, −z + 1)] is 4.088 (1) Å and bears no structural significance.

4. Database survey

A thorough search in the Cambridge Structural Database (CSD Version 5.39, update Nov 2017; Groom et al., 2016[Groom, C. R., Bruno, I. J., Lightfoot, M. P. & Ward, S. C. (2016). Acta Cryst. B72, 171-179.]) using the main skeleton of the title compounds (having 3D coordinates with no disorder, no ions and no other errors with R factors less than 0.05) gave only three hits: 5′′-(4-chloro­benzyl­idene)-4′-(4-chloro­phen­yl)-1′,1′′-dimethyl-2H,4′′H-di­spiro­[ace­naphthyl­ene-1,2′-pyrrolidine-3′,3′′-piperidine]-2,4′′-dione (YIRKUG; Pandiarajan et al., 2008[Pandiarajan, S., Saravanamoorthy, S. N., Kumar, B. R., Kumar, R. R. & Athimoolam, S. (2008). Acta Cryst. E64, o99-o100.]), 5′′-benzyl­idene-1′,1′′-dimethyl-4′-phenyl-acenapthene-2-spiro-2′-pyrrolidine-3′-spiro-3′′-piperidine-1,4′′-dione (MAJHEL; Aravindan et al., 2004[Aravindan, P. G., Selvanayagam, S., Velmurugan, D., Ravikumar, K., Sridhar, G. & Raghunathan, R. (2004). Acta Cryst. E60, o2149-o2151.]) and 1-methyl-4-(4-methyl­phen­yl)pyrrolo-(spiro­[2.2′′]acenaphthene-1′′-one)-spiro-[3.3′]-(spiro-[5′.5′′′]-3′′′-(4-chloro­phen­yl)-4′′′-(4-methyl­phen­yl)-isoxazoline)-1′-methyl­tetra­hydro-4′(1H)-pyridinone (XUQFOF; Kumar, et al., 2009[Kumar, R. R., Loganayaki, B. & Perumal, S. (2009). Synth. Commun. 39, 3197-3216.]).

5. Hirshfeld surface analysis

Hirshfeld surface (HS) analysis was used to investigate and visualize the weak inter­molecular inter­actions influential in the packing of the mol­ecules in the crystal. The visual representation of mol­ecular inter­actions on this isosurface is determined using two parameters, viz. di and de , which represent the distances from a given point on the surface to the nearest atom inside and outside the surface, respectively. The normalized contact distance, dnorm is based on the values of di and de.

In the present work, the Hirshfeld surfaces (Spackman & Jayatilaka, 2009[Spackman, M. A. & Jayatilaka, D. (2009). CrystEngComm, 11, 19-32.]) and the associated two-dimensional fingerprint plots for title compounds (I)[link] and (II)[link] were generated using CrystalExplorer3.0 (Wolff et al., 2012[Wolff, S. K., Grimwood, D. J., McKinnon, J. J., Turner, M. J., Jayatilaka, D. & Spackman, M. A. (2012). Crystal Explorer, University of Western Australia.]). The Hirshfeld surfaces mapped over dnorm together with decomposed finger print plots (McKinnon et al., 2007[McKinnon, J. J., Jayatilaka, D. & Spackman, M. A. (2007). Chem. Commun. pp. 3814-3816.]; Tan et al., 2019[Tan, S. L., Jotani, M. M. & Tiekink, E. R. T. (2019). Acta Cryst. E75, 308-318.]) for (I)[link] and (II)[link] are presented in Figs. 8[link] and 9[link], respectively. Being isomorphic and isostructural in nature, both (I)[link] and (II)[link] display similar C—H⋯O inter­molecular inter­actions. The combined O⋯H and H⋯O inter­actions appear symmetrically as distinct spikes at the bottom of the fingerprint plot and contribute 7.5 and 6.9%, respectively, of the total surface in compounds (I)[link] and (II)[link].

[Figure 8]

[Figure 9]
Figure 9
Hirshfeld surface of (II)[link] mapped over shape-index and dnorm and decomposed fingerprint plots of the dominant inter­actions.

The symmetrical inter­nal wing-like projections correspond to C⋯H/H⋯C contacts, which account for 16% of the HS in (I)[link] and 19.1% in (II)[link]. The dominant contribution is from the H⋯H contacts [56.3% in (I)[link] and 70.2% in (II)], as shown by the area occupied between the spikes. Such prominent differences may be accounted for by the presence of a Cl⋯H/H⋯Cl contact in (I)[link] (11.3% contribution) and its absence in (II)[link].

6. Synthesis and crystallization

For (I)[link], a mixture of 1-methyl-3,5-bis­[(E)-2-chloro­phenyl­methyl­idene] tetra­hydro-4(1H)- pyridinone (1 mmol), acenaphthene­quinone (1 mmol) and sarcosine (1 mmol) was dissolved in methanol (15 mL) and refluxed for 30 min. After completion of the reaction, as evident from TLC, the mixture was poured into water (50 mL) and the precipitated solid was filtered and washed with water (100 mL) to obtain pure (I)[link] as a yellow solid, (0.31 g, 98%), mp 448–449 K, Rf (petroleum ether/EtOAc, 4:1) 0.40. Suitable crystals for single-crystal X-ray studies were obtained by recrystallization of the product from ethanol.

A similar procedure for (II)[link] was adopted by dissolving a mixture of 1-methyl-3,5-bis­[(E)-2-methyl­phenyl­methyl­idene] tetra­hydro-4(1H)-pyridinone (1 mmol), acenaphthene­quinone (1 mmol) and sarcosine (1 mmol) in methanol (15 mL) to yield yellow crystals.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 5[link]. C-bound H atoms were included in calculated positions and treated as riding, with C—H = 0.95–1.00 Å and Uiso(H) = 1.5Ueq(C) for methyl H atoms or 1.2Ueq(C) otherwise. The H atoms of the methyl atoms C35 and C36 in (II)[link] were refined as idealized and disordered over two positions since significant residual electron densities were noticed between the three hydrogen atoms of the respective methyl C atoms. The introduction of a disordered model for these two methyl groups had appreciable impact on the final structural parameters.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
