Three new silver alkylenediphosphonates,[Ag2(HO3PCH2CH2CH2CH2PO3H)]1,[Ag4(O3PCH2CH2CH2CH2PO3)]2 and [Ag4(O3PCH2CH2CH2PO3)(H2O)]3,have been hydrothermally synthesized and characterized by X-ray single-crystal and powder diffraction, elemental analyses, IR and thermogravimetric analyses (TGA). The structures of these compounds are all three dimensional pillar-like open-frameworks with 18-membered [Ag2O4P4C8] channels for compound 1 and 2, and 16-member [Ag2O4P4C6] channels for compound 3. Both 2 and 3 contain interesting two dimensional Ag(Ⅰ) networks based on Ag…Ag interactions. 1,4-Butylene- and 1,3-propylene diphosphonate groups of 2 and 3 bond the first and second maximum metal atoms among metal organodiphosphonates with linking sixteen and fifteen silver(Ⅰ) atoms, respectively. In addition, the coordinated water molecules of 3 can be reversibly removed and recovered.
