A New Wells-Dawson-based Organic-Inorganic Honeycomb Hybrid Compound with Cadmium Bis(2,2´-biimidazole) Spacers

A New Wells-Dawson-based Organic-Inorganic Honeycomb Hybrid Compound with Cadmium... A new Wells-Dawson-based organic-inorganic honeycomb hybrid compound, namely [Cd3(H2biim)6P2W18O62]·2H2O (1) (H2biim=2,2´-biimidazole), was hydrothermally synthesized by using a cadmium salt, the biimidazole ligand and the Wells-Dawson-type POM, and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. In compound 1, each polyoxoanion cluster [P2W18O62]6- is coordinated by six [Cd(H2biim)2]2+ subunits via six of its terminal oxygen atoms on two equatorial sites. Each [Cd(H2biim)2]2+ subunit links two adjacent polyoxoanions. Thus, the linking styles of the [P2W18O62]6- and [Cd(H2biim)2]2+ subunits induce a honeycomb-like layer. The electrochemical and photocatalytic properties of the title compound have been studied. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Zeitschrift für Naturforschung B de Gruyter

Abstract

A new Wells-Dawson-based organic-inorganic honeycomb hybrid compound, namely [Cd3(H2biim)6P2W18O62]·2H2O (1) (H2biim=2,2´-biimidazole), was hydrothermally synthesized by using a cadmium salt, the biimidazole ligand and the Wells-Dawson-type POM, and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. In compound 1, each polyoxoanion cluster [P2W18O62]6- is coordinated by six [Cd(H2biim)2]2+ subunits via six of its terminal oxygen atoms on two equatorial sites. Each [Cd(H2biim)2]2+ subunit links two adjacent polyoxoanions. Thus, the linking styles of the [P2W18O62]6- and [Cd(H2biim)2]2+ subunits induce a honeycomb-like layer. The electrochemical and photocatalytic properties of the title compound have been studied.
