Well-crystallized samples of the rhenium aluminides Re 4 Al 11  and ReAl 6  were obtained by reaction of rhenium with an excess of aluminum. Re 4 Al 11  was found to be isotypic with Mn 4 Al 11 . The MnAl 6  type structure of ReAl 6  was confirmed. The crystal structures of both compounds were refined from single-crystal X-ray data. Re 4 Al 11 :P1̄, Z = 1, a = 516.0(1) pm, b = 896.3(2) pm, c = 516.9(1) pm, a = 90.44(1)°, β = 99.76(1)°, γ = 105.17(1)°, V = 0.2271 nm 3 , R = 0.036 for 2315 structure factors and 74 variable parameters. ReAl 6 : Cmcm, Z = 4, a = 761.0(1) pm, b = 660.5(1) pm, c = 903.4(1) pm, V = 0.4541 nm 3 , R = 0.013 for 711F values and 23 variables. In both structures the rhenium atoms have ten aluminum neighbors at distances from 245 to 277 pm. The Al-Al distances cover the whole range from 251 to 362 pm rather continuously. The previously reported compound Re 2 Al with the tetragonal MoSi 2 -type structure has the lattice constants a = 298.1(1) pm, c = 958.4(4) pm, V = 0.08519 nm 3 . ReAl 6  shows Pauli-paramagnetism.
