Na 5 [CuO 2 ](OH) 2 has been obtained as orange single crystals from mixtures of NaOH, Na 2 O and Cu 2 O in sealed Ag containers. The crystal structure has been refined from X‐ray diffraction data (IPDS data, Pnma, Z = 4, a = 607.4(1) pm, b = 891.2(1) pm, c = 1201.0(2) pm, R 1 = 0.03). The characteristic unit is the bent [CuO 2 ] 3– complex (∠(O–Cu–O) = 170°). The reactivity of Na 5 [CuO 2 ](OH) 2 has been studied by DSC and in situ X‐ray diffraction techniques. IR spectroscopy has been used for further characterization. The Madelung Part of the Lattice Energy (MAPLE) has been calculated as well.
