Three new palladium complexes containing a difunctional P,N-chelate, namely tris(chloro{[1-methyl-1-(6-methyl-2-pyridyl)ethoxy]diphenylphospine- κ2N,P}methylpalladium(II)chloroform solvate, 3[Pd(CH 3)Cl(C21H22NOP)]·CHCl3, (III), dichloro[2-(2,6-dimethylphenyl)-6-(diphenylphosphinomethyl)pyridine- κ2N,P]palladium(II), [PdCl2(C26H 24NP)], (IV), and chloro[2-(2,6-dimethylphenyl)-6- (diphenylphosphinomethyl)pyridine-κ2N,P]methylpalladium(II), [Pd(CH3)Cl(C26H24NP)], (V), are reported. Geometric data and the conformations of the ligands around the metal centers, as well as slight distortions of the Pd coordination environments from idealized square-planar geometry, are discussed and compared with the situations in related compounds. Non-conventional hydrogen-bond interactions (C - H...Cl) have been found in all three complexes. Compound (III) is the first six-membered chloro-methyl-phosphinite P,N-type PdII complex to be structurally characterized.
