Abstract: The title compound, {[Ag(C7H8N4)]PF6}n, has a one-dimensional zigzag chain structure. The Ag+ cation and the PF6- anion reside on crystallographic inversion centres. The Ag+ cation is coordinated by the unsubstituted N atoms of two separate 1,1'-methylenediimidazole ligands. The closest Ag...Ag separation in the same cationic chain is 7.704 (2) Å and the dihedral angle between the two imidazole rings in the same ligand is 85.5 (1)°. A two-dimensional layer framework is formed by weak Ag...N interactions between adjacent chains, with an Ag...N distance of 3.472 (2) Å.
