Catena-Poly[[silver(I)-μ-1,1′-methylenediimidazole] hexafluoridophosphate

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) A 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) A.
