The crystal structure of the title compound, [Ag₂(C₈H₇O₂)₂]_n, features polymeric chains extending along the a axis, with the two Ag⁺ cations in a distorted trigonal coordination. The range of Ag-O bond lengths is 2.169 (2)-2.433 (2) Å, whereas the AgAg separations are in the range 2.8674 (4)-3.6256 (5) Å. The 2-methylbenzoate groups are oriented at a dihedral angle of 60.7 (1)° with respect to each other.
