| Abstract: | Synthesis and Crystal Structure of LiHSO4 Single crystals of the new compound LiHSO4 are synthezised from the system Lithiumsulfate/Sulfuric acid. The up to day not determined structure of the title compound is monoclinic, space group P21/c with the lattice constants a = 5.234(2), b = 7.322(1) and c = 8.363(1) Å, b? = 90.02(2)°. The volume of the unit cell has been determined to V = 320.5 Å3, the number of formula units to Z = 4 and the density to Dx = 2.156 g cm?3. There are crystallographically identical SO3(OH)- and LiO4-tetrahedra in the structure. Every tetraheda is linked to four different tetrahedra of the other sort. Two neighboured LiO4 terahedra form a common edge. In that way layers are formed running parallel the yz-plane. These layers are connected over hydrogen bonds. |
