Synthesis and crystal structure of a 1D coordination polymer {[p-FBzlPh3P]+[ZnCl2(NA)]-}n (NA=nicotinic acid)

A metal-organic coordination polymer, ([p-FBzlPh(3)P] [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 P2(1)/n, a=0.983 6(3) nm, b=2.567 0(7) nm, c=1.133 4(3) nm, beta=94.46 degrees, V=2.853 0(14) nm(3), Z=4, R-1=0.049 3, wR(2)=0.126 5 and S = 1.037. The structure of compound 1 features as novel one-dimensional structure, and interestingly, the [p-FBzlPh(3)P](+) 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.
