Two new NiII complexes with μ1,5-dicyanamide as bridging ligand

Two μ1,5-dca (dca = dicyanamide anion) bridged NiII coordination polymers with two different open chain diamines, 4-(2-aminoethyl)-morpholine and 1-(2-aminoethyl)-piperidine, have been synthesized and characterized by X-ray single crystal structure determination. Variable temperature magnetic behaviors have also been studied.
