Abstract: The synthesis, EPR (electron paramagnetic resonance) characterization, and crystal structure of (C₁₆H₃₆N)₂[VO(C₃H₂O₄)₂] are described. The V atom is pentacoordinated by an oxo and two bidentate malonate ligands. The geometry around the metal is square-pyramidal and the two bidentate malonate ligands form the base of the pyramid. The V=O bond length is 1.556  (3)  Å and the range of V-O bond lengths is 1.960  (3)-1.968  (3)  Å. The EPR spectrum (g_iso = 1.965 and A_iso = 0.00965  cm^-1) is typical of a V^IV system.
