5-cyclooctadiene) and P(C6H5)2(C6H4-p-SO3K) afforded water-soluble complexes MX2P(C6H5)2(C6H4-p-SO3K)}2 (M = Pd; X = Cl (1), M = Pt; X = Cl (2), I (3)) in high yields. Complexes 1–3 were fully characterized by various spectroscopic methods (IR, 1H-, 13C1H}- and 31P1H}-NMR spectroscopy) and elemental analyses. For 1 and 3, a mixture of the cis- and trans-isomer was produced from the reaction. For 2, however,
