Two dinuclear oxovanadium(IV) compounds [V(O)(NMet)(μ-OMe)]2 · MeOH (1) and [V(O)(NThr)(μ-OMe)]2 · MeOH (2) were prepared by the reaction of VOSO4 and ONN donor ligands, HNMet and HNThr (HNMet =N-(2-pyridylmethyl)-dl-methionine, HNThr = N-(2-pyridylmethyl)-dl-threonine) derived from 2-pyridinecarbaldehyde and dl-methionine/dl-threonine. Both of these compounds are characterized by single crystal X-ray diffraction. X-ray crystallography revealed that the two vanadium(IV) compounds are both dinuclear structures bridged by methanol groups. Each vanadium atom is six coordinated in a distorted octahedral environment. IR spectroscopy and EPR spectra for these two compounds are also given.
Two dinuclear oxovanadium(IV) compounds [V(O)(NMet)(μ-OMe)]2 · MeOH (1) and [V(O)(NThr)(μ-OMe)]2 · MeOH (2) were prepared by the reaction of VOSO4 and designed amino acid derivatives ligands. The dimers were found to contain a planar [(OV)2O2] core consisting of methoxy-bridged trans-oxovanadium(IV) moieties. The ligands complete the distorted octahedral sphere of each oxovanadium(IV) moiety.Figure optionsDownload as PowerPoint slide
