From mystery to modulation: the structural story of Rb2[Si2O5]

Acta Crystallographica Section B, EarlyView.
The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...
