The title compound, [Cu(C₂H₆OS)₄(C₁₀H₈N₂)](ClO₄)₂, contains a Cu^II ion with a distorted octahedral coordination environment, bonded by four O atoms of the monodentate dimethyl sulfoxide ligands and two N atoms of the bidentate chelating 2,2′-bipyridine ligand. The equatorial Cu—N and Cu—O bond lengths are in the range 1.979 (2)-1.998 (3) Å. The axial Cu—O bond distances are 2.365 (2) and 2.394 (2) Å. In the crystal, the complex cations and perchlorate anions are connected by numerous C—H⋯O hydrogen bonds, which leads to additional stabilization of the structure. The perchlorate anion is disordered over two sets of sites with a 0.716 (3):0.284 (3) occupancy ratio.

Comment top

2,2'-Bipyridyl (2,2'-bipy) is a well known neutral bidentate ligand which is widely used in coordination chemistry, in particular, for the preparation of mixed ligand complexes (Fritsky et al., 2004; Kanderal et al., 2005). It is also often used in the synthesis of discrete polynuclear complexes in order to prevent formation of coordination polymers by blocking a certain number of vacant sites in the coordination sphere of a metal ion (Fritsky et al., 2006). The title compound was obtained unintentionally during an attempt to synthesize a mixed-ligand complex of Cu^II with pyridine-2-hydroxamic acid in the framework of our project on study of metal complexes of heterocyclic hydroxamic acids (Świątek-Kozłowska et al., 2002; Golenya et al., 2012a). The crystal structure of the title complex has not hitherto been reported.

The title compound, [Cu(C₁₀H₈N₂)(C₂H₆OS)₄](ClO₄)₂, consists of a cationic Cu²⁺ complex and two perchlorate anions (Fig. 1). The central atom is in distorted octahedral environment formed by two nitrogen donor atoms of bidentately coordinated molecule of 2,2'-bipyridine and by four oxygen atoms of dimethyl sulfoxide molecules. The equatorial plane of the coordination polyhedron is consisting of two nitrogen atoms of 2,2'-bipyridyl and two oxygen atoms of two dimethyl sulfoxide ligands. The axial positions are occupied by oxygen atoms of other two dimethyl sulfoxide ligands. The equatorial Cu—N and Cu—O bond lengths are in the range 1.979 (2) – 1.998 (3) Å. The axial Cu—O bond distances are 2.365 (2) Å and 2.394 (2) Å. The coordination bond lengths Cu—N and Cu—O are typical for distorted octahedral Cu^II complexes with the nitrogen and oxygen donors (Fritsky et al., 1998; Świątek-Kozłowska et al., 2000; Sliva et al., 1997). The N2—Cu1—N1 bite angle is decreased to 81.45 (11)°, which is a consequence of the formation of five-membered chelate ring. The C—N and C—C bond lengths in the pyridine rings are normal for 2-substituted pyridine derivatives (Fritsky et al., 2000; Iskenderov et al., 2009; Moroz et al., 2010; Moroz et al., 2012).

In the crystal structure, the complex cations and perchlorate anions are connected by numerous intermolecular C—H···O hydrogen bonds, in which the aromatic and methyl carbon atoms act as donors while the perchlorate oxygen atoms act as acceptors, which contribute to the stabilization of the structure (Fig. 2). There are also stacking interactions between the aromatic rings of the 2,2'-bipyridine molecules belonging to the neighboring complex molecules with shortest non-covalent contacts C(2)···C(6) (-x, 1 - y, -z) = 3.369 (5) and C(4)···C(10) (-x, 1 - y, -z) = 3.390 (5) Å (Fig. 2).

Experimental top

The title compound was obtained unexpectedly during an attempt to synthesize a mixed-ligand complex of Cu^II with pyridine-2-hydroxamic acid (Golenya et al., 2012b) in aqueous methanol solution. Cu(ClO₄)₂.6H₂O in methanol (0.0370 g, 0.1 mmol) was added to solution of 2,2'-bipyridine (0.156 g, 1 mmol) and pyridine-2-hydroxamic acid (0.069 g, 0.5 mmol) in methanol (7 ml), afterwards the obtained transparent blue solution left for evaporation in the air at ambient temperature. The obtained dry solid residue was dissolved in 5 ml DMSO and set for crystallization by slow diffusion of 2-propanol vapors at room temperature. During 12 h the blue crystals suitable for X-ray analysis were obtained. They were filtered off, washed with 2-propanol and dried in the air. Yield: 73%. Elemental analysis calc.

Special details top

Experimental. The C—H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.95(CH), 0.98(CH₃) and U_iso = 1.2 or 1.5 U_eq(parent atom) for CH and CH₃, respectively. One of the perchlorate anions were found to be disordered over two positions with occupancy factors 0.716/0.284. All atoms were refined with anisotropic displacement parameters except the oxygen atoms of the disordered perchlorate which were refined isotropically. Cl—O bond distances and O···O separations of both (minor and major) fractions of the disordered perchlorate anion as well as the ordered perchlorate (as a model) were restrained to have identical values. For each corresponding pair of the oxygen atoms of the disordered perchlorate anion, the isotropic displacement parameters were restrained to have identical values.

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.

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 > 2sigma(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.
