Among the large variety of organic compounds porphyrins are promising candidates for hybrid supramolecular systems due to the rich chemical and photophysical characteristics. Halide Mo(II) clusters also possess remarkable photophysical properties and could be used as inorganic part. Herein we report the design, synthesis and structural features of supramolecular hybrid organic-inorganic cluster-porphyrin systems bonded via metal-ligand coordination. The zinc(II) 5,15-di(tolyl)porphyrinate (P) was used as an organic part and the octahedral pyridine end-decorated Mo(II) halide cluster [(Mo6I8)(PyCOO)6][Bu4N]2 (C) as inorganic. The formation of the CPn (n=2, 6) systems via NPy...Zn axial coordination was investigated both in solid state and in solution. The crystal structures of CPn (n=2, 6) were determined by X-ray structural analysis. The supramolecular association in solutions (CDCl3, CH2Cl2) was investigated by UV-Vis titration, 1H NMR and DOSY measurements. Our approach may open the way for the creation of a new family of hybrid systems exhibiting interesting photophysical properties.
