Abstract
The crystal structure of mercury(II) chromium(III) tetroxide has been redetermined from a single crystal grown from an HgO–CrO3 mixture at 743 K in an evacuated silica ampoule. The present investigation confirms the previous study, which was based on powder data [Wessels, Czekalla & Jeitschko (1998). Mater. Res. Bull. 33, 95–191], but with higher precision and with all displacement parameters refined anisotropically. HgCr2O4 adopts the normal 2–3-spinel structure, with mercury in one-eighth of the tetrahedral and chromium in one-half of the octahedral voids of the cubic closed-packed O atoms.
