Bis(2,2'-bipyridine-²N,N')(oxalato-²O,O')zinc(II) pentahydrate

M. Sestan Juric, P. Planinic and G. Giester

Abstract: In the crystal structure of the title compound, [Zn(C₂O₄)(C₁₀H₈N₂)₂]·5H₂O, the Zn atom is coordinated by two O atoms from a bidentate chelating oxalate group and four N atoms from two 2,2'-bipyridine ligands in a distorted octahedral arrangement. Neutral mononuclear [Zn(C₂O₄)(C₁₀H₈N₂)₂] units are linked by intermolecular - stacking interactions of the aromatic rings and a hydrogen-bonding network of uncoordinated water molecules. The compound is isostructural with the Co analogue, [Co(C₂O₄)(C₁₀H₈N₂)₂]·5H₂O [Sestan, Giester & Peric (2004). Acta Cryst. C60, m595-m597], and very similar to the Cu complex containing 1,10-phenanthroline instead of 2,2'-bipyridine, [Cu(C₂O₄)(C₁₂H₈N₂)₂]·5H₂O [Castillo, Luque & Román (2001). J. Mol. Struct. 570, 181-188].
