An electron diffraction study of gaseous dichlorine monoxide. The rg distances and their vibrational amplitudes

Abstract

The electron diffraction pattern from dichlorine monoxide vapour at 22° has been recorded on the Glasgow apparatus and intensity data have been obtained over the range s= 1·06 to 39·60 Å^–1. Data processing and structure refinement were carried out on the KDF9 computer at Glasgow. The least-squares refinement gave the following structural parameters: r_g(1) for Cl–O = 1·693 Å, r_g(1) for Cl ⋯ Cl = 2·795 Å, u_ClO= 0·053 Å, and u_ClCl= 0·067 Å. The reproducibilities are 0·003, 0·004, 0·003, and 0·003 Å respectively. The vibrational amplitudes are in good agreement with the values calculated from spectroscopic data.
