Abstract: 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 P21/c,a=8.0874(18),b=15.135(3),c= 15.426(4)?,β=99.303(6)°,Z=4), for (2)m4-[ZnCl4](orthorhombic P212121,a=9.348(4),b=12.437(6),c=15.666(8)?,Z=4) and for (3)m4′-[ZnCl4](orthorhombic P212121,a= 9.302(4),b=12.393(9),c=15.621(9)?,Z=4). |
