catena-Poly[bis[silver(I)-μ(2)-4,4'-bipyridine-κ(2)N:N']naphthalene-2,6-dicarboxylate tetrahydrate]: self-assembly of a supramolecular framework via coordination bonds and supramolecular interactions

Abstract

The ultrasonic reaction of AgNO3, 4,4'-bipyridine (bipy) and naphthalene-2,6-dicarboxylic acid (H2NDC) gives rise to the title compound, {[Ag-2(C10H8N2)(2)](C12H6O4)center dot 4H(2)O}(n). The NDC dianion is located on an inversion centre. The Ag-I centre is coordinated in a linear manner by two N atoms from two bipy ligands. The crystal structure consists of one-dimensional Ag-I-bipy cationic chains and two-dimensional NDC-H2O anionic sheets, constructed by coordination bonds and supramolecular interactions, respectively.
