The Sr1.32Mn0.83Cu0.17O3 compound has been prepared by solid state reaction in an evacuated sealed silica tube at 1000 °C. The crystal structure of Sr1.32Mn 0.83Cu0.17O3 was studied by means of electron diffraction, high resolution electron microscopy and was refined from X-ray powder diffraction data (RI = 0.042, RP = 0.016). The compound belongs to the A3m+3nA′nB 3m+nO9m+6n family of hexagonal perovskites. Its incommensurate composite structure (a = 9.5964(1) Å, c = 2.6001(1) Å, q = 0.66159(3)c*, superspace group R3m(00γ)0s) consists of the modulated [(Mn,Cu)O3] and [Sr] subsystems. The repeat period along the [(Mn,Cu)O 3] chains of the BO6 octahedra and the A′O6 trigonal prisms is equal to 99 polyhedra and can be represented as a sequence of 1 × (3 oct + 1 prism) and 9 × (2 oct + 1 prism) or 10 × (2 oct + 1 prism). Mn is located at the octahedral sites, whereas the trigonal prismatic sites are randomly occupied by Mn and Cu.
