The copper complex [CuCl 2 (TzHy)] has been synthesized and its crystal structure determined. The coordination complex contains polymeric [CuCl 2 (TzHy)] n chains in which the units are linked by μ‐chloro bridges. The chains run along the crystallographic c axis. The geometry around the copper(II) is best described as distorted square pyramidal. The equatorial positions are occupied by Cl(1) and Cl(2) ligands and one thiazolinic nitrogen atom and another hydrazinic nitrogen atom, from TzHy ligand. The axial position is occupied by the Cl(2b) ligand. The magnetic susceptibility measurements in the temperature range 4 – 290 K show a weak antiferromagnetic intrachain interactions ( J = −8.6 cm −1 ).
