Molecular and Crystal Structure of trans-(Dicyanato)-bis(triphenylphosphine)palladium(II)

Abstract

The triphenylphosphine (PPh3) displaces the acetonitrile from [PdCl2(CH3CN)2], and subsequent addition of the potassium cyanate causes substitution of the chloro ligand by NCO- to yield trans-[Pd(NCO)2(PPh3)2]. The complex was characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The title compound was crystallized in a triclinic system, space group P1 with a = 9.213(3)A, b = 9.781(7)A, c = 10.483(5)A, α = 111.39(5)°, β = 93.49(3)°, γ = 103.81(4)°, V = 845.0(1)A3, Z = 1. The coordination geometry around Pd(II) in this complex is nearly square-planar, with the ligands in a trans relationship.
