A novel 3-D inorganic bimetallic compound Ag2Mo2O7 has been hydrothermally synthesized and structurally characterized by X-ray diffraction. The compound crystallizes in mono- clinic, space group P21/c with a = 6.1274(3), b = 13.1836(6), c = 7.8780(3) ?, β = 110.673(3)°, V = 595.42(5) ?3, Z = 4, Mr = 519.62, Dc = 5.797 g/cm3, F(000) = 936, μ(MoKα) = 10.579 mm?1, F(000) = 936, the final R = 0.0204 and wR = 0.0477 for 1268 observed reflections with I > 2σ(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.

In the title compound, the [Mo4O16] n8n? through O? Ag? O bridging bonds to form a 3D network. It represents an economic linking mode between the isopolyoxomolybdate chain and the transition metal oxide cluster. IR, TGA and fluorescence properties of the title compound are also studied.
