Hydrothermal synthesis, crystal structure and electrochemical property of a novel 3-D microporous reduced molybdophosphate with large cavities

A novel molybdenum phosphate based on [Mo6P4] inorganic subunits and [Mn(H2O)2]2+ cations, Mn[Mo6O12(OH)3(PO4)(HPO4)2(H2PO4)]2[Mn(H2O)2]2(Hen)4·13H2O (en = ethyl enediamine), has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction, IR spectroscopy, EPR spectrum and TGA analysis. The 3-D framework of the compound contains microporous structure with large cavities filled by mono-protonated Hen+ and water molecules. The electrochemical behavior of the compound has been also studied.

The synthesis and structural characterizations of a 3-D reduced molybdenum phosphate based on Mn[Mo6P4] inorganic moieties and [Mn(H2O)2]2+ coordinated cations with large cavities (the voids constitute 23% of the volume of the solid), Mn[Mo6O12(OH)3(PO4)–(HPO4)2(H2PO4)]2[Mn(H2O)2]2 (Hen)4·13H2O (en = ethylenediamine), are presented in this communication. The electrochemical behavior of the compound has been also studied.Figure optionsDownload as PowerPoint slide
