Hemi[4-(carboxymethoxy)phenylsulfanylacetato-²O,O']hemi[4-(carboxymethylsulfanyl)phenyloxyacetato]bis(1,10-phenanthroline-²N,N')cadmium(II) 4-(carboxymethoxy)phenylsulfanylacetate dihydrate

Abstract: The reaction of cadmium nitrate with 4-(carboxymethoxy)phenylsulfanylacetic acid in the presence of phenanthroline at a pH of 6 affords the salt, [Cd(C₁₀H₉O₅S)(C₁₂H₈N₂)₂](C₁₀H₉O₅S)·2H₂O. The Cd atom in the cation is chelated by two phenanthroline units and one carboxylate from the monoanionic ligand in a distorted octahedral geometry. The coordinated monoanion shows disorder which results in a 50:50 mixture of 4-(carboxymethoxy)phenylsulfanylacetate and 4-(carboxymethylsulfanyl)phenyloxyacetate coordinated to the cadmium. The cation and uncoordinated anion interact to form a linear chain.
