Overlooked Binary Compounds Uncovered in the Reinspection of the La-Au System: Synthesis, Crystal Structures, and Electronic Properties of La₇Au₃, La₃Au₂, and La₃Au₄.

ABSTRACT: Although compound formation between two elements is well studied, thorough investigations make it possible to uncover new binary compounds. A re-examination of the La-Au system revealed three new phases, which were characterized with respect to their structural and electronic properties as well as thermal stability: La₇Au₃ (Th₇Fe₃ type, space group P6₃mc, Pearson code hP20) appears to be metastable. It can be obtained by slow crystallization from a stoichiometric melt. La₃Au₂ (U₃Si₂ type, space group P4/mbm, Pearson code tP10) is stable up to 1013 K, where it decomposes peritectically. La₃Au₄ (Pu₃Pd₄ type, s
