The three-dimensionally modulated incommensurate crystal structure of lazurite from the Baikal region was determined for the first time. The structure was solved within the cubic system with the unit-cell parameter a cub = 9.077(1) and the (3+2)-dimensional superspace group Pnn 2 ( q 1 , q...

Such intergrowths indicate a continuous framework with different regions of the crystal containing different ordering and chemistries. Two new lazurite superstructures were observed with dimensions of 6d110 × 3d001, and 3d112 × 3d111 with respect to the cubic subcell....

CRYSTAL structureLazurite and other lazurite-related minerals (LRMs) containing sulfur in both sulfate and sulfide forms are sodalite-type compounds with various extraframework species, of which the tendency to order leads to structural modulations with a period that is either commensurate or...
