摘　　要：采用水热合成方法,以氧化镧、硫酸和哌嗪、水为原料得到了具有新颖结构的硫酸镧.单晶衍射结果表明该化合物是有机胺支撑的、通过镧与硫酸根配位形成的层状开放骨架结构,该化合物也用元素分析、差热-热重和红外进行了表征.结果表明结构解析能够同相应的表征较好地吻合.A novel compound La_2(SO_4)_6(C_4N_2H_(12))_3·3H_2O has been synthesized from H_2SO_4, La_2O_3, piperazine, and H_2O in aqueous solution hydrothermally and characterized by TGA, IR spectrum, XRPD, and single-crystal X-ray diffraction analysis. X-ray crystallography reveals that the title compound is a novel two-dimensional framework material constructed from coordination between lanthanum and sulfates. Goodness-of-fit on F^2 is 1.015 and R indices (all data) are R1 = 0.0423, wR2 = 0.0873.
