The synthesis and isolation of a hydrocarbon- and ether-insoluble organocopper compound containing the rigid 8-(dimethylamino)naphthyl group is described. An X-ray determination of its structure revealed a tetranuclear copper aggregate, in which the Cu atoms are arranged in a parallelogram (Cu…Cu 2.407(2) and 2.430(2) Å) and are three-center, two-electron bridged by C(ipso) (Cu-C 2.025(6) Å mean) of
