Description
A novel lithium molybdenyl iodate, LiMoO3(IO3), has been prepared by hydrothermal reactions at 170oC. Its crystal structure has been determined from single-crystal X-ray data: space group P21, a=5.4104(4)A, b=5.3158(3)A, c=9.0025(7)A, β=106.863(6)o, Z=2. LiMoO3(IO3) is a new layered material containing [MoO3(IO3)]1- anionic layers separated by Li+ cations. The anionic layer has an unprecedented configuration consisting of WO3-type sheets ''capped'' by IO3- groups. The iodate groups have their stereochemically active nonbonded electron pairs align along the b-axis, which creates the polarity in the structure. Second-harmonic-generation measurements on LiMoO3(IO3) display a response of about 4xKH2PO4. DTA measurements demonstrate that LiMoO3(IO3) is stable up to at least 430oC. UV-vis diffuse reflectance spectrum of this compound shows a high degree of transparency from 1.1 to 2.8eV and a band gap of about 2.8eV
