An organic–inorganic hybrid uranyl nicotinate molybdate polymer and its fluorescent property

A uranyl nicotinate molybdate polymer [UO2(nicot)(MoO3OH)]n (Hnicot = nicotinic acid, NC5H4CO2H) was synthesized by the hydrothermal reaction of uranyl nitrate [UO2(NO3)2 · 6H2O], phosphomolybolic acid (H3PMo12O40) and nicotinic acid. Its crystal structure and fluorescent property were measured. The results show that the crystal packs in the 1D chains of uranyl molybdates with strong fluorescence at the range of 470–520 nm.
