Bis[(acetato-kappa O-2,O ')bis(4,4 '-dimethyl-2,2 '-bipyridyl-N,N ')zinc(II)] trithionate pentahydrate

Abstract

The title ionic zinc - acetate complex, [Zn(C2H3O2)(C12H12N2) (2)](2)(S3O6) center dot 5H(2)O, contains a ZnN4O2 nucleus provided by the three bidentate ligands acting in a chelating mode. The trithionate unit, in turn, acts as an isolated charge-balancing counter-ion. The structure has a three-dimensional assembly achieved through three different interaction types, viz. Coulomb, hydrogen bonding and pi-pi. The trithionate group and one of the solvent water molecules are disordered around inversion centers.
