Abstract
A novel sandwich-type lanthanide polyoxometalate [(CH3)4NH]4Na3[Pr(PW11O39)2] · 12H2O (1) has been synthesized by conventional method and characterized by cyclic voltammetry, IR spectroscopy and single crystal X-ray diffraction. X-ray diffraction result reveals that the sandwich type polyanions are linked by sodium cations to form a structure of zigzag chains, and the chains are further connected into an extensive two-dimensional (2D) framework depending on hydrogen bond. The emission spectrum result shows weak photoluminescence of compound 1. The magnetic studies of compound 1 demonstrate an antiferromagnetic interaction in 1.
