The title complex, bis[3,3'-(pyridine-4-imino-kappaN(1))dipropanenitrile]silver(I) perchlorate, [Ag(CEAP)(2)]ClO(4) (CEAP is 4-[N,N-bis(2-cyanoethyl)amino]pyridine, C(11)H(12)N(4)), has been prepared and characterized. The unit cell consists of two crystallographically non-equivalent molecules. Cation cavities are constructed by [Ag(CEAP)(2)](+) cations through hydrogen bonds, and the ClO(4)(-) anions

The title compound, 3,3'-(4-pyridylimino)dipropanenitrile, C(11)H(12)N(4), has a twofold axis and consists of a pyridine ring head and two cyanoethyl tails, the three groups being linked by an N atom. The planar geometry around the amino N atom suggests conjugation with the pi-system of the pyridine ring. The molecules are stacked in a layer structure via relatively weak to very weak intermolecular

A dinuclear copper(II) complex (1) of a Schiff-base ligand L [2-((Z)-(3-((3-((Z)-2-hydroxybenzylideneamino)propyl)(pyridin-4-yl)amino)propylimino)methyl)phenol] was synthesized and characterized. Complex 1 has a [2+2] ring structure formed by two ligands and two central atoms, and each central metal atom lies in a distorted tetrahedral environment.
