Three geometrical meridian isomers of [Co(2,3-tir)(amp)Cl]ZnCl4(2,3- tri=N-(2-aminoethyl)-1,3- propanediamine; amp=2-(aminomethyl)pyridine) were synthesized and isolated. The crystal structures of two title complexes were determinated. The third complex remaining in solution wes charactelized by 2D NMR techniques including DQCOSY and NOESY. The two geometrical isomers, which were enantiomers to each other and existed in a 1:1 ratio, were proven to be the meridian isomer, based on the centricspace groups.
