2008 Structure D 2000 Er17Ru6Te3: A Highly Condensed Metal-Rich Ternary Telluride. — The title com- pound is synthesized from a mixture of ErTe (prepared from the elements with >95% yield at 750 °C for 3 d), Er, and Ru in a 7:2:2 ratio (Ar, 1250 °C, 14 d, >60% yield), or from a stoichiometric mixture of Er, Ru, and Te (>90% yield). According to single crys- tal XRD, the compound crystallizes in the monoclinic space group C2/m with Z = 4. The structure consists of a complex intermetallic network of intergrown sheets of edge-sharing tricapped trigonal prisms (TCTP), and pairs of rectangular-face-sharing bicapped trigonal prisms (BCTP) built of Er and centered by Ru. This array also con- tains isolated columns of Er-TCTP normal to these sheets, containing Te. Basal face sharing of all Er polyhedra results in a three-dimensional network. — (MEHTA, A.; CORBETT*, J. D.; J. Solid State Chem. 181 (2008) 4, 871-877; Dep. Chem., Iowa State Univ., Ames, IA 50011, USA; Eng.) — W. Pewestorf 33- 006
