| 摘 要： | 我们对六次甲基四胺(HMT)加合物的研究早感兴趣。为探讨Sommelet反应机理,我们证实氯化苄与HMT加合物为季胺盐阳离子(CH_2)_6N_4·CH_2C_6H_5]~ 与Cl~-交错堆积组成的离子晶体。晶体中与四配位N联结的C-N键长有明显的增长效应。本文为其平行的工作。实验HMT与溴代丙烯加合物晶体的制备0.8g HMT溶于30 mL 1∶1三氯甲烷-丙酮,滴入0.7mL溴丙烯,待有细小晶体析

| Abstract: | ((CH2)6N4.CH2CHCH2)+Br- is an orthogonal ionic crystal. The crystal data are: Pmnb, a = 6.602(2)A, b = 12.184(4)A, c = 14.499(6)A, V = 1166A3, Mr = 261.2, Z = 4, Dc = 1.49Mgm*-3, F(000) = 536. The N(1) of HMT Directly bonds to the C(5) of (CH2CHCH2)+ with δ donoracceptor bond. The four C-N distances connected with N(1) are longer than the normal C-N single bond length. C(7) is disordered over two sites and both siteoccupation factors of C(7) and C(7)' are 0.5. The relation of the disorder structure with the molecular packing and the molecular conformation was discussed. |
