cis-[Mn(CO)(4)(SePh)(2)](-) and cis-[Mn(CO)(4)(TePh)(2)](-), followed by a bezenselenolate ligand rearranging to bridge two metals and a labile carbonyl shift from Mn to Co, led directly to [(CO)(4)Mn(&mgr;-TePh)(2)Co(CO)(&mgr;-SePh)(3)Mn(CO)(3)]. Crystal data: triclinic space group P&onemacr;, a = 11.712(3) Å, b = 12.197(3) Å, c = 15.754(3) Å, alpha = 83.56(2) degrees, beta = 76.13(2) degrees, gamma = 72.69(2) degrees
二有机基二硒化物的氧化加成到不饱和配位的低价过渡金属羰基片段[Mn(CO)(5)](-)产生的顺式[Mn(CO)(4)(SeR)(2)] [ -)。在三斜晶空间群P&onemacr中结晶的顺式[PPN] [Mn(CO)(4)(SePh)(2)]络合物;其中a = 10.892(8)Å,b = 10.992(7)Å,c = 27.021(4)Å,alpha = 101.93(4)度,beta = 89.79(5)度,γ= 116.94(5)度,V = 2807(3)Å(3),Z = 2; 最终R = 0.085,R(w)= 0.094。顺式[Mn(CO)(4)(SeMe)(2)](-)的热转化为[(CO)(3)Mn(&mgr; -SeMe)(3)Mn(CO)(3)]( -)在室温下以高收率在THF中完成。[Na-18-crown-6-ether] [(CO)(3)Mn(&mgr; -SeMe
