Two geometric isomers of a new [Co(bamp)(cmen)Cl]ZnCl 4 system were synthesised by decomposing per-oxide complex, here bamp = 2,6-(Aminomethyl)pyridine; cmen = 1,2-diaminopropane. The crystal structure of an isomer (m1ZnCl 4) was determined by Rigaku AFC7R. The crystal structure belongs to monoclinic with space group C2/c, a = 2.0120(6)nm, b = 0.9408(3)nm, c = 2.0521(6)nm, β = 92.045(6)°, V = 3.8822(19)nm 3, Dc = 1.786g/cm 3, Z = 8, F 000 = 2104, μ(Mo Kα)= 27.83cm -1 , R = 0.0426, Rw = 0.1038. There are four complex cations which are enantiomers with a ratio of 1:1 in a unit cell.
