Syntheses, Structures, and Luminescence Properties of New Octahedral Cluster Complexes with Terminal Phenolate Ligands: [K(H2O)(CH3OH)3]2[Ph4P]2[M6Cl12(O–C6H4–F)6] (M = Nb, Ta; Ph = phenyl)

The cluster compounds [K(H2O)(CH3OH)3]2[Ph4P]2[M6Cl12(para-O–C6H4–F)6] (M = Nb (1), Ta (2); Ph=phenyl) were obtained by the reaction of [Nb6Cl14(CH3OH)4]·6 CH3OH with potassium p-fluorophenolat and tetraphenylphosphonium chloride. 1 and 2 were crystallized from CH3OH and characterized by X-ray single-crystal diffraction, IR-,1H NMR-,UV–Vis- and luminescence spectroscopy.
