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.
