Title: Bridgman crystal growth of Yb{sub 2}Ru{sub 3}Ge{sub 4}-A ternary germanide with a three-dimensional network of condensed distorted RuGe{sub 5} and RuGe{sub 6} units

Abstract

The germanide Yb{sub 2}Ru{sub 3}Ge{sub 4} was synthesized from the elements using the Bridgman crystal growth technique. The monoclinic Hf{sub 2}Ru{sub 3}Si{sub 4} type structure was investigated by X-ray powder and single crystal diffraction: C2/c, Z=8, a=1993.0(3) pm, b=550.69(8) pm, c=1388.0(2) pm, {beta}=128.383(9){sup o}, wR {sub 2}=0.0569, 2047 F {sup 2} values, and 84 variables. Yb{sub 2}Ru{sub 3}Ge{sub 4} contains two crystallographically independent ytterbium sites with coordination numbers of 18 and 17 for Yb1 and Yb2, respectively. Each ytterbium atom has three ytterbium neighbors at Yb-Yb distances ranging from 345 to 368 pm. The shortest interatomic distances occur for the Ru-Ge contacts. The three crystallographically independent ruthenium sites have between five and six germanium neighbors in distorted trigonal bipyramidal (Ru1Ge{sub 5}) or octahedral (Ru2Ge{sub 6} and Ru3Ge{sub 6}) coordination at Ru-Ge distances ranging from 245 to 279 pm. The Ru2 atoms form zig-zag chains running parallel to the b-axis at Ru2-Ru2 of 284 pm. The RuGe{sub 5} and RuGe{sub 6} units are condensed via common edges and faces leading to a complex three-dimensional [Ru{sub 3}Ge{sub 4}] network. - Graphical abstract: Condensation of the Ru1Ge{sub 5}, Ru2Ge{sub 6}, and Ru3Ge{sub 6} units in the structure of Yb{sub 2}Ru{sub 3}Ge{sub 4}.
