Air and moisture sensitive K 5 [CuO 2 ][CO 3 ] was prepared via the azide/nitrate route from stoichiometric mixtures of the precursors CuO, KN 3 , KNO 3 and K 2 CO 3 . According to the single‐crystal X‐ray analysis of the crystal structure [ P 4/ nbm , Z = 2, a = 7.4067(5), c = 8.8764(8) Å, R 1 = 0.053, 433 independent reflections] K 5 [CuO 2 ][CO 3 ] represents an ordered superstructure of Na 5 [NiO 2 ][CO 3 ]. The structure contains isolated [CuO 2 ] 3– dumbbells and CO 3 2– anions, with the latter not connected to the transition element. Raman spectroscopic measurements confirm the presence of CO 3 2– in the structure.
