The reaction of trans-[CoCl2(2,3,2-tet)]+(2,3,2-tet: 3,7-diazanonane-1,9-diamine) with (2-aminoethyl)dimethylphosphine (edmp) afforded only one geometrical isomer of [Co(edmp)(2,3,2-tet)]3+, the structure of which was determined by X-ray analysis to have the cis-β,trans-(sec-N,P) configuration.
反式-[CoCl2(2,3,2-tet)]+(2,3,2-tet: 3,7-diazanonane-1,9-diamine) 与 (2-aminoethyl)二
甲基膦 (edmp) 反应得到[Co(edmp)(2,3,2-tet)]3+ 只有一种几何异构体,其结构经 X 射线分析确定为顺-β,反-(sec-N,P)配置。
