Novel supramolecules of Ag(I) complexes of the type [Ag(2-ddph)][X] (2-ddph = 2,6-dimethyl-3,5-dicyano-4-(6-methyl-2-pyridyl)-1,4-dihydropyridine; X = BF4−, 1, ClO4−, 2, NO3−, 3 and PF6−, 4) have been prepared by self-assembly of AgX with 2,6-dimethyl-3,5-dicyano-4-(6-methyl-2-pyridyl)-1,4-dihydropyridine (2-ddph) in MeOH–H2O. The elemental analyses and IR have been recorded and all the complexes have been structurally characterized by X-ray crystallography confirming that complexes 1–4 are two-dimensional coordination polymers. The anions BF4− and PF6− in complexes 1 and 4 are not coordinated to the Ag(I) atoms while the ClO4− and NO3− anions in 2 and 3 are coordinated to the metal centers through a monodentate oxygen atom. Complexes 1–3 show 2-D brick-wall structures, while complex 4 shows square grids.
