It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N,N′,N′′-donating imine ligand led to a mononuclear compound, namely di­chlorido­[N,N-dimethyl-N′-(pyridin-2-yl­methyl­idene)ethane-1,2-di­amine]copper(II) monohydrate, [CuCl2(C10H15N3)]·H2O, 1, while the N,N′,O-donating imine ligand produced a binuclear metal complex, namely μ2-chlorido-di­chlorido­(μ2-2-{[2-(di­methyl­amino)­ethyl]imino­methyl}phenolato)(N,N-dimethyl­ethylene­di­amine)­dicopper(II) 0.11-hydrate, [Cu2(C11H15N2O)Cl3(C4H12N2)]·0.11H2O, 2. The structure of 2 is a remarkable example of a binuclear copper(II) complex containing a single substituted 2-imino­methyl­phenolate ligand that has two copper(II) sites in square-pyramidal coordination.

1. Chemical context

Copper(II) complexes with imine ligands have attracted much attention in the past few decades due to a variety of possible applications, including catalysis [aerobic oxidation of alcohols (Nairn et al., 2006[Nairn, A. K., Archibald, S. J., Bhalla, R., Gilbert, B. C., MacLean, E. J., Teat, S. J. & Walton, P. H. (2006). Dalton Trans. pp. 172-176.]; Alaji et al., 2014[Alaji, Z., Safaei, E., Chiang, L., Clarke, R. M., Mu, C. & Storr, T. (2014). Eur. J. Inorg. Chem. pp. 6066-6074.]), olefin epoxidation (Das et al., 1997[Das, G., Shukla, R., Mandal, S., Singh, R., Bharadwaj, P. K., van Hall, J. & Whitmire, K. H. (1997). Inorg. Chem. 36, 323-329.]) and ring-opening reactions (John et al., 2007[John, A., Katiyar, V., Pang, K., Shaikh, M. M., Nanavati, H. & Ghosh, P. (2007). Polyhedron, 26, 4033-4044.])], and also in medicinal chemistry for both anti­bacterial (Ali et al., 2015[Ali, O. A. M., El-Medani, S. M., Abu Serea, M. R. & Sayed, A. S. S. (2015). Spectrochim. Acta Part A, 136, 651-660.]) and anti­tumour applications (Creaven et al., 2010[Creaven, B. S., Czeglédi, E., Devereux, M., Enyedy, É. A., Foltyn-Arfa Kia, A., Karcz, D., Kellett, A., McClean, S., Nagy, N. V., Noble, A., Rockenbauer, A., Szabó-Plánka, T. & Walsh, M. (2010). Dalton Trans. 39, 10854-10865.]; Pervez et al., 2016[Pervez, H., Ahmad, M., Zaib, S., Yaqub, M., Naseer, M. M. & Iqbal, J. (2016). Med. Chem. Commun. 7, 914-923.]).

[Scheme 1]

Nonmacrocyclic binuclear copper compounds are of inter­est because they can serve as models for metalloproteins and metalloenzymes, as well as representing inter­esting subjects for studying mol­ecular magnetism. Strong magnetic exchange is present in the two copper(II) sites of haemocyanin (Chen & Solomon, 2004[Chen, P. & Solomon, E. I. (2004). Proc. Natl Acad. Sci. USA, 101, 13105-13110.]), which represents a challenge that must be considered when synthetic models are developed. One strategy, introduced by Robson (1970[Robson, R. (1970). Inorg. Nucl. Chem. Lett. 6, 125-128.]), makes use of symmetrical imino ligands containing a phenolate bridge to keep the CuII atoms close in space. Imines represent an inter­esting class of ligands because they can be easily synthesized and fine-tuned to the desired application by introducing extra donor atoms or groups with the desired steric properties into the side chains. A limited number of binuclear copper(II) compounds containing substituted 2-imino­methyl­phenole ligands have been reported in the literature (Gao et al., 2011[Gao, Y., Ji, Y., Ding, S., Liu, Z. & Tang, J. (2011). Z. Anorg. Allg. Chem. 637, 2300-2305.]; Tang et al., 2008[Tang, J., Sánchez Costa, J., Pevec, A., Kozlevčar, B., Massera, C., Roubeau, O., Mutikainen, I., Turpeinen, U., Gamez, P. & Reedijk, J. (2008). Cryst. Growth Des. 8, 1005-1012.]). This kind of structure, where the polydentate ligand has fewer donor atoms than the coordination number of the metal centre, is of inter­est for the design of more flexible binuclear model compounds.

We describe here the crystal structures of mononuclear (1) and binuclear (2) copper(II) complexes with tridentate imine-containing ligands obtained by a one-pot synthetic method. The nuclearity of the complexes was shown to be directed by the different donor atoms present in the imine ligand.

2. Structural commentary

The mononuclear compound 1 has the central CuII cation in a square-pyramidal coordination environment (Fig. 1[link]a). The CuII cation is displaced from the least-squares plane defined by the four coordinating atoms of the square base (N1, N2, N3 and Cl2) by 0.334 Å. The bond lengths to these atoms are: Cu—N1 = 2.060 (2), Cu—N2 = 1.978 (2), Cu—N3 = 2.058 (2) and Cu—Cl2 = 2.2639 (8) Å; the Cu—Cl bond length to the apical Cl1 atom that completes the first coordination sphere is considerably longer, at 2.5013 (8) Å. In order to assess the coordination geometry of copper(II) more qu­anti­tatively, the τ5 index as defined by Addison et al. (1984[Addison, A. W., Rao, T. N., Reedijk, J., van Rijn, J. & Verschoor, G. C. (1984). J. Chem. Soc. Dalton Trans. pp. 1349-1356.]) can be used. A perfect square-pyramidal coordination geometry is defined by τ5 = 0.0, while it is 1.0 for a perfect trigonal–bipyramidal coordination geometry. For compound 1, τ5 is 0.059, indicating an almost perfect square-pyramidal coordination geometry.

(b) Packing of the crystal structure of 1, viewed along the a axis, highlighting the hydrogen-bonded chain (comprising the water mol­ecules and the axial chloride ligand) as well as the π-stacking.

The binuclear compound 2 has two copper(II) cations, both in a square-pyramidal coordination environment (Fig. 2[link]a). The presence of the phenolate group in the structure of the imine ligand directs the reaction with copper(II) cations to form a binuclear coordination compound, in contrast with the mononuclear species 1 obtained when a pyridine group is present in the ligand. Atoms Cu1 and Cu2 in 2 are displaced from the least-squares plane defined by the four coordinating atoms of the square base (N1, N2, O1 and Cl2 for Cu1; N3, N4, O1 and Cl3 for Cu2) by 0.299 and 0.170 Å, respectively. The distances from the central copper(II) cations to these ligating atoms are: Cu1—N1 = 2.068 (2), Cu1—N2 = 1.959 (2), Cu1—O1 = 1.968 (1) and Cu1—Cl2 = 2.2958 (5) Å; Cu2—N3 = 2.021 (2), Cu2—N4 = 2.040 (2), Cu2—Cl3 = 2.2501 (5) and Cu2—O1 = 2.004 (1) Å. The two Cu—Cl distances to the apical Cl atoms are likewise longer, Cu1—Cl1 = 2.5476 (5) Å and Cu2—Cl2 = 2.5938 (5) Å. The Cu⋯Cu distance within the binuclear complex is 3.2525 (5) Å. In compound 2, the τ5 index for Cu1 is 0.294 and for Cu2 0.260, indicating more distorted square-pyramidal coordination environments for both central copper(II) cations.

H atoms not participating in hydrogen bonding have been omitted for clarity.

After refining the structure of the binuclear compound 2, a solvent-accessible void of 42 Å3 was detected by a PLATON analysis (Spek, 2009[Spek, A. L. (2009). Acta Cryst. D65, 148-155.]). The highest residual electron-density peak fitted perfectly within this void. We have modelled the corresponding site as an O atom of a partially occupied water mol­ecule, showing an occupancy of 0.11. Given the low occupancy, this water mol­ecule is not represented in the mol­ecular view nor in the crystal packing (Fig. 2[link]).

3. Supra­molecular features

The presence of a water mol­ecule in the crystal structure of the mononuclear compound 1 leads to the formation of a hydrogen-bonded chain along [101] involving the apical ligand Cl1 (Fig. 1[link]b and Table 1[link]). In addition, a short contact between the C—H group of the imine group and the apical Cl1 ligand is observed (C5—H5⋯Cl1, Table 1[link]). Finally, a similar C—H⋯Cl inter­action between an aromatic H atom of the pyridine ring and the Cl2 ligand of the square base likewise contributes to the packing in the solid state (C9—H9⋯Cl2, Table 1[link]). Besides these hydrogen bonds, an offset π–π stacking is observed between adjacent pyridine rings [centroid-to-centroid distance of 3.5709 (18) Å; symmetry code: −x, −y, −z].

In terms of inter­molecular contacts, a single set of hydrogen bonds is present in the crystal structure of 2, established between the non-substituted terminal amine group of N,N-di­methyl­ethylenedi­amine and the apical chloride ligand Cl1 (Fig. 2[link]b and Table 2[link]). Similar to compound 1, a nonclassical hydrogen bond between an aromatic H atom of the phenolic ring and the Cl2 ligand also contributes to the inter­molecular network (C8—H8⋯Cl2, Table 2[link]). Differing from the structure of 1, a C—H⋯π inter­action is observed for compound 2, with a C12—H12⋯centroid(phen­yl) distance of 3.393 (2) Å (symmetry code: −x + 1, −y + 1, −z + 1). The partly occupied water mol­ecule participates in a hydrogen bond with the μ2-bridging Cl2 ligand (Table 2[link]).

4. Database survey

The structures of the mononuclear and binuclear copper(II) compounds 1 and 2 were compared with analogues found in the Cambridge Structural Database (CSD; Groom et al., 2016[Groom, C. R., Bruno, I. J., Lightfoot, M. P. & Ward, S. C. (2016). Acta Cryst. B72, 171-179.]), using the queries shown in Fig. 3[link]. Only binuclear CuII compounds containing a single μ2-(mono­imino­methyl)­phenolate ligand were considered as analogues of 2. A total of 12 hits were found as analogues of 1, while 11 hits were found for analogues of 2, including both mono- and bis­(imino­methyl)­phenolate ligands. Averages of selected bond lengths (see representations in Fig. 3[link]) were obtained using ConQuest (Version 1.19) and the statistical analysis module in Mercury (Version 3.9) (Macrae et al., 2008[Macrae, C. F., Bruno, I. J., Chisholm, J. A., Edgington, P. R., McCabe, P., Pidcock, E., Rodriguez-Monge, L., Taylor, R., van de Streek, J. & Wood, P. A. (2008). J. Appl. Cryst. 41, 466-470.]). The averaged values are collated in Table 3[link] and are in good agreement with the bond lengths in the structures of 1 and 2.

The closest relation to 1 is associated with the nonhydrated analogue (CCDC entry TAWMEK; Yuan & Zhang, 2005[Yuan, W.-B. & Zhang, Q. (2005). Acta Cryst. E61, m1883-m1884.]), which has the CuII cation in a more distorted square-pyramidal coordination geometry than 1, with the following bond lengths: Cu—N1 = 2.275 (2), Cu—N2 = 2.104 (2) and Cu—N3 = 2.236 (2) Å, and almost identical Cu—Cl1 = 2.2573 (5) and Cu—Cl2 = 2.22561 (6) Å distances. The CuII cation is displaced from the mean plane defined by the four coordinating atoms of the square base by 0.622 Å. While for 1 τ5 = 0.0593, for the structure of TAWMEK τ5 = 0.302. The differences in the coordination environment of copper(II) probably arise as a consequence of the presence of the hydrogen-bonded network established between the chloride ligands and the water mol­ecules in the crystal structure of 1. The coordination spheres around the CuII cations in 1 and TAWMEK are compared in Fig. 4[link].

Regarding the binuclear compound 2, the search returned only two examples of binuclear CuII complexes containing a single μ2-(mono­imino­methyl)­phenolate ligand [VAMJIE (Gao et al., 2011[Gao, Y., Ji, Y., Ding, S., Liu, Z. & Tang, J. (2011). Z. Anorg. Allg. Chem. 637, 2300-2305.]) and UFATEB (Tang et al., 2008[Tang, J., Sánchez Costa, J., Pevec, A., Kozlevčar, B., Massera, C., Roubeau, O., Mutikainen, I., Turpeinen, U., Gamez, P. & Reedijk, J. (2008). Cryst. Growth Des. 8, 1005-1012.])]. The two structures have one CuII cation in a square-pyramidal environment, comprising the tridentate imine ligand, and one octa­hedrally surrounded CuII site, bridged by the phenolate and a chloride ligand. Structure 2, on the other hand, comprises a binuclear copper(II) complex with a single μ2-(mono­imino­methyl)­phenolate ligand that has two CuII co­ordination sites in square-pyramidal environments. The co­ordination spheres around the two CuII cations in 2 and UFATEB are compared in Fig. 4[link].

5. Synthesis and crystallization

Copper(II) chloride dihydrate was purchased from Vetec (Brazil). N,N-di­methyl­ethylene­di­amine, pyridine-2-carbox­aldehyde and salicyl­aldehyde were purchased from Sigma–Aldrich and used without further purification.

Compound 1, C10H15Cl2CuN3·H2O, was obtained as follows. In a 10 ml beaker, N,N-di­methyl­ethylene­di­amine (0.10 mmol, 65.6 µl) was combined with pyridine-2-carbox­aldehyde (0.10 mmol, 10 µl) in methanol (200 µl). The reaction was carried out at room temperature for 24 h. Afterwards, solid CuCl2·2H2O (0.10 mmol, 2.8 mg) was added to the reaction mixture. A polycrystalline green compound was obtained, filtered off and washed with small amounts of cold methanol. Elemental analysis was performed on a Perkin–Elmer CHNS-O 2400. Analysis, calculated for C10H15Cl2CuN3·H2O: C 36.4, H 5.2, N 12.7%; found: C 36.8, H 4.8, N 13.0%. The supernatant was transferred to an amber flask and green crystals suitable for single-crystal X-ray diffraction were obtained by slow evaporation.

Compound 2 (C15H27Cl3Cu2N4O·0.11H2O) was obtained following the same synthetic procedure as used for 1, but replacing pyridine-2-carbox­aldehyde by salicyl­aldehyde (11 µl). Green needle-like crystals of 2 were obtained by slow evaporation of the supernatant. Since only a few crystals were obtained, no further analytical data were acquired.

6. Refinement details

Crystal data, data collection and structure refinement details are summarized in Table 4[link]. H atoms were placed in calculated positions, with C—H = 0.99 (CH2) or 0.95 Å (CH), with Uiso(H) = 1.2Ueq(C), and C—H = 0.98 Å (CH3) and Uiso(H) = 1.5Ueq(C). For structure 1, the H atoms of the water mol­ecule were refined with an O—H distance restraint of 0.82 (1) Å and a H⋯H separation of 1.29 (2) Å, and with Uiso(H) = 1.5Ueq(O). For structure 2, the H atoms of the amine functionality (H3A and H3B) were refined freely. The occupancy of the partly occupied water solvent mol­ecule was refined to a value of 0.11 (1); for this mol­ecule, H atoms were not located and they were not considered in the final model.

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.
