摘要

Rb3CoO2 was prepared via the azideitrate route. Stoichiometric mixtures of the precursors (Co3O4, RbN3 and RbNO3) were heated in a special regime up to 500 degreesC and annealed at this temperature for 100 h in silver crucibles. The crystal structure of the obtained red product was solved and refined by powder methods (Pnma, Z = 4, 12.3489(2), 7.6648(1), 6.2251(1) Angstrom). Rb3CoO2 is isostructural with K3CoO2 and contains Co1+, which is coordinated by two oxygen atoms forming a slightly distorted dumb-bell. Rb3CoO2 decomposes at 580 degreesC to Rb2O Co and CoO.
