Crystal structure of the Al₂₀Mn_5.37Ni_1.31 phase in the Al-Mn-Ni system.

ABSTRACT: The inter-metallic phase with composition Al₂₀Mn_5.37Ni_1.31 (icosa-aluminium penta-manganese nickel) was synthesized by high-temperature sinter-ing of a mixture with initial chemical composition Al₆₀Mn₇Ni₃. Al₂₀Mn_5.37Ni_1.31 adopts the Co₂Al₅ structure type in space-group type P6₃/mmc, replacing the Co atoms with the transition-metal atoms Mn and Ni. Structure analysis revealed that one of the two transition-metal sites is partially occupied by Ni [refined occupancy 0.342 (2)] and the other is co-occupied by Mn and Ni with a ratio of 0.895 (14):0.105 (14). The present refined chemical composition is supported by complementary energy-dispersive X-ra
