摘要：

Li0.5M0.25TiOAsO4 (M=Mg,Co,Ni,Zn) oxyarsenates powders were prepared by coprecipitation method from dilute solution of Li2CO3, M(NO3)(2) X H2O (M = Mg, Co, Ni, Zn), (NH4)H2AsO4 and TiCl4 in ethanol. The resulting powders, obtained after drying at about 60 degrees C, were heated progressively with intermittent grindings at 200 degrees C-750 degrees C in air. These new compounds crystallize in the monoclinic system with space group P2(1)/ c. Their parameters are functions of M2+, ion size. (C) 2006 International Centre for Diffraction Data.
