Zinc Bis[mu-N,N '-chlorozinc-bis(N-trimethylsilyliniino-diphenylphosphoranyl)-methanediide ]: A zinc derivative of a gentinal carbdianion

摘要

The trinuclear title compound, C74H88Cl2N4P4Si4Zn3, is derived from a geminally substituted carbdianion. The central zinc atom shows a nearly linear coordination geometry with very short Zn-C bond lengths (average 191 pm). The peripheral metal centers of the chlorozinc moieties are chelated by the phosphanimine donors and hence are triply coordinated, thus forming a six-membered CP2N2Zn ring with Zn-N distances of 195 pm (average).
