Abstract We report on the reaction between bis(dithiophosphonate) ligands of the type [NH4]2[S2P(1,4-C6H4OMe)(OCH2CH=CHCH2O)P(1,4-C6H4OMe)S2}] (L1) and the two common metal nitrates, Zn(NO3)2·6H2O and Cd(NO3)2·4H2O, in aqueous solution. The reaction led to… Click to show full abstract
Abstract We report on the reaction between bis(dithiophosphonate) ligands of the type [NH4]2[S2P(1,4-C6H4OMe)(OCH2CH=CHCH2O)P(1,4-C6H4OMe)S2}] (L1) and the two common metal nitrates, Zn(NO3)2·6H2O and Cd(NO3)2·4H2O, in aqueous solution. The reaction led to interesting new dinuclear complexes of the type [M2{S2P(1,4-C6H4OMe)(OCH2CH=CHCH2O)P(1,4-C6H4OMe)S2}2] [M = Zn (1) and Cd (2)] in M:L molar ratio (1:1). Based on X-ray structural studies, each ligand is involved in two bonding modes to the metal center: bridging and chelating, and each complex contained a four, eight and eleven-membered metallacycle. This versatile but underutilized ligand type is potentially suitable for a variety of different bonding modes of new complexes to be discovered.
