Chlorido(2,2′-{[2-(1-methyl-1H-imidazol-2-yl-κN3)imidazolidine-1,3-diyl-κN]bis(methylene)}bis(1-methyl-1H-imidazole-κN3))copper(II) perchlorate

Abstract

In the crystal structure of the title complex, [CuCl(C17H24N8)]ClO4, the copper(II) metal exhibits an N4Cl pentacoordinate environment in a distorted square-pyramidal geometry. Coordination to the metal centre occurs through the three 1-methylimidazole N atoms from the pendant groups, one amine N atom from the imidazolidine moiety and one chlorido anion. Intermolecular interactions take place at two of the 1-methyl-imidazole rings in the form of parallel-displaced π–π stacking interactions forming chains parallel to the a axis. Three O atoms of the perchlorate anion are rotationally disordered between two orientations with occupancies of 0.5.
