A new molybdenum phosphate, (C2N2H10)(6)[Na2Mo12O31(PO4)(HPO4)(2)(H2PO4)(5)]center dot 4H(2)O has been synthesized under hydrothermal conditions and structurally determined by single-crystal X-ray diffraction method. It has the following crystal data: triclinic space group P-1, a = 12.0117(4) angstrom, b= 14.5565(5) angstrom, c=21.2805(8) angstrom, alpha= 80.6530(10), beta= 82.6410(10), gamma = 76.2610(10), V= 3550.8(2) angstrom(3), Z=2. The structure of the title compound may be considered to be two [Mo6O15(HPO4)(H2PO4)(3)](5-) units bonded together with sodium atom, although several P-O groups are not protonated on account of coordination to a Na+ cation. The one-dimensional tunnels were formed in the solid state structure. The structure is stabilized by template-to-framework hydrogen bonding. The title compound was also characterized by IR spectroscopy and TG-DTA. Luminescent measurement of the title compound shows an emission band between 724 and 747 nm when excited with 491 nm UV light.
