摘要

Gold disproportinates in the presence of the Zintl phases Ba3P2 or Ba3As2 forming BaAuP and BaAuAs, respectively, and BaAu2. The air and moisture sensitive ternary compounds crystallise in the ZrBeSi type of structure, an ordered variant of AlB2: BaAuP (P6(3)/mmc; a = 440.68(6) pm; c = 899.8(2) pm; R-1 = 0.0237; 183 independent reflections); BaAuAs (P6(3)/mmc; a = 453.53(5) pm; c = 902.7(1) pm; R-1 = 0.0255; 168 independent reflections). Both compounds, which are accessible as pure phases by reacting BaP or BaAs with gold, can be classified as poor metallic conductors.
