摘要
用过氧化物法合成了 [Co(2,3 tri)(amp)Cl]ZnCl4( 2,3-tri =N-(2-Aminoethyl)-1,3-propanediamine; amp=2-(Aminomethyl)pyridine)中的四个异构体,解析了其中的一个几何异构体的晶体结构:顺式( 2,3-tri中仲胺上的氢相对于 Cl)经式异构体 (m4)。晶体学参数:单斜晶系,空间群 P21/c, a=12.025(3)?, b=9.792(2)?, c=16.912(2)?,β =93.70(1)°, V=1987(2)? 3, Dc=1.761g· cm- 3, Z=4, F000=1064.00,μ (MoKα )=27.17 cm- 1, R=0.030, Rw=0.038。配合物离子中 Co3+为六配位。晶胞中含 4个配合物离子,对映体的比例为 1∶ 1。
Four geometric isomers of a new [Co(2,3- tri)(amp)Cl]ZnCl4 system were synthesised by decomposing per oxide complex,here 2,3 tri=N (3 Aminoethyl) 1,3 propanediamine; amp=2 (Aminomethyl)pyridine. The crystal structure of an isomer (m4) was determined by Rigaku AFC 7R. The crystal structure belongs to monoclinic with space group P21/c,a=12.025(3)? ,b=9.792(2)? , c=16.912(2)? ,β =93.70(1)° ,V=1987(2)? 3,Dc=1.761g· cm- 3,Z=4,F000 =1064.00,μ (MoKα )=27.17cm- 1,R=0.030,Rw=0.038. There are four complex cations which are enantiomers with a ratio of 1∶ 1 in a unit cell.
