Abstract

The compound YbAl3(BO3)4 belongs to huntite, space group R32 with cell parameters: a = 9.251(2), c = 7.189(3) ? Z = 3, Dc = 4.574 g/cm3, F(000) = 675.0, V = 532.84 3, ?= 13.63 mm-1, (MoK? = 0.71073 ? Mr = 489.22, (YbAl3B4O12), the final R = 0.0286 and wR = 0.0710. The Yb3+ ion occupies the trigonal prismatic site and the Al3+ ion occupies the octahedral site. There are two sets of (BO3)3- planar triangles. The Yb3+ ions are connected by means of YbOAl[B(2)]Yb with the distance 5.854 ?
