Towards hydroperoxovanadium complexes: the X-ray crystal structure of a peroxovanadium(v) complex containing a V(O2)(RCO2H)(H2O)2 cluster with hydrogen bond inter-linkages

Abstract

The molecular structure of the oxo-peroxovanadium complex [VO(O₂)(bpaH)]ClO₄·2H₂O, containing the new ligand N,N-bis(2-pyridylmethyl)-β-alanine (bpaH) reveals tight binding of the carboxylic acid function to the vanadium centre through its doubly bonded oxygen; the carboxylic acid proton mediates hydrogen bonding interactions comprising the peroxo group and the two waters of crystallisation, thus providing the basis for the potential formation of a hydroperoxo species.
