Abstract: The asymmetric unit of the title compound, (C14H20N4)[Ag(CN)2]2, contains one-half of a centrosymmetric 2,2'-(p-phenylene)bis(1,4,5,6-tetrahydropyrimidinium) (H2btb) cation and one [Ag(CN)2]- anion. In the anions, the AgI atoms adopt near linear coordination modes with the two attached cyanide groups [C-Ag-C = 173.3 (2)°]. In the crystal structure, each H2btb cation links four [Ag(CN)2]- anions via N-HN hydrogen bonds into a one-dimensional ribbon.
