Popis:	Two new one-dimensional coordination polymers, [Zn(L)2 (C2N3)2] n and [Cd(L)2(C2N3)2] n (L = 4-Cyanobenzylidene nicotinohydrazide, C2N3 = dicyanamide anions), have been synthesized and structurally characterized. These two compounds are isomorphs. Each metal center is coordinated to six nitrogen atoms from two L molecules and four dicyanamide anions, defining distorted octahedral coordination geometry. Dicyanamide anions acting as linear bridging ligands connect metal centers to form 1D chains along the crystallographic a axis. Furthermore, an interesting (3,4)-connected (83)2(85.10)-tfc topology of supramolecular 3D networks through hydrogen bonds based on 1D chains is constructed. Luminescent property of the Zn(II) coordination polymer has also been studied.
