Synthesis & structure of copper complex (N_3)_2

The mononuclear copper complex with the ligand 1,4,7-triazacyclononane was synthesized and its structure was determined by single crystal X-ray analysis.The crystal is monoclinic ,space group P2(1)/n,the copper(Ⅱ)ion is coordinated by five nitrogen atoms of the two kind of ligands and forms a slightly transformed pyramid.
