A　novel　3-D　inorganic　bimetallic　compound　Ag2MO2O7　has　been　hydrothermally　synthesized　and　structurally　characterized　by　X-ray　diffraction.　The　compound　crystallizes　in　monoclinic,　space　group　P2(1)/c　with　a　=　6.1274(3),　b　=　13.1836(6),　c　=　7.8780(3)　angstrom　beta,　=　110.673(3)degrees,　V　=　595.42(5)　angstrom(3),　Z　=　4,　M-r=　519.62,　D-c.　=　5.797　g/cm(3),　F(000)　=　936,　mu(MoK　alpha)　=　10.579　mm(-1),　F(000)　=　936,　the　final　R　=　0.0204　and　wR　=　0.0477　for　1268　observed　reflections　with　i　＞　2　alpha(I).　In　the　title　compound,　the　[MO4O16](n)(8n-)　chains　are　linked　through　O-Ag-O　bridging　bonds　to　form　a　3D　network.　It　represents　an　unprecedented　linking　mode　between　the　isopolyoxomolybdate　chain　and　the　transition　metal　oxide　cluster.　IR,　TGA　and　fluorescence　properties　of　the　title　compound　are　also　studied.
