摘要
A new gadolinium iodate has been synthesized via hydrothermal method,and its structure was determined as[Gd(H2O)(IO3)2(IO3H2O)]n(1)by X-ray single-crystal diffraction.The 2-D layer is built from the linkage of Gd2O16I4 dimer viaμ2/μ3-bridged iodates,and the quasi-3-D network is generated via weak I···O bonds and hydrogen bonds.FTIR,powder X-ray diffraction(PXRD)and UV-Vis spectra were conducted to characterize the as-synthesized sample.Interestingly,1 exhibits green emission,which might be assigned to electronic transfer within iodate groups.The UV adsorption of 1 hints its UV light-driven photocatalytic property,and as expected,it exhibits photocatalytic activity for the degradation of rhodamine B.Theoretical calculation was conducted to give structure/property correlation.
