The structure was characterized by elemental analysis, IR spectroscopy and X ray single crystal diffraction. X ray single crystal analysis reveals the structure consists of [La(C8H6NO2)3]n. It crystallizes in monoclinic crystal system with space group P2(1)/c. Crystallographic date: a=0. 7889(3)nm, b=2.5916(9)nm, c=1.1489(4)nm, α =90.00° , β =95.219(6)° , γ =90.00° , V=2.3393(15)nm3, Z=4, Dc=1.656g· cm- 3, μ =1.871mm- 1, F(000)=1152, R1=0.0328, wR2=0.0522.
