Replacing the hydrogen in the intermolecular hydrogen bond of the cyanuric acid–bipyridyl adduct by Ag(I)

A complex between cyanuric acid (CA), 4,4´-bipyridyl (BP) and Ag(I), with the composition, [Ag2(C3H2N3O3-kN)2 (C10H8N2-kN)] has been prepared. Crystal structure analysis shows that it has a chain structure in which the CA molecules are linked to the BP units through silver atoms by the formation of N–Ag– N bonds, wherein one of the hydrogens of CA is replaced by Ag(I), showing thereby the chains connected to one another by N–H...O hydrogen bonds formed between the CA molecules. This intermolecular chain structure resembles the chain structure of the CA.BP adduct where CA-BP-CA chains formed by N–H...N hydrogen bonds are linked to one another by N–H...O hydrogen bonds between the CA molecules.
