A series of tris(N,N-dialkylcarbamato)antimony(III) complexes, Sb(O(2)CNR(2))(3) (R = Me, Et, Pr(i)()), have been synthesized and are the first members of this class of compound to have been crystallographically characterized. Sb(O(2)CNMe(2))(3) (1) exists as a weakly bound dimer, whereas its diethyl and diisopropyl analogues (2, 3) are monomeric. In addition, tetrakis(N,N-diethylcarbamato)tin(IV)
合成了一系列三(N,N-二烷基氨基甲酸酯)锑(III)配合物Sb(O(2)CNR(2))(3)(R = Me,Et,Pr(i)()),并是在晶体学上表征的这类化合物的第一批成员。Sb(O(2)CNMe(2))(3)(1)以弱结合的二聚体形式存在,而其二乙基和二异丙基类似物(2,3)是单体。此外,已准备好四(N,N-二乙基氨基甲酸酯)锡(IV)(4)进行比较,并通过单晶X射线分析显示其具有相对罕见的SnO(8)配位。晶体学数据:对于1,a = 8.7520(5)A,b = 14.2970(8)A,c = 11.8150(7)A,beta = 108.029(2)度,单斜度,P2(1)/ c,Z = 4 ; 对于2,a = b = 14.4690(2)A,c = 16.6740(2)A,三角形,Rthremacr ;, Z = 6; 对于3,a = 11.9881(2)A,b = 11.6521(3)A,c
