Chloro(phenyl)(1H-pyrazole-KN2)-(triphenylphosphine-KP)palladium(II)

Abstract

In the title compound, [Pd(C6H5)Cl(C3H4N2){P(C6H5)3}], PdClPh(pyrazole)(PPh3), the phenyl and Cl ligands lie mutually trans. The compound is the first structurally characterized complex with four monodentate Cl, P, N and (non-carbenoid) C ligands in a squareplanar four-coordinate palladium(II) environment. The pyrazole ligand is coplanar with the latter array. The pyrazole NH group forms a bifurcated hydrogen bond to Cl, with an intra and intermolecular component.
