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.
