The title complex, [Ag(C(7)H(5)O(2))(C(4)H(5)N(3))](n), is a polymer based on a mononuclear silver(I)-centered fragment. The Ag(I) atom is trigonally coordinated by two N atoms from two 2-aminopyrimidine ligands and one O atom from one benzoate anion, giving zigzag polymeric chains with an [-Ag-N-C-N-](n) backbone running along the a axis. It is proposed that intermolecular hydrogen bonding drives the formation of the chain polymer.
