Aqua(2,2'-bipyridyl-N,N')(thiodiacetato-O,O',S)zinc(II) Tetrahydrate

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