The central CuN2O4 motif of the title compound, [Cu(ClO4)2(C10H8N2)(H2O)2], exhibits a Jahn–Teller-distorted octa­hedral geometry around the metal atom, showing a considerably long Cu—O bond distance of 2.5058 (12) Å towards the second perchlorate group, giving a (4 + 1+1)-type coordination mode. In the crystal, the components are linked via inter­molecular O—H⋯O hydrogen bonds, forming layers parallel to (001). Additional stabilization within these layers is provided by ππ [centroid–centroid distances of 3.7848 (9)–4.4231 (9) Å] stacking inter­actions.

Supporting information


Comment top

Copper(II) complexes containing O, N-donor atoms are very important owing to their significant catalytic activity in the preparative oxygenation of phenols and other substances, and their significant antibacterial and anticancer activity (Kurzak et al., 1999).

The asymmetric unit of (I), and the atomic numbering used, is illustrated in Fig. 1. The CuII atom is located in a Jahn-Teller distorted octahedral coordination environment with two N atoms from one 2,2'-bipyridine ligand (N1, N2) (d(Cu—N) = 1.9723 (13)–1.9805 (12) Å) and two O atoms from two water molecular adopting a planar arrangement (d(Cu—O) = 1.9621 (12)–1.9719 (12) Å). The Cu(II) center is displaced out of the N2O2 plane by 0.028 (2)Å in the direction of one of perchlorate ligand with d(Cu—O9) = 2.3287 (12) Å. The O atom of the second perchlorate group occupies a sixth coordination site at a longer distance of 2.5058 (12) Å, completing the overall (4 + 1 + 1) type coordination. O9 is situated slightly off the axial direct of the square pyramid, nevertheless it is close enough to the Cu atom (Hathaway, 1973). The bipyridine rings of the 2,2'-bipyridine ligand are twisted relative to each other at 2.2 (8)°.

The crystal structure can be described as alternating layers of polyhedral (ClO4 tetrahedrals and CuN2O4 octahedrals) perpendicular to c axis (Fig. 2).

The crystal packing in (I) is governed by classical hydrogen bond,viz. water molecules and perchlorate (Table 1, Fig. 3). All water H atoms are involved in these hydrogen bonds In the crystal, the components of the structure are linked via intermolecular O—H···O hydrogen bonds to form a two-dimensional layers parallel to (001) plane (Fig. 3). Additional stabilization within these layers is provided by ππ [3.7848 (9)Å to 4.4231 (9) Å] stacking interactions. These interaction bonds link the molecules within the layers and also link the layers together and reinforcing the cohesion of the structure.

The combination of these hydrogen bonds generates an alternating centrosymmetric rings in two-dimensional network which can be described by the graph-set motif R42(12) and R44(16) (Bernstein et al. 1995; Etter et al., 1990).

Experimental top

The title compound was prepared by adding a methanol solution (10 ml) of copper (II) acetate monohydrate (0.1 mmol) to a methanol solution (10 ml) of 2,2'-bipyridine (0.1 mmol) and (1 ml) the perchloric acid. The mixture was stirred for about 2 h at 323 K and filtered. The filtrate was slowly evaporated at room temperature to yield blue crystals of (I) suitable for X-ray analysis.

Refinement top

H atoms of water molecule were located in difference Fourier maps and refined isotropically using restraints Uiso(H) = 1.5Ueq(O). The remaining H atoms were localized on Fourier maps but introduced in calculated positions and treated as riding on their parent atoms (Caryl) with Caryl—Haryl=0.93Å and Uiso(Haryl)=1.2Ueq(Caryl).

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
