【 摘 要 】

The new intermetallic compound Ru₁₁Lu₂₀ was obtained as black single crystals during an attempted comproportionation reaction of lutetium(III) chloride, LuCl₃, with metallic lutetium in the presence of ruthenium metal at 950 °C. Ru₁₁Lu₂₀ crystallizes with the trigonal space group R-3, Z = 6, a = 1255.1(1), c = 2973.0(4) pm, R₁ for all data: 0.0380. Ruthenium atoms center eight-, nine- and ten-vertex polyhedra of lutetium atoms which are connected in a complicated manner to a three-dimensional network.
