Single crystals of KBiO2 (colourless) and RbBiO2 (colourless) were obt
ained by solid state reaction of the respective binary metal oxides. B
oth crystal structures (KBiO2: C2/c; a = 783.13(9), b = 790.92(1), c =

]-chains extending along the [001] direction. The compounds are isostr
uctural with NaBiO2 and CsBiO2.
