Dichlorido(dimethylformamide-κO)[1,4,7-tris(2-cyanoethyl)-1,4,7-triazacyclononane-κ3N1,N4,N7]nickel(II)

Abstract

The title complex, [NiCl2(C15H24N6)(C3H7NO)], is isomorphous with the CoII analogue. Three N-atom donors from the facially coordinating triaza macrocyclic ligand, one O-atom donor from dimethylformamide and two Cl− anions surround the NiII ion in a distorted octahedral coordination geometry. Intermolecular C—H...Cl and C—H...N hydrogen-bonding interactions link the complex molecules into a three-dimensional supramolecular architecture.
