Abstract
The title complex, [Zn(CH5N3S)2(C2H6OS)](C6H2N3O7)2·C2H6OS·H2O, is composed of a [Zn(thiosemicarbazide)2(DMSO)]2+ cation (where DMSO is dimethyl sulfoxide), and two picrate anions. In the asymmetric unit, there is also a solvent molecule of DMSO and a water molecule of crystallization. In the cation, the ZnII atom is five-coordinated in a distorted square–pyramidal geometry. It coordinates to the O atom of a DMSO molecule and to the S and one N atom of two thiosemicarbazide molecules, which behave as bidentate ligands coordinating in a trans arrangement. In the crystal, a number of N—H⋯O, O—H⋯O and N—H⋯S hydrogen bonds link the molecules into two-dimensional networks. These networks are further linked via weak C—H⋯O interactions, forming a three-dimensional arrangement. Positional disorder in one methyl group of the coordinated DMSO molecule and in the two picrate anions was observed.
