title: A polyoxometalate-based inorganic-organic hybrid polymer constructed from silver-Schiff base building block and Keggin-type cluster: Synthesis, crystal structure and photocatalytic performance for the degradation of rhodamine B.
abstract: One polyoxometalate-based inorganic-organic hybrid polymer [Ag3L4(PMo12O40)(CH3OH)]·CH3OH (1), where L is N,N'-bis(furan-2-ylmethylene)hydrazine, has been synthesized at room temperature and structurally characterized by infrared spectroscopy, ultraviolet-visible spectroscopy, elemental analysis, X-ray powder diffraction and X-ray single-crystal crystallography. The structure of 1 exhibits a crystalline one-dimensional polymer constructed by the connections of Keggin-type [PMo12O40](3-) anions and [Ag3L4](3+) units, in which each Ag(I) center adopted a distorted square pyramidal environment. The spectroscopic experiments show that polymer 1 not only is potential semiconductor materials but also displays the obvious photocatalytic performance for the degradation of rhodamine B.
