Dichlorido(dimethyl-formamide-κO)[1,4,7-tris-(2-cyano-ethyl)-1,4,7-triaza-cyclo-nonane-κN,N,N]cobalt(II).

The title compound, [CoCl(2)(C(15)H(24)N(6))(C(3)H(7)NO)], crystallizes as a monomeric complex. The coordination environment around the Co(II) center could be described as a distorted octa-hedron consisting of three N donors from the facially coordinating triaza macrocyclic ligand, one O donor from dimethyl-formamide and two Cl(-) ions. Neutral complex mol-ecules are associated via inter-molecular C-H⋯Cl hydrogen bonds to form two-dimensional layers. C-H⋯O hydrogen bonds are also present.
