Na5[CoO2]CO3 was prepared via the azide/nitrate route. Stoichiometric mixtures of the precursors (Co3O4, NaN3, NaNO3 and Na2CO3) were heated in a special regime up to 500 °C and annealed at this temperature for 50 h in silver crucibles. Single crystals have been grown by subsequent annealing of the powder at 500 °C for 2000 h in silver crucibles, which were sealed in glass ampoules under dry Ar. According to the X-ray analysis of the crystal structure (P4/mmm, Z = 1, a = 4.6467(4), c = 8.2577(6) Å ). Na5[CoO2]CO3 is isostructural with Na5[NiO2]CO3 and contains Co1+, which is coordinated by two oxygen atoms forming a dumb-bell. Na5CoCO5 decomposes at 600 °C to Na3CoO2 and Na2CO3.
