Crystal Structure of cis-[PtCl2(PyCN)2] (PyCN = 4-Cyanopyridine) Showing Temperature Dependent Single-Crystal-to-Single-Crystal Transformation ()
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.
