摘要：

本文报道了Cu(Ⅱ)的吡唑和硫氰酸根混合配体配合物[Cu(pz)4(NCS)2](1)(pz=吡唑)的合成、晶体结构及性质.配合物属单斜晶系,C2/c空间群,a=1.1520(4) nm,b=1.2247(4) nm,c=1.4188(5), β=106.747(8)°, Z=4, R1=0.0554, wR2=0.1420.配合物中Cu(Ⅱ)与4个吡唑环上的4个N原子及2个NCS-的N原子配位形成4+2型拉长八面体配位环境,4个吡唑环上的N原子占据赤道位置, 2个NCS-的N原子占据轴向位置.对配合物的IR、UV-Vis、ESR进行表征和分析.比较不同轴向配体对结构和性质的影响.

关键词: Cu(Ⅱ)配合物, 吡唑, 硫氰酸根, 晶体结构, 性质

Abstract:

This paper presents the synthesis, crystal structure and properties of copper(Ⅱ) complex[Cu(pz)4(NCS)2](pz=pyrazole). The complex was crystallized in the monoclinic system, space group C2/c, a=1.1520(4) nm, b=1.2247(4) nm, c=1.4188(5) nm, β=106.747(8)°, Z=4, R1=0.0554,wR2=0.1420. The Cu(Ⅱ) ion is in 4+2 environment with an elongated-octahedron geometry. The basal plane of the central copper atom is formed by the four pyrazole nitrogen atoms and the apical positions are occupied by two nitrogen atoms of two NCS- anions. IR, UV-Vis and ESR spectra were also measured and the results are well consistent with the crystal structure.

Key words: copper(Ⅱ) complex, pyrazole, thiocyanate, crystal structure, properties
