摘要：

Reaction of CrCl2 and Li[(o-ClC6H4N)(2)CH] in THF gives Cr-2[(o-ClC6H4N)(2)CH](3)(mu-Cl). This compound has three bridging formamidinates and a bridging chlorine atom. The resulting A-frame is the first having a quadruply bonded M-2(4+) unit. The Cr-Cr distance of 1.940(1) Angstrom is in the normal range for a short quadruple bond. (C) 1999 Elsevier Science S.A.
