N2 - The structure of a rhombohedral λ-AlFeSi phase was determined by means of the single crystal X-ray structural analysis: space group R3̄ (no. 148), a = 10.222(2) Å, c = 19.668(2) Å, V = 1779.8(5) Å 3, atoms/cell = 123, F(0 0 0) = 1950, Dcalc = 3.802 Mg m-3, R(F) = 0.0226 for observed 1517 reflections measured by Mo Kα radiation (λ = 0.71073Å). Coordination polyhedra of three Fe sites show features similar to those in α- and β-AlFeSi structures. The ordering model for Si is also suggested.
