Dibromido[(1R,2R,N 1 S)-N-(pyridin-2-ylmeth­yl)cyclo­hexane-1,2-diamine-κ3 N,N′,N′′]cadmium

In the title compound, [CdBr(2)(C(12)H(19)N(3))], the Cd(II) atom is coordinated by the three N atoms of the (1R,2R)-N-(pyridin-2-ylmeth-yl)cyclo-hexane-1,2-diamine ligand and a bromide ion in the basal plane, and by a second bromide in the apical position. The coordination environment can be described as distorted square pyramidal. The coordination of the enanti-o-pure ligand to the metal atom renders the central N atom chiral with an S configuration, so the complex is enanti-omerically pure and corresponds to the S,R,R diastereoisomer. In the crystal, the mol-ecules are linked via weak N-H⋯Br hydrogen bonds into a chain parallel to the b axis.
