[Ag3(μ-Hbtc)(μ-H2btc)]n (H3btc = 1,3,5-benzenetricarboxylic acid) (1), a new rarely reported Ag(I) three-dimensional coordination polymer with several Ag-Ag bonds, has been synthesized, characterized by elemental analysis and IR spectroscopy and its structure determined by single-crystal X-ray diffraction. The thermal stability of compound 1 was studied by thermal gravimetric and differential thermal analyses. The single crystal X-ray analysis of compound 1 shows that the complex consists of [Ag3(μ-Hbtc)(μ-H2btc)] subunits containing four different Ag environments. The results of studies of the stoichiometry and complex formation in methanol solution supported their solid state stoichiometry.
