Abstract
Two multidentate ligands containing a delocalized π-electron system, 2-{5,5-dimethyl-3-[2-(pyridin-3-yl)-ethenyl]cyclohex-2-enylidene}propanedinitrile (L1) and 2-{5,5-dimethyl-3-[2-(pyridin-2-yl)-ethenyl]cyclohex-2-enylidene}propanedinitrile (L2), were synthesized. By self-assembly of the ligands with silver(I) salts, six supramolecular complexes, [Ag(L1)(TsO)(H2O)]2(1), {[Ag3(L1)2(H2O)](ClO4)3}n (2), {[Ag(L1)(NO3)]·0.5C6H6}n (3), {[Ag(L2)(NO3)]·0.5C6H6}n (4), [Ag(L2)2](ClO4) (5), and [Ag(L2)2](PF6) (6), with different structures and topologies were obtained. In polymer 2, L1 acts as a tridentate ligand to bind Ag(I) ions to form a one-dimensional (1D) supramolecular structure. However, when the ligands adopt bidentate coordination modes to coordinate with Ag(I) ions through the pyridyl nitrogen atom and one cyano nitrogen atom, the dinuclear supramolecular complex 1, 1D coordination polymer 3, and two-dimensional (2D) coordination polymer 4 were obtained. In 5 or 6, only the pyridyl nitrogen atom of L2 l...
