Herein, first examples of supramolecular hybrid organic-inorganic cluster-porphyrin [ CP n ( n = 2, 6)] systems constructed via metal-ligand coordination have been reported. The pyridine end-decorated Mo( ii ) halide cluster ((Bu 4 N) 2 [{Mo 6 I 8 }(OOC-C 5 H 4 N) 6 ]), possessing remarkable photophysical properties, was chosen as the inorganic part and A 2 -type zinc porphyrin 5,15-bis[( p -tolyl)porphyrinato(2-)]zinc was selected as the organic part. The crystal structures of CP 2 and CP 6 hybrids have been characterised by single crystal X-ray diffraction. The CP 2 complex is composed of two zinc porphyrins, coordinated to pyridyl moieties of the same cluster molecule, related by an inversion center. In the case of the CP 6 complex, each cluster has three pairs of coordinated symmetrically equivalent zinc porphyrins. Also, the formation of supramolecular hybrid CP n ( n = 2, 6) systems was unambiguously demonstrated in solution via NMR and UV-Vis spectroscopy titration and diffusion ordered NMR spectroscopy (DOSY). Herein, first examples of supramolecular coordination bonded hybrids of Mo( ii ) cluster and zinc( ii ) porphyrinates are reported.
