  ABSTRACT: Platinum mononuclear complex, cis-[PtCl2(PyCN)2] (1, PyCN = 4-cyanopyridine), has been synthesized and characterized by single-crystal X-ray analysis. Compound 1 crystallizes as yellow plates from the reaction of a mixture of K2PtCl4 and PyCN (=1:2) in H2O, that was left to stand at room temperature with the addition of Me2CO. Compound 1 forms the square-planar coordination geometry around the Pt atom coordinated to two Cl– ions and two pyridines of PyCN ligands in cis position. Single crystal of 1 shows the temperature dependent phase transition around 140 K, where the crystal space groups change from P21/c (high temperature) to (low temperature), which is caused by the stabilization of intermolecular interaction.
