Yellow needle-shaped crystals of the title compound, {[Ag(C30H22N4)][Ag(NO3)2]}n, were obtained by the reaction of AgNO3and 9,10-bis(benzimidazol-1-ylmethyl)anthracene (L) in a 2:1 ratio. The asymmetric unit consists of two AgIcations, one halfLligand and one nitrate anion. One AgIcation occupies a crystallographic inversion centre and links two N-atom donors of two distinctLligands to form an infinite one-dimensional coordination polymer. The second AgIcation lies on a crystallographic twofold axis and is coordinated by two O-atom donors of two nitrate anions to form an [Ag(NO3)2]−counter-ion. The polymeric chains are linked into a supramolecular frameworkviaweak Ag...O [3.124 (5) Å] and Ag...π (2.982 Å) interactions (π is the centroid of an outer anthracene benzene ring). The π interactions contain two short Ag...C contacts [2.727 (6) and 2.765 (6) Å], which can be considered to define Ag–η2-anthracene bonding interactions. In comparison with a previously reported binuclear AgIcomplex [Du, Hu, Zhang, Zeng & Bu (2008).CrystEngComm,10, 1866–1874], this new one-dimensional coordination polymer was obtained by changing the metal–ligand ratio during the synthesis.
