Synthesis and Characterization of Cobalt Carbonyl Clusters Containing S,P Using "Low Tempreture Solid Reaction Method

选取了四个含P、S、N杂原子的化合物作为配位基前体:

Reaction of Co2(CO)8 with four different ligand precursors containing P,S ,N atoms Using low tempreture solid reaction method yield four nuclear cobalt carbonyl cluster derivatives. Their formulas are as follows:Co4(μ4C)(μ4S)(CO)10 (Ⅰ),Co4(CO)10(μ4S)(μ4PC6H4OCH3) (Ⅱ),Co4(CO)10(μ4S)(μ4PC6H4OC2H5) (Ⅲ) and Co4(CO)10(μ4S)(μ4P(Fc)) (Ⅳ).The four ligand precussors are as follows:CNH2SNH2NSPNMeSPhOMeNSPNMeSPhOEtNSPNMeSFcPh(L1)(L2)(L3)(L4)These compounds are characterized by elementary analasys,IR(υco),1HNMR and MS spectroscopy.Ⅰ is a new four nuclear cobalt carbonyl cluster derivative . Ⅱ,Ⅲ,Ⅳ clusters have the same structure as known clusters which are prepared by liquid reaction method.
