Ba[1+x]Ni[x]Rh[1−x]O[3] in superspace: modulated composite versus modulated-layer structure

What is it about?

The structure has been analyzed at room temperature within the (3+1)-dimensional superspace approach applying two different models: the compound is refined as modulated composite as well as modulated-layer structure.

Why is it important?

In both models discontinuous atomic domains are applied to describe the structural modulations. While the first approach stresses the pseudo-one-dimensional constitution, the latter highlights the layered character of these structures.
