本文报道标题化合物[Cu(phenNO)_2(H_2O)_2](NO_3)_2的合成及其晶体结构。该晶体属单斜晶系,空间群为C2/c,Z=4,晶胞参数:a=15.724(2),b=8.995(2),c=18.432(3),β=112.06(2)°。可观测的独立反射点数目为2352个。晶体结构利用直接法与Fourier合成法得到。经全矩阵最小二乘法修正,最后的R=0.077。结构分析表明,铜与配体的2个氧、2个氮以及2个水分子中的氧配位,配位的几何构型为稍显扭曲的拉长八面体。

In the present work, we describe the synthesis and crystal structure of the title compound. The complex crystallizes in the monoclinic space group C2/c with Z=4. Lattice parameters are: a= 15. 724 (2) A, b=8. 995(2) A, c=18. 432(3) A ,β= 112. 06(2)°. The structure was solved by the direct method and Fourier techniques and refined by full-matrix least-squares to R= 0. 077 for 2352 reflections. The Cu2+ ion is six-coordinate, being bonded to two oxygen atoms, two nitrogen atoms belong to two ligands and two oxygen atoms belong to two water molecules; The coordinated configuration of Cu2+ ion is a slightly distorted octahedron. The nitrate groups are not coordinated to Cu2+ ion.
