The title compound, {[Ag(C(19)H(16)N(8))](CF(3)SO(3))}(n), is a coordin-ation polymer with cationic chain motif. The Ag(+) cation is coordinated by two unsubstituted imidazolyl N atoms of two independent 2-paBIM ligands [2-paBIM is bis-{2-[(E)-phenyl-diazen-yl]-1H-imidazol-1-yl}methane]. The shortest Ag⋯Ag separation in a cationic chain is 8.841 (2) Å and the dihedral angle between two 2-phenyl-diazenyl-imidazole planes in the same ligand is 74.7 (3)°. Weak C-H⋯O interactions are seen in the crystal.
