with the copper(I) compounds, CuX (X = Cl, Br, I and SCN), in a 1:1 ratio to give 1:1 complexes, CuX(tcep), whereas it reacts with CuY (Y = PF 6 , ClO 4 , NO 3 , BH 4 , CN and CF 3 COO) in a 2:1 ratio to give the 2:1 complexes, CuY(tcep) 2 . Single crystal X-ray structures show that for the anions X = Br and SCN, the complexes are coordination polymers, [CuX(tcep)] n , with the Cu centres being bridged
摘要三(2-氰乙基)膦(tcep)与铜(I)化合物CuX(X = Cl,Br,I和SCN)以1:1的比例反应,生成1:1的配合物CuX(tcep) ,却以2:1的比例与CuY(Y = PF 6,ClO 4,NO 3,BH 4,CN和CF 3 COO)反应,生成2:1的配合物CuY(tcep)2。单晶X射线结构表明,对于X = Br和SCN的阴离子,络合物为配位聚合物[CuX(tcep)] n,其中Cu中心被阴离子桥接,每tcep具有一个腈臂配体与铜分子间配位,分别得到四面体“ PBr 2 N”和“ PSN 2”配位球。2:1化合物具有多种结构。对于Y = ClO 4,形成CN和CF 3 COO聚合物结构,但Y = BH 4除外,在该结构中,化合物为离散单体[Cu(BH 4)(tcep)2],与螯合阴离子和两个单齿P结合的tcep配体。由Y = CN和CF 3 COO获得的两种化合物也都含有
