Abstract

The monoclinic phase of TCNE (C6N4) was submitted to a new X-ray and neutron diffraction analysis. Contrary to the results reported by Bekoe and Trueblood (1960) we found a slight disorder, such that 3.8 – 5% of the molecules are rotated about 90 degrees in the molecular plane around their center of gravity. The final R-values are 0.035 for the X-ray- and 0.033 for the neutron-data. The resulting X – N-map showed clearly resolved peaks, whose hights correspond well with theoretical calculations.
