(Diethylenetriamine)(imidazole)(thiocyanato)copper(II) Perchlorate

The Cu atom in the title complex, [N-(2-aminoethyl-N)-1,2-ethylenediamine-N,N'](imidazole-N³)(thiocyanato-N)-copper(II) perchlorate, [Cu(NCS)(C₄H₁₃N₃)(C₃H₄N₂)]ClO₄, is coordinated in a trigonal bipyramidal arrangement by two primary N atoms of N-(2-aminoethyl)-1,2-ethylenediamine (diethylenetriamine) and one N atom of thiocyanate in equatorial positions, and by the `pyridine' N atom of imidazole and one secondary N atom of diethylenetriamine in axial positions. The Cu-N(imidazole) and Cu-N(thiocyanate) bond lengths are 1.978 (3) and 2.245 (4) Å, respectively.
