Triorganotin, triorganolead and tetraphenylantimony derivatives of acetylenedicarboxylic acid (H2ADC), terephthalic acid (H2TER) and dithioterephthalic acid (H2DTT) (R3M)2X (M = Sn, Pb; R = Me, Ph; X = ADC, TER, DTT) and (Ph4Sb)2X (X = ADC, TER) were prepared by neutralization of R3MOH or Ph4SbOH with the appropriate acid (X = ADC, DTT) or by reaction of R3MCl or Ph4SbCl with K2TER. The crystal structures
乙炔二羧酸(H 2 ADC),对苯二甲酸(H 2 TER)和二硫代对苯二甲酸(H 2 DTT)(R 3 M)2 X的三有机锡,三有机油和四苯基锑衍生物(M = Sn,Pb; R = Me,Ph; X = ADC,TER,DTT和(Ph 4 Sb)2 X(X = ADC,TER)通过用适当的酸(X = ADC,DTT)中和R 3 MOH或Ph 4 SbOH或通过与R 3 MCl或带有K 2 TER的Ph 4 SbCl 。(Me 3 Sn)2 ADC和(Me 3 Sn)2的晶体结构TER通过X射线衍射测定。Sn原子处于稍微变形的三角双锥体环境中,C(Me)位于赤道平面,O(羧基)位于顶端。羧酸酯基桥接,导致形成折叠的22元[(Me 3 Sn)2 ADC]和26元[(Me 3 Sn)2 TER]环的二维聚合物。从振动光谱推断出固体(Ph 3 Sn)2 ADC,(R 3 Pb)2 ADC(R = Me,Ph)和(Me
