catena-Poly[[silver(I)--1,4-di-4-pyridyl-2,3-diazabuta-1,3-diene] methanesulfonate]

Abstract: The asymmetric unit in the polymeric title compound, {[Ag(C₁₂H₁₀N₄)]CH₃SO₃}_n, comprises two Ag atoms, a 4-pyridinealdazine molecule in a general position, two 4-pyridinealdazine molecules each disposed about a centre of inversion, and two methanesulfonate anions. The Ag atoms are in linear geometries within N₂ donor sets. The topology of the polymer is linear and the strands are connected into double chains via weak argentophilic AgAg [3.2088 (10) Å] interactions that stack along the b axis interspersed by the methanesulfonate anions. These layers are consolidated in the crystal structure primarily via weak AgO contacts (AgO > 2.69 Å).
