Abstract The structure of trans -[CrCl 2 (NH 2 Et) 4 ]Cl (monoclinic, I2/a, a = 15.163(5), b = 6.458(2), c = 16.652(4) A , β = 92.51(2)°, V = 1629.0(8) A 3 , Z = 4 has been determined. The two CrCl bonds are symmetry related (CrCl = 2.323(1) A) and two of the ( cis ) EtNH 2 ‘arms’ are above and two are below the Cr(N) 4 plane. The Hg 2+ -assisted chloride release from trans -[CrCl 2 (NH 2 R) 4 ] + occurs
