Yb7Al5Ge8, an intergrowth of TiNiSi, AlB2 and CsCl type columns
Description
Al5Ge8Yb7, Mr=1926.907, monoclinic, mS40, C2/m-i9da, a=15.958(3), b=4.2871(6), c=12.611(2) A, β=95.78(2)deg, V=858.4(2) A3, Z=2, Dx=7.455 Mg m-3, λ(Mo Kα)=0.71073 A, μ=51.444 mm-1, F(000)=1622, T=300 K, wR=0.044 for 1002 contributing unique reflections. This new structure type can be considered as an intergrowth of TiNiSi, AlB2 and CsCl type columns. The Ge coordination of the Al atom is mostly tetrahedral. The best chance of finding ternary rare-earth structures where Al and Ge atoms have different coordinations seems to occur with ternary compounds formed with small rare-earth elements. (orig.)
