Abstract

Full title: Investigations of the vanadium-oxo-organophosphonato system: Preparation and structural characterization of a mixed-valence V^V-V^IV cluster encapsulating chloride anions, (Bu₄N)₂[(V ₈O₁₆){V₄O₄(H₂O) ₁₂}(PhPO₃)₈Cl₂]·2Et ₂O·2MeOH·4H₂O. The reaction of (Bu₄N)[V₅O₇(OMe) ₂(PhPO₃)₅] with aqueous HCl in methanol followed by treatment with diethyl ether yields dark brown crystals of (Bu ₄N)₂[(V₈O₁₆){V₄O ₄(H₂O)₁₂}(PhPO₃)₈Cl ₂]·2Et₂O·2MeOH·4H₂O 1, a mixed-valence V^V-V^IV cluster consisting of two (V ₄O₈)⁴⁺ caps each bridged through four PhPO ₃^2- groups to a central girdle of four [VO(H ₂O)₃]²⁺ units, and encapsulating two chloride anions in the molecular cavity.
