Di-μ-chloro-bis[(diethylenetriamine)copper(II)] Dinitrate

The crystal structure of the title compound, di-μ-chloro-bis{[N-(2-aminoethyl)-1,2-ethanediamine-N,N′,N′′]copper(II)} dinitrate, [Cu₂Cl₂(dien)₂](NO₃)₂ (dien is diethylenetriamine; C₄H₁₃N₃), consists of chloride-bridged copper(II) dimers. Each copper ion is five coordinate with geometry that is approximately square-pyramidal. Hydrogen bonding involving the three O atoms of the nitrate counteranions and the three H atoms of the amine groups of the organic ligand stabilizes the crystal packing.
