Pd (II) chelates of 1,1-dimethyl-3-(4-methyl-2-thiazolyl) thiourea and related N-(2-thiazolyl)-thioureas were prepared and their molecular structures were determined by means of spectroscopic, thermochemical, and X-ray crystallographic measurements, in order to establish the identity of the colored substances in the spectrophotometric determination of Pd (II) with the thiazolyl-thioureas. The results indicated that Pd (II) formed 1 : 2 chelates with the thiazolylthioureas and that the ligands were bidentate and coordinated through the thiourea sulfur and thiazole nitrogen atoms. The geometry of Pd (II) coordination was roughly square-planar and the configuration of the two thiazolylthiourea molecules was cis.
