含磷、硫、氮原子配位基的三核、四核钴羰基簇合衍生物的合成与表征

摘要

Through the reaction of Co 2(CO) 8 with four ligands containing P ?S? N atoms, cobalt carbonyl sulfur clusters Co 3(CO) 7( μ 3-S)〔 μ,η 2 -CNC(CH 3) 2P(S)(Cl)N(Ph)](Ⅰ)and Co 3 (CO) 7( μ 3-S)〔 μ,η 2 -SC(NH2)N-N=CH-C 6H 5〕 (Ⅱ),two tetranu-clear cobalt carbonyl clusters Co 4(CO) 10( μ 4 -S)( μ 4 -PC 6H 4OCH 3)(Ⅲ) and Co 4(CO) 10( μ 4-S)( μ 4-PC 6H 4OC 2H 5)(Ⅳ) ,were prepared and characterized by elementary analysis?IR? 1HNMR and MS spectroscopy.It was shown that bothⅠand Ⅱ have a tetrahedral framework Co 3S , both Ⅲ and Ⅳ have a octahedral framework Co 4SP. (Ⅰ)and Co 3 (CO) 7( μ 3-S)〔 μ,η 2 -SC(NH2)N-N=CH-C 6H 5〕 (Ⅱ),two tetranu-clear cobalt carbonyl clusters Co 4(CO) 10( μ 4 -S)( μ 4 -PC 6H 4OCH 3)(Ⅲ) and Co 4(CO) 10( μ 4-S)( μ 4-PC 6H 4OC 2H 5)(Ⅳ) ,were prepared and characterized by elementary analysis?IR? 1HNMR and MS spectroscopy.It was shown that bothⅠand Ⅱ have a tetrahedral framework Co 3S , both Ⅲ and Ⅳ have a octahedral framework Co 4SP.
