title: Phosph(on/in)ate-bridged vanadium(IV) dimers: synthesis and characterization.
abstract: A series of dinuclear organophosphorus-bridged complexes of the general formula {(LVO(μ-O(2)PRR')}(2) [L = η(5)-cyclopentadienyltris(diethylphosphito-κ(1)P) cobaltate(III)] has been synthesized as a structural model for the industrially used vanadium phosphate oxidation catalysts. These dimeric species contain two vanadium centers in a VO(6) environment bridged by O-P-O units. These complexes have been characterized via spectral and magnetic analyses. Structural parameters have been analyzed through X-ray diffraction. The dimers generally exist in either a cis/cis-anti or retracted chair conformation in the solid state. The syntheses, structural, spectral, and magnetic data are presented and discussed here.
