Abstract
New ternary stannide YbPdSn2 was synthesized from the elements in a sealed tantalum tube in a high-frequency furnace. YbPdSn2 was characterized throug h X-ray powder and single crystal data: Cmcm. a=442.4(2), b = 1108.6(3), c = 738.4(2) pm. wR2 = 0.0450, 317 F-2 values, and 16 variable parameters. Yb PdSn2 crystallizes with the MgCuAl2 type structure, a ternary ordered varia nt of the Re3B type. The tin sublattice of YbPdSn2 corresponds to a distort ed lonsdaleite-like arrangement with Sn-Sn distances varying from 303 to 33 6 pm.
