用Syntex P3四圆衍射仪收集氯化邻乙氧羰基苯汞晶体的三维衍射数据。晶体属单斜晶系;空间群为(C_(2h)~5-P2_1/c;a=10.611(2)■,b=4.987(1)■,c=19.416(5)■,β=95.74(2)°;z=4。利用Patterson法和直接法测定了晶体结构。用块矩阵最小二乘法修正后,最终R值为0.044。晶体结构分析表明,在氯化邻乙氧羰基苯汞分子中存在有分子内配位,Hg…O(1)的间距为2.734■。
Three-dimensional diffraction data of o-ethoxycarbonylmercury chloride crystals were collected using a Syntex P3 four-circular diffractometer. The crystal is monoclinic; the space group is (C_ (2h) ~ 5-P2_1 / c; a = 10.611 (2) ■, b = 4.987 2) °; z = 4. The crystal structure was determined by the method of Patterson and the direct method, and the final R value was 0.044 after correction by the least square method of block matrix. The crystal structure analysis showed that in the o-ethoxycarbonylmercury chloride molecule There are intramolecular coordination, Hg ... O (1) spacing of 2.734 ■.
