Stereochemical Features of Five-Coordinate Dimeric Square Pyramidal Oxovanadium (IV) Complexes
Journal Title: Saudi Journal of Medical and Pharmaceutical Sciences - Year 2016, Vol 2, Issue 8
Abstract
Abstract: Due to their hard nature, the oxvandium (iv/v) ions have a good affinity towards O,N, donor ligands. The interaction of UO2+with hydroxy carboxylic acid is also important because of their varied geometries. The vanadium atoms in the complexes are hex-coordinated and the coordination sphere is of the type [vo(oo) (NN)] where o-atoms are of oxo, carboxylic and phenolic type and N-atoms are of pyridine type. The sixth coordination position site is occupied by phenolic oxygen of neigh-bouring molecule forming a bridge, the (V=O) confirms, the hexa coordination. All the complexes have dxy' type axial EPR spectra and they exhibit two Ligand field transition at 740 and 440 mm.
