Dichloro-μ₂,μ₂-naphthalene-1,8-diyl-bis(<i>N</i>,<i>N</i>,<i>N</i>′,<i>N</i>′-tetramethylethylenediamino)tetracopper(I)

Abstract

A highly reactive dicuprate/CuCl aggregate, Nap(Cu4Cl2)(TMEDA)2 (2, Nap = naphthalene-1,8-diyl, TMEDA = tetramethylethylenediamine), was synthesized by the reaction of 1,8-dilithionaphthalene(TMEDA)2 with four equivalents of CuCl. The X-ray crystal structure of this complex shows that the four copper atoms form a bent parallelogram-shaped core, with terminally bonded chlorine atoms. The naphthalene ring is bonded through carbons in the 1 and 8 positions (peri-positions), each bridging two copper atoms.
