The compounds Ca[Cu(5′-GMP)2(en)(H2O)2]·8H2O(1) and Ca[Cu(5′-IMP)2(H2O)4]·6.7H2O(2) have been prepared and their structures determined (5′-GMP = guanosine 5′-monophosphate, en = ethylenediamine, and 5′-IMP = inosine 5′-monophosphate). Crystals of (1) are monoclinic space group P21, with a= 10.997(2), b= 21.693(4), c= 8.872(2)Å, β= 94.69(l)°, and Z= 2. Crystals of (2) are orthorhombic, space group C2221
化合物Ca [Cu(5'-GMP)2(en)(H 2 O)2 ]·8H 2 O(1)和Ca [Cu(5'-IMP)2(H 2 O)4 ]·6.7H已制备2 O(2)并确定了它们的结构(5'-GMP =鸟苷5'-单磷酸,en =乙二胺,5'-IMP =肌苷5'-单磷酸)。(1)的晶体是单斜晶空间群P 2 1,其中a = 10.997(2),b = 21.693(4),c = 8.872(2)Å,β= 94.69(l)°,Z = 2。的(2)是斜方晶系,空间群Ç 222 1,具有一个= 8.757(2),b = 23.229(5),C ^ = 21.212(5),和ž = 4这两种结构是由重原子技术解决,精制通过全矩阵最小二乘法计算以[R = 0.074和- [R '= 0.064 1个266反射为(1)和- [R = 0.094和- [R '= 0.093 1个275反射为(2)。在这两个结
