Abstract

In the centrosymmetric trinuclear Zn^II⋯Ca^II⋯Zn^II title complex, [CaZn₂(CH₃COO)₆(C₁₂H₁₂N₂)₂], the Ca^II ion lies on an inversion centre and is octahedrally coordinated by six acetate O atoms. The Zn^II ion is coordinated by two N atoms from a bidentate dimethylbipyridine ligand and three O atoms from acetate ligands bridging to the Ca^II ion, leading to a distorted square-pyramidal coordination sphere. The Zn⋯Ca distance is 3.4668 (5) Å.

1. Comment

Multimetallic coordination complexes have many practical applications in a number of areas including molecular magnetism, crystal engineering, catalysis, gas storage, ion exchange, nonlinear optics, and biomimetic materials (Rao et al., 2004). In general, multimetallic complexes invoves azido, cyano, isocyanate, isothiocyanate, hydroxo, oxo and carboxylate ions (Herold & Lippard, 1997). Multimetallic complexation is also important in many biological systems; for example, in metalloenzymes where carboxylate ions serve as bidentate ligands showing three different coordination modes: syn-syn, syn-anti and anti-anti (Voegtli et al., 2000). However, as compared to traditional mononuclear metal complexes, the chemistry of multimetallic complexes with well established structures is much under developed. In our continuing interests in dinuclear metal complexes (Saeed et al., 2010; Mendy, et al., 2010) for anion binding, we attempted to obtain zinc complex of mixed ligands with 4,4'dimethyl-2,2'-bipyridine and hexa N-substituted (p-cyano benzamido) para xylyl based octa-aza cryptand. However, single-crystal structure analysis reveals the formation of the title compound. The source of calcium could be a contaminant from the reagents used for this reaction. Herein, we present a structural characterization of 4,4'-dimethyl-2,2'-bipyridine coordinated heterotrinuclear Zn^II—Ca^II—Zn^II hexa-carboxylate complex.

The heteronuclear complex is crystallized in triclinic P-1 space group, with one calcium ion, two zinc ions, six acetate and two 4,4'-dimethyl-2,2'-bipyridine groups. As can be seen in Figure 1, one calcium ion is located at the center surrounded by two zinc ions and six acetate ions. Two zinc ions from opposite sides are linearly coordinated with the central calcium ion forming trinuclear Zn^II–Ca^II–Zn^II backbone, while six acetate ions are coordinated with six Ca–O bonds. In addition, each zinc is hexacoordinated with two N atoms from one bipyridine and four O atoms from four six acetates, forming a centrosymmetric complex. In the complex, four acetates serve as bidentate ligands to coordinate with both calcium and zinc ions, while each of other two serves as a monodentate ligand for a single zinc ion. Both Ca^II and Zn^II ions are connected by two pairs of carboxylate ligands in syn±syn, and syn±anti bridging modes (Voegtli et al., 2000). Another pair of carboxylates is coordinated with one Ca^II ion and two Zn^IIvia (O,O') bridges. The distorted square pyramidal geometry around the Zn^II ion is completed by the coordination of N atoms of 4,4'-dimethyl-2,2'-bipyridine.

2. Experimental

4,4'-dimethyl-2,2'-bipyridine (0.5 g, 2.71 mmol) and zinc acetate (0.9 g, 4.1 mmol) of was added to hexa N-substituted (p-cyano benzamido) para xylyl based octa-aza cryptand (0.15 g) in 20 mL of ethanol-water (1:1, v/v) mixture at room temperature (Hossain et al., 2010). The mixture was further diluted with 10 mL DMSO solvent with constant stirring. Only a few crystals were grown after a week, which was characterized by single-crystal diffraction method. Further analysis was not possible because of the small quantity of the product.

Special details

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.
