||Synthesis and Structural Study of Zinc and Cadmium Thiolate Complexes with Sulfur Rich Coordination Environment|
|Date of Defense
||We have successfully synthesized the zinc and cadmium complexes containing bis(3-trimethylsilyl-2-thiophenyl)phenylphosphine (SiPS2): [NEt4][(SiPS2)Cd(SC6H5)] (1) , [NEt4][(SiPS2)Cd(SC6H11)] (2) , [NEt4][(SiPS2)Cd(SCH2C6H5)] (3) , [NEt4][(SiPS2)Zn(SC6H5)] (4) , [NEt4][(SiPS2)Zn(SC6H11)] (5) and [NEt4][(SiPS2)Zn(SCH2C6H5)] (6) , and characterized them using 31P NMR and mass spectrum.1 and 2 were also characterized by X-ray diffraction methods.|
In the attemprs to get crystals of 4 and 6, we got the oxidized dimer complex 4* and 6* instead. In these complexes the two oxygen atoms of the oxidized ligands and the sulfur atom of the monodentate thiolate ligand bridge both the cadmium centers.
Zinc complexes exhibit distorted tetrahedral structure. However, the cadmium ion tends to form five coordination oxidation dimeric complexes.
