Kristallstruktur der stabilen Modifikation von SeCl4 / Crystal Structure of the Stable Modification of SeCl4

Abstract

Abstract Single crystals of the stable modification of selenium tetrachloride (α-SeCl4) were grown by sublimation, and the crystal structure was determined. As that of metastable β-SeCl4 it contains tetrameric cubane-like molecules Se4Cl4, but with different point symmetry and in positions which correspond to those of the atoms of the β-tungsten structure type.
