The title compound, [PdCl(CH3)(C18H15As)(2)], was obtained as yellow c
rystals from the reaction of [PdClMe(1,5-cyclooctadiene)] with triphen
ylarsine. The molecular structure is approximately square planar, with
the two arsine ligands in mutually trans positions, and Pd-As distanc
es of 2.3989 (5) and 2.4067(5) Angstrom, and Pd-Cl and Pd-C distances
of 2.4086 (11) and 2.095 (4) Angstrom, respectively.
