Title: Crystal growth and structure of R{sub 2}Ir{sub 2}O{sub 7} (R=Pr, Eu) using molten KF

Abstract

Single crystals of R{sub 2}Ir{sub 2}O{sub 7} (R=Pr, Eu) have been synthesized using molten KF at 1373K. The pyrochlore compounds crystallize in a cubic space group Fd3-barm (No. 227, origin choice 2), with Z=8. At room temperature, the lattice parameters are a=10.3940(4)A, V=1122.92(7)A{sup 3} and a=10.274(3)A, V=1084.5(6)A{sup 3} for Pr{sub 2}Ir{sub 2}O{sub 7} and Eu{sub 2}Ir{sub 2}O{sub 7}, respectively. In this paper, we report the crystal growth of R{sub 2}Ir{sub 2}O{sub 7} (R=Pr, Eu) and their structure determinations from single crystal X-ray diffraction experiments at temperatures of 110, 115, and 298K.
