Chloro(phenyl)(1H-pyrazole-kappa N-2)-(triphenylphosphine-kappa P)palladium(II)

In the title compound, [Pd(C6H5)Cl(C 3H4N2)(P(C6H5) 3}], 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 square-planar 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.
