The inter-metallic phase with composition Al 0.88 Cu 0.94 Fe 0.18 was synthesized by high-temperature sinter-ing of a mixture with initial chemical composition Al 78 Cu 48 Fe 13 . Al 0.88 Cu 0.94 Fe 0.18 adopts the CsCl structure type in space-group Pm m . The structure analysis revealed that one site is co-occupied by Al and Cu with a ratio of 0.88 (5):0.12 (5) and the other is co-occupied by Fe and Cu with a ratio of 0.2 (4):0.8 (4). The Al/Cu⋯Fe/Cu separation is 2.5465 (13) Å.
