Cocrystallization of dichloro(N,N-dimethylformamide)[hydrotris(pyrazol-1-yl)borato]vanadium(III) with its partially oxidized analog chloro(N,N-dimethylformamide)[hydrotris(pyrazol-1-yl)borato]oxovanadium(IV)

Abstract: The components dichloro(N,N-dimethylformamide)[hydrotris(pyrazol-1-yl)borato]vanadium(III), [TpVCl₂(DMF)], and its partially oxidized analog chloro(N,N-dimethylformamide)[hydrotris(pyrazol-1-yl)borato]oxovanadium(IV), [TpVOCl(DMF)], cocrystallize in an approximately 1:1 ratio, viz. [V(C₉H₁₀BN₆)Cl₂(C₃H₆NO)][V(C₉H₁₀BN₆)ClO(C₃H₆NO)]. The components both exist in the solid state with disorder of the Cl/O site and with V in a pseudo-octahedral coordination geometry. The complexes each have three pyrazole units of the hydrotris(pyrazol-1-yl)borate ligand bound to one `face' of the vanadium center and one chloro, one oxo/chloro, and one oxo-bound N,N-dimethylformamide ligand bound to the other face.
