The structure of 2,3,7,8,12,13,17,18-octaethylporphinatooxovanadium(IV) has been determined from three-dimensional x-ray diffraction data. The complex crystallizes in the monoclinic space group C2h5-P21/c with four molecules in a unit cell of dimensions a = 14.334 (3), b = 23.061 (8), c = 9.815 (2) Å, β = 104.18 (2)°. The structure was solved by direct methods. Least-squares refinement has led to a final value of the conventional R index (on F02) of 0.084 based on 6482 reflections (including F02 ≤ 0). The vanadium atom is found to be 0.543 Å above the plane of the four nitrogen atoms. The average V-N bond distance is 2.102 (6) and the V-O bond length is 1.620 (2) Å. The porphyrin itself is slightly nonplanar.
