摘要
配合物[Co(teta)(CN)_2](ClO_4)由 teta(teta=5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂环十四烷)、K[Ag(CN)_2]和 Co(ClO_4)_2·6H_2O 反应得到.测定了其晶体结构,晶体属单斜晶系,空间群是 C2/c,晶胞参数 a=2.159 7(9)nm,b=0.671 4(3)nm,c=1.865 9(8)nm,Z=4,R=0.056 8,wR=0.144 9.在配合物中,Co(Ⅲ)离子与四个氮原子和两个碳原子配位形成变形八面体构型,其中四个氮原子来自配体 teta,两个碳原子来自 CN-阴离子.
The title complex has been prepared by the reaction of teta (5,7,7,12,14,14- hexamethyl- 1,4,8,11-tetraazacylotetradecane), K lAg (CN) 2 ] with Co (ClO4) 2 · 6H2O. The X- ray crystal structure of [Co(teta)(CN)2](ClO4) has been presented. The complex crystallizes in the monoclinic, space group C2/c, a=2. 159 7(9) nm, b=0. 671 4(3) nm, c=1. 865 9(8) nm, Z=4, R=0.056 8 and ωR=0.144 9. The central Co(Ⅲ) ions octahedrally coordinated to four nitrogen atoms from teta and two carbon atoms from CN^- anion.
