title: 4-[3-(Isonicotino-yloxy)propoxycarbon-yl]pyridinium diiodidoargentate(I).
abstract: The structure of the title compound, (C(15)H(15)N(2)O(4))[AgI(2)], consists of an organic 4-[3-(isonicotino-yloxy)propoxycarbon-yl]pyridinium cation which has a gauche-gauche (O/C/C/C-O/C/C/C or GG') conformation and lies on a twofold rotation axis, which passes through the central C atom of the aliphatic chain, and an inorganic [AgI(2)](-) anion. In the complex anion, the Ag(+) cation is bound to two I(-) anions in a linear geometry. The anion was modelled assuming disorder around a crystallographic inversion centre near the location of the Ag(+) cation. The crystal packing is stabilized by a strong inter-molecular N-H⋯N hydrogen bond, which links the cations into zigzag chains with graph-set notation C(16) running along the face diagonal of the ac plane. The N-bound H atom is disordered over two equally occupied symmetry-equivalent sites, so that the mol-ecule has a pyridinium ring at one end and a pyridine ring at the other.
