Free and coordinated biarsolyls

Abstract

A trace side product from the reaction of [Mo(AsC4Me4)(CO)3(η-C5H5)] with [Mn(THF)(CO)2(η5-C5H4Me)] was identified as the biarsolyl complex [Mn2{μ-(AsC4Me4)2}(CO)4(C5H4Me)2] on the basis of a strategic synthesis from [Mn(THF)(CO)2(η5-C5H4Me)] and the pre-formed and structurally characterised biarsolyl (AsC4Me4)2. Crystallographic and computational data for this first example of a biarsolyl complex and free biarsolyls are discussed in the context of those for free biarsolyls. Show more
