Silver(I) carboxylates Ag(RCOO) (R = i-Pr, n-Pr, t-Bu, i-Bu) are synthesized by reactions between AgNO3 and potassium carboxylates in aqueous solutions and characterized by elemental analysis and IR spectroscopy. The X-ray structure of Ag(t-BuCOO) is determined: space group P1 a = 5.810(3) ?, b = 13.646(5) ?, c = 16.700(5) ?, α = 107.56(3)°, β= 90.47(4)°, γ= 94.24(3)°, and Z= 4. The structure consists of polymeric chains formed by silver pivalate dimers, each linked with the two neighbors by two extra Ag-O bonds. The intradimer Ag-O bond lengths are 2.17 and 2.20 ?. In a nitrogen atmosphere at p= 1 atm, all of the Ag(RCOO) compounds decompose to Ag between 120 and 250°C. At a reduced pressure of 0.01 mmHg, they can be sublimed at 220 to 250°C. The thermal stability and volatility of Ag(RCOO) increases in the R order i-Pr n-Pr ～ t-Bu ～ i-Bu.
