  One-Dimensional Zinc and Cadmium Coordination Polymers Constructed by Dicyanamide Anions: Synthesis, Crystal Structure, and Fluorescent Property

  摘要：

  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 (8(3))(2)(8(5).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.
