NaGdP2O7 was synthesized by the solid-state reaction of Gd2O3 with Na2CO3 and 4(NH4)2HPO4 at 650°C. The X-ray powder diffraction data of NaGdP2O7 was indexed in the orthorhombic system with the approximate unit cell dimensions of a = 12.44 , b = 15.00, and c = 15.87 Å and the space group is Pmm2. Analysis of the vibrations of the P2O4-7 ion according to C2v symmetry and approximate band assignments
通过在650℃下使Gd 2 O 3与Na 2 CO 3和4(NH 4)2 HPO 4固相反应来合成NaGdP 2 O 7。NaGdP 2 O 7的X射线粉末衍射数据在正交晶系中进行了索引,其近似晶胞尺寸为a = 12.44,b = 15.00和c = 15.87Å,空间群为Pmm2。振动分析P 2 O 4- 7离子的含量根据这项工作中还报告了C 2v对称性和红外光谱的近似谱带分配。POP波段被发现是非线性的,红外光谱和拉曼光谱的一些重合表明最可能的空间群是非中心对称的。
