The crystal structure of germanium dibromide*
Veröffentlicht/Copyright:
28. Juli 2010
Abstract
Germanium dibromide (GeBr2) is monoclinic, P21/c, with a = 11.68, b = 9.12, c = 7.02 Å, β = 101.9°, and eight formula weights per cell. The crystal structure as determined by x-ray diffraction consists of layers of edge-sharing distorted GeBr6 octahedra parallel to {100} with bromine bridges linking the layers. Distortion of the octahedra gives rise to chains of vertex-sharing GeBr3 trigonal pyramids within the octahedral layers. The octahedral distortion in GeBr2 and other germanium halides may be an example of the second-order Jahn-Teller effect.
