Abstract

Reaction of the dilithium salt of tripyridyldiamine, Li2tpda, and CrCl2 in THF gave the pentachromium compound Cr5(tpda)4Cl2·CH2Cl2 in which the metal atoms were arranged in a linear fashion with localized quadruple bonds Cr[quadruple bond, length as m-dash]Cr  · · · Cr[quadruple bond, length as m-dash]Cr · · · Cr.
