Abstract The dinuclear compound, 1, with the molecular formula of [Cu2(H3L)2(ClO4)2][Cu2(H3L)2(MeCN)2](ClO4)6 was prepared by the reaction of [bis-(1H-imidazol-2-yl)-methyl]-pyridin-2-yl-methylamine (H3L) with copper(II) perchlorate. The asymmetric unit of the crystalstructure of 1 contains two dinuclear units, [Cu2(H3L)2(ClO4)2]2+ and [Cu2(H3L)2(MeCN)2]4+ (abbreviated as 1ClO4 and 1MeCN), respectively
