Crystal Structure of β-Al2Te3The crystal structure of β-Ab2Te3 has been determined by means of single crystal x-ray diffractometry. The examined crystal can be described as a pseudomerohedric twin with a plane of reflection in (001) as twin element. The refinement in P21/c (No. 14) with the crystal parameters a = 7.181(1) Å, b = 12.848(3) Å. c = 14.167(3) Å, β = 90.04(2)°, V = 1307.1 Å3 and Z = 8 resulted in a final R-value (based on F) of 0.0245. β-Al2Te3 crystallizes in a layered arrangement and represents a new structure type.
Notes:
Die Kristallstruktur von β-Al2Te3 konnte auf der Grundlage von Einkristalldaten ermittelt werden. Der vermessene Kristall lag als pseudomeroedrischer Reflektionszwilling nach (001) vor. Die Verfeinerung in P21/c (Nr. 14) mit a - 7,181(1) Å, b = 12,848(3) Å, c = 14,167(3) Å, β = 90,04(2)°, V = 1307,1 Å3 und Z = 8 konvergierte gegen einen konventionellen R-Wert von 0,0245. β-Al2Te3 kristallisiert in einer Schichtstruktur und stellt einen neuartigen Strukturtyp dar.
