Replacing the hydrogen in the intermolecular hydrogen bond of the cyanuricacid-bipyridyl adduct by Ag(I)

A complex between cyanuric acid (CA), 4,4'-bipyridyl (BP) and Ag(I), with t he composition, [Ag-2(C3H2N3O3-kappa N)(2) (C10H8N2-kappa N)] has been prep ared. Crystal structure analysis shows that it has a chain structure in whi ch 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 b y Ag(I), showing thereby the chains connected to one another by N-H ... O h ydrogen bonds formed between the CA molecules. This intermolecular chain st ructure resembles the chain structure of the CA.BP adduct when CA-BP-CA cha ins formed by N-H ... N hydrogen bonds are linked to one another by N-H ... O hydrogen bonds between the CA molecules.
