Crystal structure of dichlorido(1,2-phenylenediamine-κ2N,N′)platinum(II)

Abstract

The PtII atom in the title compound, [PtCl2{(C6H4)(NH2)2}], lies on a twofold rotation axis and has a slightly distorted square-planar coordination environment defined by two N atoms of an 1,2-phenylenediamine ligand and two Cl− ions. In the crystal, the planar complex molecules are stacked parallel to the c axis, resulting in a columnar structure. In a column, an infinite almost straight Pt...Pt chain is formed, suggesting weak metal–metal interactions [Pt...Pt = 3.3475 (8) Å]. The crystal packing is stabilized by a three-dimensional N—H...Cl hydrogen-bonding network between the amino groups and the Cl ligands of adjacent molecules.
