Four novel organic鈥搃norganic hybrid materials of the copper(II)鈥搈olybdophosphonate family, [Cu(1,10-phen)Mo₂O₅(H₂O)(hedp)] (1), [{Cu(1,10-phen)}{Cu(1,10-phen)(H₂O)}MoO₂(hedpH)₂]路H₂O (2), [Cu(1,10-phen)Mo_0.5O(hedpH)] (3), and [{Cu(2,2鈥?bipy)(H₂O)}MoO₂(hedp)]路2H₂O (4) (hedpH₄ = 1-hydroxyethylidenediphosphonate, 2,2鈥?bipy = 2,2鈥?bipyridine, 1,10-phen = 1,10-phenanthroline), have been synthesized under hydrothermal conditions. In compound 1, the interconnection of {MoO₆}, {CuN₂O₂}, and {CPO₃} polyhedra leads to a 2D layer through edge-sharing and corner-sharing, and such layers are further assembled into a 3D supramolecular structure by 蟺鈥撓€ stacking interactions. Compound 2 contains a 1D chain built up from {MoO₆}, {CuN₂O₃}, and {CPO₃} polyhedra, and then these 1D chains are further extended into 2D supramolecular layer by hydrogen bonding interactions. Such neighboring layers are further assembled into a 3D supramolecular structure via the 蟺鈥撓€ stacking interactions. For compound 3, the [{Cu(1,10-phen)}₂MoO₂(hedpH)₂] units are interlinked by hydrogen bonds interactions to give a hydrogen bonded double chains. The neighboring chains are further assembled through 蟺鈥撓€ stacking interactions to form a 3D supramolecular structure. In compound 4, the interconnection of {MoO₆}, {CuN₂O₃} and {CPO₃} polyhedra via corner-sharing forms a 1D chain. These 1D chains are interlinked through hydrogen bonding interactions to form a 2D supramolecular layer, which are further assembled into a 3D supramolecular structure via the 蟺鈥撓€ stacking interactions. Surface photovoltage properties of the four compounds have also been studied.
