碩士 === 國立成功大學 === 化學系 === 103 === Our laboratory has developed a series of phosphine-thiolate ligands in order to understand metal thiolate chemistry. It is anticipated the information provided from this study can bring insights for understanding the metal-sulfur chemistry in biological systems as well as in toxicity. In this thesis, diphosphine-dithiolate ligand (P2S2) was utilized for exploring metal chemistry. 31P, 207Pb NMR in solid and solution state were applied on two lead(II) compelexes, Pb(P2S2”) (1) and [Pb(P2S2”)]2·[Pb2(P2S2”)2] (2). Pb(P2S2”) (1) is a monolead(II) species binding with a P2S2” ligand. [Pb(P2S2”)]2·[Pb2(P2S2”)2] contains two monolead(II) units and a dimeric unit. These compounds were synthesized and characterized in our laboratory before. In addition, a hexacopper(I) complex of P2S2” ligand, [Cu3(P2S2”)(Im)(TMSPhS)]2 , has been isolated and characterized by X-ray crystallography and spectroscopies. Finally, iron carbonyl chemistry with P2S2” ligand was also been explored. The isolated compound was identified as cis-Fe(P2S2”)(CO)2 by comparing the spectroscopies with the other analogue cis-Fe(P2S2*)(CO)2, that is synthesized and well characterized in our laboratory.
