cze	Synthesis, Characterization and Structure of the Bis(methyl-cyclopentadienyl)vanadium(IV) Carboxylates	The 1,1'-dimethylvanadocene dichloride ((C5H4CH3)2VCl2) reacts in aqueous solution with various carboxylic acids giving two different types of complexes. The 1,1'dimethylvanadocene complexes of monocarboxylic acids (C5H4CH3)2V(OOCR)2 (R = H, CCl3, CF3, C6H5) contain two monodentate carboxylic ligands, whereas oxalic and malonic acids act as chelate compounds of the formula (C5H4CH3)2 V(OOC-A-COO) (A= -, CH2). The structure of the (C5H4CH3)2V(OOCCF3)2 complex was determined by single crystal X-ray diffraction analysis. The isotropic and anisotropic EPR spectra of all the complexes prepared were recorded. The obtained EPR parameter values were found to be in agreement with proposed structures.	vanadocene
