A Variety of Different Occupancies in Isotypic Compounds: Ternary Antimonides and Bismuthides with the Ideal Formulas T5T′Sb3 and T5T′Bi3 (T = Ti, Zr, Hf; T′ = Late Transition Metals) and the Binary Antimonide Ti4.80Sb3.29, all Crystallizing with “Filled” Mn5Si3 (Hf5CuSn3) Type Structure and Structure Refinement of Ti5Sb2.85 with β-Yb5Sb3 Type Structure

✦ Synopsis
Fourteen new binary and ternary compounds are reported. The ternary antimonides Ti 5 T 'Sb 3 (T ' = Co, Ni, Zn, Ru, Rh, Pd, Pt), T 5 T 'Sb 3 (T = Zr, Hf; T ' = Pd, Pt) and the bismuthides Ti 5 CuBi 3 and Ti 5 ZnBi 3 were synthesized by reaction of the elemental components at high temperatures. They crystallize with the hexagonal Hf 5 CuSn 3 (ªfilledº Mn 5 Si 3 , Mo 5 Si 3 C) type structure. Structure refinements from single-crystal X-ray diffractometer data (Ti 5±x ZnSb 3 , Ti 5±x Pt 1±y Sb 3 , and Ti 5±x Zn 1±y Bi 3+z ) and powder diffractometer data (Ti 5±x Cu 1±y Sb 3 ) reveal in some cases considerable deviations from the ideal composition with x, y, and z values up to 0.66. This is also the case for the ªself-filledº binary phase Ti 4.80 Sb 3.29 as is shown by a structure refinement from X-ray powder diffractometer data. The crystal structure of Ti 5 Sb 2.85 with b-Yb 5 Sb 3 type structure was confirmed by a refinement from single-crystal data.
