In the title complex, [Ag(C(3)H(3)N(4)O(2))](n), the Ag(I) atom is four-coordinated in a slightly distorted tetra-hedral coordination geometry by two N atoms from two tetra-zole-1-acetate (tza) ligands and two O atoms from the other two tza ligands. The tza ligand bridges two Ag atoms through the carboxyl-ate O atoms and simultaneously binds to the other two Ag atoms through the tetra-zole N atoms, forming a two-dimensional network parallel to (100).
