Abstract

The reaction of VOBr₂ with N,N,N'N'-tetrakis(2-pyridylmethyl) ethylenediamine (tpen) and NaH₂PO₄ (2:1:2 molar ratio) in an aqueous/ethanolic solution yielded purple crystals. X-ray crystal structure analyses revealed that the purple complex was a dinuclear vanadium(IV) complex bridged by a diphosphate anion, [(V^IVO)₂(μ-P ₂O₇)(μ-tpen)].10H₂O. This indicates that a condensation reaction occurred between two phosphate ions during the reaction to form a phosphatephosphate bond. A probable mechanism is proposed for the condensation reaction of two phosphate anions.
