Abstract
In the title complex, [CdCl2(C4H6N2S)2], the Cd atom has a distorted tetrahedral coordination geometry, with two Cl− and two monodentate neutral thione ligands bonded through S. There are intramolecular N—H⋯Cl and intermolecular N—H⋯S hydrogen bonds, generating centrosymmetric dimers.
Highlights
The essentially planar Hmimt ligands are in their neutral thione form
Their geometry is typical of this ligand attached in a monodentate fashion through S to metal ions; the mean C S bond length for almost 100 occurrences of this ligand in 39 crystal structures in the Cambridge Structural Database is 1.718 A, over a range of 1.684–1.750 Awith the omission of a few outliers, and compares with C S bond lengths of 1.729 (3) and 1.733 (3) Ain (I)

Summary
In the title complex, [CdCl2(C4H6N2S)2], the Cd atom has a distorted tetrahedral coordination geometry, with two ClÀ and two monodentate neutral thione ligands bonded through S. The essentially planar Hmimt ligands are in their neutral thione form Their geometry is typical of this ligand attached in a monodentate fashion through S to metal ions; the mean C S bond length for almost 100 occurrences of this ligand in 39 crystal structures in the Cambridge Structural Database (version 5.26 with two updates, May 2005; Allen, 2002) is 1.718 A , over a range of 1.684–1.750 Awith the omission of a few outliers, and compares with C S bond lengths of 1.729 (3) and 1.733 (3) Ain (I).
