摘要
采用薄层法制备了磷酸钇二水合物YPO4·2H2O，并在室温下通过x射线粉末衍射得到了其晶体结构。用直接法求解了YPO4·2H2O的结构，并用Rietveld分析法对其进行了细化。该化合物在单斜空间群C2/c中结晶，晶胞尺寸a = 6.15326(3)， b = 14.99687(8)， c = 5.57848(3) a， β = 115.4319(4)o, V = 464.896(4) a3, Z = 4。它具有石膏型晶体结构，具有金属-磷酸盐二维聚合物网络，平行于ac平面。由钇原子协调的水分子在层之间提供氢键，形成一个三维网络。将YPO4·2H2O的晶体结构与先前研究的同型Y1-x(Gd,Dy,Er)xPO4·2H2O (x = 0.053)的晶体结构进行比较。
PREPARATION AND STRUCTURE OF THE YTTRIUM PHOSPHATE DIHYDRATE YPO4·2H2O
The yttrium phosphate dihydrate YPO4·2H2O was synthesized by thin-layer technique, and its crystal structure was obtained from X-ray powder diffraction data at room temperature. The structure of YPO4·2H2O was solved by direct methods and refined using the Rietveld analysis. The compound crystallizes in the monoclinic space group C2/c, with unit cell dimensions a = 6.15326(3), b = 14.99687(8), c = 5.57848(3) A, β = 115.4319(4)o, V = 464.896(4) A 3 , Z = 4. It has the gypsum-type crystal structure, with metal-phosphate 2D polymeric network, parallel to the ac plane. Water molecules, coordinated by the yttrium atoms, provide hydrogen bonding between the layers, resulting into a three-dimensional network. The crystal structure of YPO4·2H2O is compared with that of isotypic Y1-x(Gd,Dy,Er)xPO4·2H2O (x = 0.053), investigated earlier.
