Abstract

In the middle of the last century the stereochemistry of divalent copper atoms was mostly unknown. Crystal structure investigations of trippkeite, azurite, linarite, or teineite led Josef Zemann (1923-2022) to understand the coordination figures controlled by the Jahn-Teller-effect. In contrast to the earlier thought CuO₆ octahedra, he described the coordination figures as planar [4], tetragonal pyramidal [4+1], and tetragonal dipyramidal [4+2] (Zemann 1961; 1972). The additional ligands have none or only a minor influence on the geometry of the CuO₄ square. In honour to these pioneering investigations, two further compounds with Cu²⁺ ions are presented here: Cu(SeO₄) and Cu(SeO₃OH)₂∙6H₂O. They were synthesized at low-temperature hydrothermal conditions (220 °C) and room temperature, respectively.
