(Received 8 September 2012; accepted 7 October 2012; online 27 October 2012)

The title complex, [Cu(SO4)(C6H8N2)2]·H2O, was obtained under hydro­thermal conditions. The CuII ion is five-coordinated in a distorted square-pyramidal manner by four N atoms from two benzene-1,2-diamine ligands at the base and one O atom from a monodentate sulfate anion at the apex of the coordination polyhedron. N—H⋯O hydrogen bonding between the amino functions and the sulfate groups leads to the formation of layers parallel to (001). C—H⋯O hydrogen bonding inter­actions between the layers consolidate the three-dimensional set-up. There are voids in the structure filled with lattice water mol­ecules that are disordered over three sites in a 0.430 (6):0.270 (6):0.300 (6) ratio.

Comment top

Copper(II) complexes have been widely investigated in both bioinorganic chemistry and coordination chemistry (Datta et al., 2008; Diallo et al., 2008; Khalaji et al., 2009) due to the important role of copper in living organisms and its peculiar coordination chemistry, i.e. the Jahn-Teller distortion. We report here the structure of the title mononuclear copper(II) complex, [Cu(SO4)(C6H8N2)2].H2O.

As shown in Fig. 1, the complex molecule exhibits copper(II) in a distorted [4 + 1] square-pyramidal coordination environment. The basal plane is defined by the amino nitrogen donors of the benzene-1,2-diamine ligand, while the apical position is occupied by one oxygen atom of the SO42- anion. As expected, the organic moieties are approximately planar. In the organic moiety bonded to the copper atom with N1 and N2, the r.m.s. deviation for the non-H atoms is 0.0103 Å, with the maximum deviation of N1 from the mean plane being -0.018 (2) Å. The 1,2 benzene-1,2-diamine molecule linked to Cu(II) with N3 and N4 has a r.m.s deviation for non-H atoms of 0.0173 Å with a maximum deviation from the mean plane being -0.027 (2) Å (for N4). In the crystal structure, π···π stacking interactions occur between adjacent rings, with centroid-centroid separations of 3.583 (2) Å for Cg1···Cg2i (Cg1 and Cg2 are the centroids of the C1—C6 and C7—C12 rings, respectively; symmetry code: (i) (-x, -y, -z)).

In the title compound, the individual molecules are linked by N—H···O hydrogen bonds into a two-dimensional network parallel to (001). In the layers alternating R22(8), R21(4), R12(6) and dual R33(9) (Bernstein et al., 1995) hydrogen-bonded motifs are formed. These layers are linked by means of C15—H15···O22 hydrogen bonds. In terms of graph-set analysis (Etter et al., 1990; Bernstein et al., 1995), the descriptor for this pattern is R24(16).

In the structure voids with an approximate volume of 62 Å3 are present. These voids are filled with a water molecule disordered over three positions with an occupancy ratio of 0.4320 (6):0.270 (6):0.300 (6). Although the H positions of the disordered water molecule could not be located, O···O and O···N interactions suggest likewise an involvement in hydrogen bonding, e.g. N3···O1WC = 2.98 (4) Å, O1···O1WA = 2.73 (3) Å.

Experimental top

Benzene-1,2-diamine (0.2 mmol) and CuSO4.5H2O (0.1 mmol) were dissolved in H2O (5 ml). The mixture was stirred for 16 h at room temperature to give a violet solution. After allowing the resulting solution to stand in air, violet plate-shaped crystals of the compound were formed on slow evaporation of the solvent.

Refinement top

C—H and N—H hydrogen atoms were placed in calculated positions and refined as riding atoms with C—H distances of 0.95 Å with Uiso(H) = 1.2Ueq(C) and N—H distances of 0.92 Å, with Uiso(H) = 1.2Ueq(N).

The water molecule was localized in a difference map and was interpreted as disordered over three positions with the site-occupancy ratio of 0.220 (6):0.270 (6):0.300 (6). The H atoms on the disordered water molecules were not included in the refinement.

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