Abstract：

The　title　compound　was　synthesized　under　hydrothermal　condition　with　SeO2,　V2O5,　MoO3,　K　2CO3　and　en,　and　characterized　by　X-ray　crystal-structure　analysis,　IR,　UV-Vis　DRIS　and　fluorescence　spectra.　It　belongs　to　orthorhombic,　space　group　P212121　with　a　=　12.1386(7),　b　=　17.7118(8),　c　=　11.7092(5)　Å,　V　=　2517.4(2)　Å3,　Z　=　4,　Dc　=　2.987　g/cm3,　Mr　=　1133.89,　μ=　5.419　mm-1,　F(000)　=　2144,　R　=　0.0285,　wR　=　0.0400　and　S　=　0.904.　The　title　compound　contains　two　biprotonized　en　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.　H2en　lies　in　the　tetrahedron　made　up　of　four　[Se2MO5O21]4-.　The　H2en　molecules　are　connected　with　the　anion　and　water　by　hydrogen　bonds　to　form　a　three-dimensional　structure.　At　last,　we　also　discussed　the　electron　structure　of　the　cluster　anion　with　the　B3LYP　method.
