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.
