一维链状配位聚合物{[p-FBzlPh3P]+[ZnCl2(NA)]-}n的合成与晶体结构

A metal-organic coordination polymer, {[p-FBzlPh₃P] [ZnCl₂(NA)]}_n(1) (NA=nicotinic acid), has been hydrothermally synthesized and characterized by IR, UV-Vis, TG analysis, elemental analysis, fluorescence analysis and single crystal structure determination. Compound 1 crystallizes in the monoclinic system, space group P2₁/n, a=0.983 6(3) nm, b=2.567 0(7) nm, c=1.133 4(3) nm, β=94.46°, V=2.853 0(14) nm³, Z=4, R₁=0.049 3, wR₂=0.126 5 and S=1.037. The structure of compound 1 features as novel one-dimensional structure, and interestingly, the [p-FBzlPh₃P]⁺ counter-cations alternately reside both sides of the one-dimensional anionic chains of the zigza-chain polymer, and the supermolecule is formed by intermolecular weak hydrogen bond. Compound 1 exhibits strong fluorescence in solid state at room temperature. CCDC: 664276.
