Diisocyanoarene-linked pentacarbonylvanadate(I−) ions as building blocks in a supramolecular charge-transfer framework assembled through noncovalent π–π and contact ion interactions

Abstract

Three synthetic routes to the unusual supramolecular complex ([Cp₂Co]₂[{(OC)₅V}₂(μ-1,4-CNC₆Me₄NC)])_∞, which was crystallographically characterized, are presented. The dianion [{(OC)₅V}₂(μ-1,4-CNC₆Me₄NC)]²⁻ constitutes the first subvalent organometallics featuring a diisocyanoarene linker.
