Abstract: The title compound, [Mo(C36H44N4)O]2[Mo6O19], contains a five-coordinate molybdenum-porphycene cationic complex, accompanied by a centrosymmetric hexamolybdate counter-anion. This is the first structure for a molybdenum porphycene. The shape of the central N4 cavity is rectangular, enlarged lengthwise by metal coordination, and the mean short and long NN distances defining the N4 cavity are 2.582 (9) and 3.031 (9) Å, respectively.
