A series of three-coordinate bis(dialkylphosphinomethyl)benzo[c]phenanthrene Ag(I) complexes, alkyl= t-Bu, (1b), and cyclohexyl, (1c), anion = BF4, CIO4, CIO4, NO3, Cl, Br, I, have been prepared and thier 31P-NMR characteristics recorded. The solid state structures of [Ag(1b)Br], [Ag(1b)Cl] and [Ag(1b)CIO4] have been determined by X-ray diffraction. The Ag atom in these complexes shows distorted trigonal
一系列三配位的双(二烷基膦甲基)苯并[c]菲Ag(I)配合物,烷基= t- Bu,(1b)和环己基,(1c),阴离子= BF 4,CIO 4,CIO 4,NO制备图3的Cl,Br,I,并记录其31 P-NMR特性。[Ag(1b)Br],[Ag(1b)Cl]和[Ag(1b)CIO 4的固态结构通过X射线衍射测定。这些络合物中的Ag原子显示出扭曲的三角几何形状。选定的键长和角度如下:Ag-P = 2.463(4)Å和2.433(5)Å,在溴络合物中P-Ag-P = 141.6(2)°,Ag-P = 2.457(2)Å和2.427(2)Å,P-Ag-P = 142.6(1)°离子与氯配合物,Ag-P = 2.394(2)和2.393(2)Å,P-AG-P = 161.5(1)°在高氯酸盐复合物中。
