| Abstract: | Synthesis and Crystal Structure of Metal(I) Hydrogen Sulfates – Ag(H3O)(HSO4)2, Ag2(HSO4)2(H2SO4), AgHSO4, and Hg2(HSO4)2 Hydrogen sulfates Ag(H3O)(HSO4)2, Ag2(HSO4)2 · (H2SO4), and AgHSO4 have been synthesized from Ag2SO4 and sulfuric acid. Hg2(HSO4)2 was obtained from metallic mercury and 96% sulfuric acid as starting materials. The compounds were characterized by X‐ray single crystal structure determination. Ag(H3O)(HSO4)2 belongs to the structure type of Na(H3O)(HSO4). The silver atom is coordinated by 6 + 2 oxygen atoms. In the structure, there are dimers and chains of hydrogen bonded HSO4– tetrahedra. Dimers and chains are connected by the H3O+ ion to form a three dimensional hydrogen network. Ag2(HSO4)2(H2SO4) crystallizes isotypic to Na2(HSO4)2(H2SO4). The coordination number of silver is 6 + 1. The structure of Ag2(HSO4)2(H2SO4) is characterized by hydrogen bonded trimers of HSO4– tetrahedra, which are further connected to chains. For the recently published structure of AgHSO4 the hydrogen bonding system was discussed. There are tetrameres and chains, connected by bifurcated hydrogen bonds. The structure of Hg2(HSO4)2 contains Hg22+ cations with Hg–Hg distance of 2.509 Å. Every mercury atom is coordinated by one oxygen atom at shorter distance (2.18 Å) and three ones at longer distances (2.57 to 3.08 Å). The HSO4– tetrahedra form zigzag chains by hydrogen bonds. |
