P(OPh)3; R = OMe, M = Pt or Pd, L = PPh3). Single-crystal X-ray diffraction studies have been carried out on [[graphic omitted]H(COPh)}(PPh3)2]·2CH2Cl2, [(6a)] and [[graphic omitted]H(COPh)}(PMePh2)2]·CH2Cl2·H2O [(6i)]. Crystals of (6a)·2CH2Cl2, are triclinic, space group P, Z= 2, in a unit cell with lattice parameters a= 20.835(2), b= 10.628(2), c= 12.577(4)Å, α= 109.6(1), β= 105.8(1), and γ= 91.4(l)°
