摘要：
A new organic-inorganic hybrid compound (2-AMP)(4)[Se2Mo5O21]center dot 2H(2)O (1) [2-AMP = 2-aminopyridinium] has been synthesized and characterized by IR spectrum, UV-Vis spectra, H-1 NMR spectroscopy, thermogravimetric analyses, cyclic voltammetry measurements and single crystal X-ray diffraction. Compound 1 crystallizes in the triclinic system with space group P-1 and a = 11.451(6) , b = 13.478(3) , c = 14.037(2) , alpha = 108.956(2)A degrees, beta A = 96.260(2)A degrees, gamma A = 97.174(3)A degrees, Z = 2. The title compound contains four protonized 2-AMP cations, five distorted MoO6 octahedra and two SeO3 pyramids by sharing vertices and edges. These five Mo atoms are nearly coplanar, and two SeO3 pyramids lie on both sides of this plane. The interactions between [Se2Mo5O21](4-) clusters are established through hydrogen contacts which involve selenium, water molecules and 2-aminopyridine cations to form a three-dimensional structure.
