在1373 K下，用熔融KF法合成了R2Ir2O7（R = Pr，Eu）单晶。烧绿石化合物以立方空间群Fd（3）在巴m（No.227，原点选择2）上结晶，其中Z = 8。室温下，Pr_2Ir_2O_7和Eu_2Ir_2O_7的晶格常数分别为a = 10.3940（4）埃，V = 1122.92（7）埃和a = 10.274（3）埃，V = 1084.5（6）埃。本文报道了R_2Ir_2O_7（R. = Pr，Eu），并在110、115和298 K下用单晶X射线衍射实验测定了它们的结构。(c)2006爱思唯尔有限公司版权所有。
Single crystals of R2Ir2O7 (R = Pr, Eu) have been synthesized using molten KF at 1373 K. The pyrochlore compounds crystallize in a cubic space group Fd(3) over bar m (No. 227, origin choice 2), with Z = 8. At room temperature, the lattice parameters are a = 10.3940(4) angstrom, V = 1122.92(7) angstrom(3) and a = 10.274(3) angstrom, V = 1084.5(6) angstrom(3) for Pr2Ir2O7 and Eu2Ir2O7, respectively. In this paper, we report the crystal growth of R2Ir2O7 (R. = Pr, Eu) and their structure determinations from single crystal X-ray diffraction experiments at temperatures of 110, 115, and 298 K.
