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 Ag^I 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.
