Abstract
Reactions of silver(I) perchlorate and triflate with the triazine ligands 2,4,6-trimethoxy-1,3,5-triazine (L 1) and 2,4,6-triphenyl-1,3,5-triazine (L 2) have provided three novel silver complexes: [Ag(L 1) 2](ClO 4) ( 1), [Ag(L 1) 2](CF 3SO 3) ( 2) and [Ag 2(L 2)(CF 3SO 3) 2] ( 3). The crystal structures of these complexes have been determined by single-crystal X-ray diffraction. Each complex exhibits distinct coordination behavior and different frameworks. Complex 1 has a 1D stepped framework in which one crystallographically independent metal center interacts with two L 1 molecules and strong π–π interactions between the triazine planes of two L 1 molecules exist. On the other hand, complex 2 has a herringbone-like molecular packing in which the triflate ions are arranged between mononuclear complex cations. In complex 3, L 2 molecules are suspended between two double chains of silver triflate through the coordination to silver(I) ions to form the 2D sheet network structure. The factors that influence the crystal structure and packing are discussed.
