The single-crystal structures of two incommensurate compounds, Ba1+x[(CuxRh1-x)O3] with x = 0.1605 and x = 0.1695, were solved by a general method using the superspace group approach. A saw-tooth function was used to model both the occupational and displacive modulations. This approach requires very few refineable parameters and leads to low residuals, R = 0.0370 and R = 0.0330 for x = 0.1605 and x = 0.1695, respectively. The idealized structures of these two compounds consist of [(CuxRh1-x)O3]∞ chains containing groups of five face-shared (RhO6) octahedra separated by (CuO6) trigonal prisms. These chains in turn are separated from each other by [Ba]∞ chains. The idealized composition of both phases is Ba7CuRh5O18. Their modulated struc...
