Hexa-μ-acetato-1:2κ(4) O,O';1:2κ(2) O:O;2:3κ(4) O,O';2:3κ(2) O:O-bis-(4,4'-dimethyl-2,2'-bi-pyridine)-1κ(2) N,N';3κ(2) N,N'-2-calcium-1,3-dizinc.

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 octa-hedrally coordinated by six acetate O atoms. The Zn(II) ion is coordinated by two N atoms from a bidentate di-methyl-bipyridine 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.

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.
