The structure of diaqua (15-crown-5) copper (II) dinitrate described in (3+1)-dimensional superspace

Diaqua (15-crown-5) copper (II) dinitrate is an organic salt presenting an one-dimensional commensurate modulation. The diffraction pattern is characterized by strong Bragg reflections and weaker superstructure reflections (satellites). The structure is described in the superspace formalism as a modulated structure in (3 + 1) dimensions with occupational and displacive modulation functions.
