چکیده
The asymmetric unit of the title compound, (C(14)H(20)N(4))[Ag(CN)(2)](2), contains one-half of a centrosymmetric 2,2'-(p-phenyl-ene)bis-(1,4,5,6-tetra-hydro-pyrimidinium) (H(2)btb) 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 H(2)btb cation links four [Ag(CN)(2)](-) anions via N-H⋯N hydrogen bonds into a one-dimensional ribbon.
