摘要: Abstract Green gleaming brittle single crystals of KAu 5 and RbAu were obtained by the reaction alkalimetal azides with gold powder at 700 °C. The structures determined from single-crystal diffractometer data: space group P 6/ mmm , Z = 1; a 5.663(1) A c 4.483(1) R/R w (w 1) 0.036/0.041, N ( F o 2 ) ⩾ 3 σ (F 234 N(var.) 9; 5.762(2) 4.442(2) 0.048/0.073, 248 9. Both compounds crystallize in CaCu -structure type negligible deviation ideal 1:5 composition.
