The asymmetric units of the title compounds both contain one nonplanar mol­ecule. In 4-benzyl-6-phenyl-4,5-di­hydro­pyridazin-3(2H)-one, C17H14N2O, (I), the phenyl and pyridazine rings are twisted with respect to each other, making a dihedral angle of 46.69 (9)°; the phenyl ring of the benzyl group is nearly perpendicular to the plane of the pyridazine ring, the dihedral angle being 78.31 (10)°. In methyl 2-[5-(2,6-di­chloro­benz­yl)-6-oxo-3-phenyl-1,4,5,6-tetra­hydropyridazin-1-yl]acetate, C20H16Cl2N2O3, (II), the phenyl and pyridazine rings are twisted with respect to each other, making a dihedral angle of 21.76 (18)°, whereas the phenyl ring of the di­chloro­benzyl group is inclined to the pyridazine ring by 79.61 (19)°. In the crystal structure of (I), pairs of N—H⋯O hydrogen bonds link the mol­ecules into inversion dimers with an R22(8) ring motif. In the crystal structure of (II), C—H⋯O hydrogen bonds generate dimers with R12(7), R22(16) and R22(18) ring motifs. The Hirshfeld surface analyses of compound (I) suggests that the most significant contributions to the crystal packing are by H⋯H (48.2%), C⋯H/H⋯C (29.9%) and O⋯H/H⋯O (8.9%) contacts. For compound (II), H⋯H (34.4%), C⋯H/H⋯C (21.3%) and O⋯H/H⋯O (16.5%) inter­actions are the most important contributions.

1. Chemical context

Pyridazines are an important family of six-membered aromatic heterocycles (Akhtar et al., 2016[Akhtar, W., Shaquiquzzaman, M., Akhter, M., Verma, G., Khan, M. F. & Alam, M. M. (2016). Eur. J. Med. Chem. 123, 256-281.]). The chemistry of pyridazinones has been an inter­esting field of research for decades and this nitro­gen-containing heterocycle has become a scaffold of choice for the development of potential drug candidates (Dubey & Bhosle, 2015[Dubey, S. & Bhosle, P. A. (2015). Med. Chem. Res. 24, 3579-3598.]). Pyridazinone is an important pharmacophore possessing a wide range of biological applications (Asif, 2014[Asif, M. (2014). Mini-Rev. Med. Chem. 14, 1093-1103.]). A review of the literature revealed that substituted pyridazinones have received a lot of attention in recent years because of their significant potential as anti­microbial (Sönmez et al., 2006[Sönmez, M., Berber, I. & Akbaş, E. (2006). Eur. J. Med. Chem. 41, 101-105.]), anti­hypertensive (Siddiqui et al., 2011[Siddiqui, A. A., Mishra, R., Shaharyar, M., Husain, A., Rashid, M. & Pal, P. (2011). Bioorg. Med. Chem. Lett. 21, 1023-1026.]), anti­depressant (Boukharsa et al., 2016[Boukharsa, Y., Meddah, B., Tiendrebeogo, R. Y., Ibrahimi, A., Taoufik, J., Cherrah, Y., Benomar, A., Faouzi, M. E. A. & Ansar, M. (2016). Med. Chem. Res. 25, 494-500.]), anti-HIV (Livermore et al., 1993[Livermore, D., Bethell, R. C., Cammack, N., Hancock, A. P., Hann, M. M., Green, D., Lamont, R. B., Noble, S. A., Orr, D. C. & Payne, J. J. (1993). J. Med. Chem. 36, 3784-3794.]) and anti-inflammatory (Barberot et al., 2018[Barberot, C., Moniot, A., Allart-Simon, I., Malleret, L., Yegorova, T., Laronze-Cochard, M., Bentaher, A., Médebielle, M., Bouillon, J. P., Hénon, E., SAPI, J., Velard, F. & Gérard, S. (2018). Eur. J. Med. Chem. 146, 139-146.]) agents.

We report herein the syntheses and crystal and mol­ecular structures of the pyridazinone derivatives 4-benzyl-6-phenyl-4,5-di­hydro­pyridazin-3(2H)-one, (I), and methyl 2-[5-(2,6-di­chloro­benz­yl)-6-oxo-3-phenyl-1,4,5,6-tetra­hydropyridazin-1-yl]acetate, (II), as well as the analyses of their Hirshfeld surfaces.

2. Structural commentary

The mol­ecular structures of compounds (I) and (II) are illustrated in Figs. 1[link] and 2[link], respectively. The common moiety for (I) and (II) is 4-benzyl-6-phenyl-4,5-di­hydro­pyridazin-3(2H)-one. The differences between (I) and (II) pertain to the addition of two chloro groups at the C2 and C6 ring positions of the benzyl group and N-alkyl­ation of pyridazinone at the 2-position with an ethyl acetate group for (II). In (I), the phenyl ring (atoms C12–C17) and the pyridazine ring (N1/N2/C11/C10/C2/C1) are twisted with respect to each other, making a dihedral angle of 46.69 (9)°; the phenyl ring of the benzyl group (C4–C9) is nearly perpendicular to the pyridazine ring, with a dihedral angle of 78.31 (10)° (Fig. 1[link]). In (II), the phenyl ring (C11–C16) and the pyridazine ring (N1/N2/C17/C8/C9/C10) are twisted with respect to each other, making a dihedral angle of 21.76 (18)°; the phenyl ring (C1–C6) of the benzyl group is inclined to the pyridazine ring by 79.61 (19)°. The meth­oxy group in (II) is disordered over two sets of sites with an occupancy ratio of 0.626 (11):0.374 (11) (Fig. 2[link]). In (I), the carbonyl group has a C1=O1 bond length of 1.243 (2) Å, and the C1—N1 and C11—N2 bond lengths in the pyridazine ring are 1.363 (2) and 1.304 (2) Å, respectively. The corresponding values in (II) are 1.229 (5) Å for C17=O1, 1.388 (5) Å for C17—N2 and 1.299 (4) Å for C10—N1. The N1—N2 bond lengths in the structures are virtually the same, with values of 1.348 (2) Å in (I) and 1.353 (4) Å in (II).

3. Supra­molecular features

In the crystal of (I), mol­ecules are linked by C—H⋯O hydrogen bonds (Table 1[link]) between the methine C10—H10 group and the carbonyl O1 atom of an adjacent mol­ecule (Fig. 3[link]a), and by a pair of N—H⋯O hydrogen bonds forming inversion dimers with an [R_{2}^{2}](8) ring motif (Fig. 3[link]b). The dimers are linked by weak π–π inter­actions, with a centroid-to-centroid distance of 3.957 (2) Å for Cg1 and Cg2, where Cg1 is the centroid of the N1/N2/C11/C10/C2/C1 ring and Cg2 that of the C12–C17 phenyl ring. In this way, a three-dimensional network is formed.

In the crystal of (II), mol­ecules are connected via C—H⋯O hydrogen bonds between aryl groups and the carbonyl O1 atom (Table 2[link]), whereby C9—H9⋯O2i and C12—H12⋯O2i hydrogen bonds generate R12(7) motifs (Fig. 4[link]); likewise, [R_{2}^{2}](16) and [R_{2}^{2}](18) ring motifs are also observed.

4. Database survey

A search of the Cambridge Structural Database (CSD, Version 5.40, update of February 2019; Groom et al., 2016[Groom, C. R., Bruno, I. J., Lightfoot, M. P. & Ward, S. C. (2016). Acta Cryst. B72, 171-179.]) for the 4-benzyl-6-phenyl­pyridazin-3(2H)-one skeleton yielded three hits, namely 4-(2-chloro-6-fluoro­phen­yl)-2,5-dioxo-8-phenyl-1,2,3,4,5,6-hexa­hydro­pyrido[2,3-d]pyridazine (BARQOA; Pita et al., 2000[Pita, B., Sotelo, E., Suárez, M., Raviña, E., Ochoa, E., Verdecia, Y., Novoa, H. N., Blaton, N., de Ranter, C. & Peeters, O. M. (2000). Tetrahedron, 56, 2473-2479.]), 4-(2-chloro-5-nitro­phen­yl)-2,5-dioxo-8-phenyl-1,2,3,4,5,6-hexa­hydro­pyrido[2,3-d]pyridazine (BARQUG; Pita et al., 2000[Pita, B., Sotelo, E., Suárez, M., Raviña, E., Ochoa, E., Verdecia, Y., Novoa, H. N., Blaton, N., de Ranter, C. & Peeters, O. M. (2000). Tetrahedron, 56, 2473-2479.]) and 4-benzyl-6-p-tolyl­pyridazin-3(2H)-one (YOTVIN; Oubair et al., 2009[Oubair, A., Daran, J.-C., Fihi, R., Majidi, L. & Azrour, M. (2009). Acta Cryst. E65, o1350-o1351.]). In YOTVIN, the mol­ecules are connected two-by-two through N—H⋯O hydrogen bonds, with an [R_{2}^{2}](8) graph-set motif, building up a pseudo-dimer arranged around an inversion centre. In the three structures, the C—N bonds in the pyridazine rings correspond to C1—N1 in the structure of (I) [1.363 (2) Å], with a value of 1.363 (2) Å for BARQOA, 1.364 (7) Å for BARQUG and 1.350 (2) Å for YOTVIN. The pyridazinone ring in each mol­ecule is essentially planar, as in the structures of (I) and (II). The conformations of all three compounds resemble those of compounds (I) and (II), with the dihedral angles between the planes of the pyridazine and phenyl rings varying in the range 27.35–82.0°, compared to 46.69 (9) and 21.76 (18)° in (I) and (II), respectively.

5. Hirshfeld surface analysis

Hirshfield surface analyses (Spackman & Jayatilaka, 2009[Spackman, M. A. & Jayatilaka, D. (2009). CrystEngComm, 11, 19-32.]) were carried out using CrystalExplorer (Version 17.5; Turner et al., 2017[Turner, M. J., MacKinnon, J. J., Wolff, S. K., Grimwood, D. J., Spackman, P. R., Jayatilaka, D. & Spackman, M. A. (2017). Crystal Explorer. Version 17.5. University of Western Australia. https://hirshfeldsurface.net.]). The Hirshfeld surfaces and their associated two-dimensional fingerprint plots were used to qu­antify the various inter­molecular inter­actions in the structures of the title compounds. Calculations of the mol­ecular Hirshfeld surfaces (HS) were performed using a standard (high) surface resolution with the three-dimensional dnorm surfaces mapped over a fixed colour scale of −0.6062 (red) to 1.3165 a.u. (blue) for (I) and of −0.2803 (red) to 1.5329 a.u. (blue) for (II). The red spots on the surface indicate the contacts involved in hydrogen bonding. Fig. 5[link](a) illustrates the inter­molecular N—H⋯O hydrogen bonding in (I), with dnorm mapped on the Hirshfeld surface. Likewise, C—H⋯O hydrogen bonding is visualized in Fig. 5[link](b) for compound (II).

[Figure 5]
Figure 5

Fig. 6[link] shows the two-dimensional fingerprint plot of the sum of the contacts contributing to the Hirhsfeld surface of compound (I), represented in normal mode. H⋯H contacts clearly make the most significant contribution to the Hirshfeld surface (48.2%). A significant contribution of H⋯H inter­actions to the total HS (72.2%) was also reported by Ilmi et al. (2019[Ilmi, R., Kansız, S., Dege, N. & Khan, M. S. (2019). J. Photochem. Photobiol. Chem. 377, 268-281.]) for a similar compound. In addition, C⋯H/H⋯C and O⋯H/H⋯O contacts contribute 29.9 and 8.9%, respectively, to the Hirshfeld surface. In particular, the O⋯H/H⋯O contacts indicate the presence of inter­molecular N—H⋯O and C—H⋯O inter­actions.

Two-dimensional fingerprint plots of compound (I) showing the relative contributions of the atom pairs to the Hirshfeld surface.

Similarly, Fig. 7[link] illustrates the two-dimensional fingerprint plot of the sum of the contacts contributing to the Hirhsfeld surface of compound (II). The H⋯H inter­actions appear in the middle of the scattered points in the two-dimensional fingerprint plots, with a contribution to the overall Hirshfeld surface of 34.4% (Fig. 7[link]b). The contributions (16.5%) from the O⋯H/H⋯O contacts, corresponding to the C—H⋯O inter­actions, are represented by a pair of sharp spikes characteristic of such hydrogen bonding (Fig. 7[link]d).

6. Synthesis and crystallization

For the preparation of compound (I), sodium hydroxide (0.5 g, 3.5 mmol) was added to a solution (0.15 g, 1 mmol) of 6-phenyl-4,5-di­hydro­pyridazin-3(2H)-one and benzaldehyde (0.11 g, 1 mmol) in 30 ml of ethanol. The solvent was evaporated under vacuum and the residue was purified by silica-gel column chromatography using hexa­ne/ethyl acetate (7:3 v/v). Colourless single crystals were obtained by slow evaporation at room temperature.

For the preparation of compound (II), potassium carbonate (0.50 g, 3.5 mmol) was added to a solution (0.83 g, 2.5 mmol) of 4-(2,6-di­chloro­benz­yl)-6-phenyl­pyridazin-3(2H)-one in 30 ml of tetra­hydro­furan (THF). The mixture was refluxed for 1 h. After cooling, ethyl bromo­acetate (0.50 g, 3 mmol) was added and the mixture was refluxed for 8 h. The solid material which formed was removed by filtration and the solvent evaporated in vacuo. The residue was purified by silica-gel column chromatography using hexa­ne/ethyl acetate (4:6 v/v). Slow evaporation at room temperature led to colourless single crystals.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3[link]. For the structure of compound (I), the N-bound H atom was located in a difference Fourier map and refined with N—H = 0.86 Å. For the refinement of structure (II), reflections with a θ angle greater than 28° were omitted from the refinement due to their very weak intensities. The meth­oxy group (O3—C20) in this compound was found to be disordered over two sets of sites and was refined with an occupancy ratio of 0.626 (11):0.374 (11) (SIMU, DELU and ISOR commands in SHELX; Sheldrick, 2015b[Sheldrick, G. M. (2015b). Acta Cryst. C71, 3-8.]). For both structures, the C-bound H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.97 Å and Uiso(H) = 1.5Ueq(C) for methyl H atoms or 1.2Ueq(C) otherwise.

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.
