W. Mellor, published by Longmans, Green and Company, London, 1941, page 388〕 Mercury(I) sulfate is a metallic compound that is white, pale yellow or beige powder.〔http://www.chemicalbook.com/ChemicalProductProperty_EN_CB0259783.htm〕 It is a metallic salt of sulfuric acid formed by replacing both hydrogen atoms with mercury(I). It is highly toxic; it could be fatal if inhaled, ingested, or absorbed by skin. ==Structure== The crystal structure of mercurous sulfate is made up of Hg22+ dumbbells and SO42− anions as main building units. Hg22+ dumbbell is surrounded by four Oxygen atoms with Hg₋O distance ranging from 2.23 to 2.93 Å, whereas Hg-Hg distance is approximately 2.500Å.〔''Preparation and Characterization of Dimercury(I)Monofluorophosphate(V), Hg2PO3F: Crystal Structure, Thermal Behavior, Vibrational Spectra, and Solid-State 31P and 19F NMR Spectra'' by Matthias Weil, Michael Puchberger, and Enrique J. Baran, published by Inorg. Chem. 2004, 43. pages 8330-8335〕 Studies have shown mercury(I) sulfate to have the mercury atoms arranged in doublets with a bond distance of 2.500Å. The metal atom doublets are oriented parallel to the an axis in a unit cell. Mercury doublets form part of infinite chain SO4 - Hg - Hg - SO4 - Hg - Hg - … The Hg - Hg - O bond angle is 165°±1 . The chain crosses the unit cell diagonally. The mercury sulfate structure is held together by weak Hg-O interactions. The SO4 does not act as a single anion, but rather coordinated to the mercury metal.〔Dorm, E. 1969. Structural studies on mercury(I) compounds. VI.
