By addition of different neutral or monoanionic ligands to 2, the bridging chlorides can be cleaved and a variety of hydrophilic or water-soluble mononuclear organometallic palladium(II) complexes of the type [PdC6H4(C(O)N═TPA-kC,N)-2}(L-L)] (L-L = acac (3); S2CNMe2 (4); 4,7-diphenyl-1,10-phenanthrolinedisulfonic acid disodium salt C12H6N2(C6H4SO3Na)2 (5)), [PdC6H4(C(O)N═TPA-kC,N)-2}(L)Br] (L = P(mC6H4SO3Na)3
