在犤Co(2,3-tri)(men)Cl犦犤ZnCl4犦(2,3-tri=N-(2-氨乙基)-1,3-丙二胺;men=N-甲基乙二胺)体系中可能的几何异构体的数目多达二十个,其中经式异构体八个,面式异构体十二个。用单晶X-射线衍射分析方法解析了三个获得单晶的经式异构体,它们的晶体学参数:(1)m3-犤ZnCl4犦(monoclinicP21/c,a=8.0874(18),b=15.135(3),c=15.426(4)?,β=99.303(6)°,Z=4),(2)m4-犤ZnCl4犦(orthorhombicP212121,a=9.348(4),b=12.437(6),c=15.666(8)?,Z=4)and(3)m4’-犤ZnCl4犦(orthorhombicP212121,a=9.302(4),b=12.393(9),c=15.621(9)?,Z=4)。
(2,3-tri) (men) Cl 犦 犤 ZnCl4 犦 (2,3-tri = N- (2-aminoethyl) -1,3-propanediamine; men = N- Diamine) system up to twenty the number of possible geometric isomers, of which eight were the stereochemicals, the twelve areoforms. Three crystallographic isomers were obtained by single crystal X-ray diffraction analysis, and their crystallographic parameters were: (1) m3-犤 ZnCl4 monoc (monoclinicP21 / c, a = 8.0874 = 15.135 (3), c = 15.426 (4) ?, β = 99.303 (6) °, Z = 4), and m4- 犤 ZnCl4 犦 (orthorhombic P212121, a = 9.348 (4), b = 12.437 ), c = 15.666 (8) ?, Z = 4) and (3) m4’-? ZnCl4 ?, orthorhombicP212121, a = 9.302 (4), b = 12.393 (9), c = 15.621 = 4).
