The title complex, ipyridyl-N,N')(3-thiapentanedioate-O,S,O')zinc(II)
tetrahydrate, [Zn(C4H4O4S)(C10H8N2)(H2O)].4H(2)O, is mononuclear with
a coordination sphere consisting of one S, two N and three O atoms. Th
e Zn atom is linked to a tridentate thiodiacetate ligand, a bidentate
2,2'-bipyridine ligand and an aqua ligand resulting in a slightly dist
orted octahedral coordination geometry. The molecular units are linked
together in the crystal by an extensive hydrogen-bonding network and
by intermolecular S ... S interactions.
