Abstract
Abstract
YbIrMg was obtained from a reaction of the elements in an equiatomic ratio in a sealed tantalum ampoule in a muffle furnace. The TiNiSi-type structure of YbIrMg was refined from single crystal X-ray diffractometer data: Pnma, a = 695.72(3), b = 405.84(6), c = 840.57(7) pm, wR = 0.0431, 511 F
2 values and 21 variables. A small degree of Mg/Ir mixing within the three-dimensional [IrMg] network leads to the refined composition YbIr1.024(4)Mg0.976(4). The course of the cell volume in the REIrMg series (Iandelli plot) points to trivalent ytterbium in YbIrMg.
