Tris(3-amino-5,6-dimethyl-1,2,4-triazine-κN2)silver(I) trifluromethanesulfonate–3-amino-5,6-dimethyl-1,2,4-triazine (1/1)

Abstract

The asymmetric unit of the title compound, [Ag(C5H8N4)3](CF3O3S)·C5H8N4, contains two cations, two anions and two uncoordinated 3-amino-5,6-dimethyl-1,2,4-triazine (admt) ligands. It was prepared from the reaction of silver trifluoromethanesulfonate and admt in a 2:3 molar ratio. Both silver(I) ions are bonded to three admt molecules via their 2-position triazine N atoms in almost regular trigonal–planar geometries. Three intramolecular N—H...N hydrogen bonds between adjacent admt molecules in each cation help to maintain their overall near planarities (r.m.s. deviations for the 28 non-H atoms = 0.139 and 0.153 Å). In the crystal, numerous N—H...N, N—H...O, C—H...O, C—H...N and C—H...F hydrogen-bonding interactions link the components into a three-dimensional network.
