Synthesis and crystal structure of scandium(III) and cadmium(II) thiocyanato complexes with dimethylsulfoxide

Two novel complex compounds, molecular fac-[Sc(NCS)3(DMSO)3] and polymeric chain [Cd(NCS)4/2(DMSO)2]∞ (DMSO = dimethylsulfoxide), were synthesized and structurally characterized. In both complexes, the metal atoms have octahedral coordination with the NCS− ion serving two different functions: as a terminal ion with the coordination via N in Sc complex and as a bridge ligand with the coordination via N and S in the case of Cd compound, respectively. The DMSO ligands are coordinated by oxygen atoms.
