含磷、硫、氮配原子的钴羰基簇合衍生物的合成和表征

The reaction of Co 2(CO) 8 with organic hetrocyclic dithiophosphinate,SP(Fc)(S)N(C 6H 5)NC(Me),gave three cobalt carbonyl cluster derivatives,Co 4(CO) 8(μ CO) 2(μ 4 S)[μ 4 P(Fc)]f,Co 4(CO) 10 (μ 3 S)[μ η 2 P(Fc)N(C 6H 5)NC(Me)] and Co 2(CO) 5[μ η 2 P(Fc)N(C 6H 5)NC(Me)].These clusters were characterized by elementary analysis,IR, 1HNMR and MS spectroscopy.During the reaction,the precursor was cleaved in its P=S,P S,P N and C S bonds,respectively,to give the fragments as ligands as listed above that coordinated to Co atoms to form the new cluster molecules.
