摘要：

The preparation and crystal structure of the novel ternary oxides M3AuO (M = Cs, Rb, K) containing anionic gold is reported. Cs3AuO (a = 7.830(1) angstrom, c = 7.060(1) angstrom) crystallizes as a hexagonal, Rb3AuO (a = 5.501(1) angstrom) and K3AuO (a = 5.240(1) angstrom) as a cubic anti perovskite. Concerning to the ionic description (M+)3Au-O2- in Cs3AuO gold exists as an anion. In Rb3AuO and K3AuO the anionic character of gold decreases respectively. The analysis of bond length and molar volumes gives support to this view, as well as investigations of conductivity and magnetic properties do.
