Abstract
Single crystals of BiRe 2 O 6 of typical volume 0.03 mm 3 were grown by chemical vapor transport and characterized using room-temperature single-crystal neutron diffraction in monoclinic C 2/ c symmetry with cell parameters a = 16.1178(11), b = 4.9235(3), c = 5.5278(3) Ã… and β = 92.475(5) ° ( R all = 11.39 wR all = 7.97). The structure contains ordered layers of corner sharing units of Re 2 O 10 with Re-Re distances of 2.519(1) Ã…. The unit cell is doubled along c in comparison to previous studies based on X-ray diffraction data where the layer stacking was described as disorderd. © 2010, Insitute of Physics.
