KInS2 crystallizes in a two dimensionally ordered structure, which is related to the TlGaSe2-type structure. High-resolution transmission electron microscopy (HRTEM) and the analysis of diffuse scattering give evidence for defined shifts between orde

The crystal structure of the monoclinic low tridymite MC, a polymorph of SiO2, has been re-refined using the unpublished as-measured intensities of a twinned crystal collected by Kato and Nukui [Acta Crystallogr. B32 (1976) 2486–2491]. Crystal data

The crystal structure of a multiple domain crystal of composition YbV4O8 has been determined and refined as a commensurate composite crystal with two subsystems. Subsystem 1 is formed by the V2O4 atoms, subsystem 2 contains the Yb atoms. All reflecti
