Three new palladium complexes containing a difunctional P, N-chelate, namely tris(chloro[1-methyl-1-(6-methyl-2-pyridyl) ethoxy] diphenylphospine-kappa(2) N, P} methylpalladium( II) chloroform solvate, 3[Pd(CH3) Cl(C21H22NOP)] center dot CHCl3, (III), dichloro[2-(2,6-dimethylphenyl)-6-(diphenylphosphinomethyl) pyridine-kappa(2) N, P] palladium(II), [PdCl2(C26H24NP)], (IV), and chloro[2-(2,6-dimethylphenyl)-6-(diphenylphosphinomethyl) pyridine- kappa(2) N, 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 center dot center dot center dot Cl) have been found in all three complexes. Compound ( III) is the first six-membered chloro - methyl - phosphinite P, N-type Pd-II complex to be structurally characterized.
