Catena-Poly[bis[silver(I)-μ2-4,4′-bipyridine-κ2N:N′] naphthalene-2,6-dicarboxylate tetrahydrate]: self-assembly of a supramolecular frameworkviacoordination bonds and supramolecular interactions

Abstract

The ultrasonic reaction of AgNO(3), 4,4'-bipyridine (bipy) and naphthalene-2,6-dicarboxylic acid (H(2)NDC) gives rise to the title compound, {[Ag(2)(C(10)H(8)N(2))(2)](C(12)H(6)O(4)).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-H(2)O anionic sheets, constructed by coordination bonds and supramolecular interactions, respectively.
