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)。

Among the twenty isomeric forms which are possible for [Co(2, 3-tri) (men) Cl] [ZnCl4] system (2, 3-tri = N-(2-Aminoethyl) -1, 3-propanediamine; men = N-methylethylenediamine), the structures of three mer-isomers have been determined by single crystal X-ray diffractions, crystal data: for (1) m3-[ZnCl4] (monoclinic P2(1)/c, a = 8.0874 (18), b = 15.135 (3), c = 15.426 (4) Angstrom, beta = 99.303(6)degrees, Z = 4), for (2) m4-[ ZnCl4] (orthorhombic P2(1)2(1)2(1), a = 9.348 (4), b = 12.437 (6), c = 15.666(8) Angstrom, Z = 4) and for (3) m4'-[ ZnCl4] (orthorhombic P2(1)2(1)2(1), a = 9.302 (4), b = 12.393 (9), c = 15.621(9)Angstrom, Z = 4).
