An X-ray and neutron diffraction study of mercury(II) sulphate monohydrate
Description
The structure of HgSO4.H2O has been reinvestigated with both X-ray and neutron diffraction methods and refined to R=0.040 (X-rays) and R=0.032 (neutrons). The crystals are orthorhombic, space group Pnma, with a=7.8796 (9), b=5.4209 (4), c=8.9704 (7) A, Z=4. The Hg atom is coordinated to one sulphate O atom and one water molecule forming discrete HgSO4.H2O groups, connected by hydrogen bonds to form a three-dimensional structure. Four more distant O atoms of different sulphate tetrahedra complete an irregular octahedron around Hg. In the water molecule the O-H distances are 0.931 (9) and 0.955 (5) A and the angle is 108.0 (6)0. (Auth.)
