Li₁₂Cu_12.60Al_14.37: a new ternary derivative of the binary Laves phases

V. Pavlyuk, G. Dmytriv, I. Tarasiuk, I. Chumak and H. Ehrenberg

Synopsis: Li₁₂Cu_12.60Al_14.37 crystallizes as a new structure type and belongs to the Laves phases structural family. The pseudo-Frank-Kasper polyhedra are typical for the Li and Al atoms. The polyhedra around the statistical mixtures of (Cu,Al)1 and (Al,Cu)2 are distorted icosahedra. The electronic structure calculations by the TB-LMTO-ASA method show strong Al-Al interactions.

Formula: Li₁₂Cu_12.60Al_14.37
