Abstract

The crystal structure of the tris(1,2-ethanediol) complex of copper sulphate was redetermined to study the conformations of 1,2-ethanediol molecule around the CO axes. In all 1,2-ethanediol molecules one of the OH hydrogen atoms is in nearly antiperiplanar (trans) position (173.0, 182.3, 196.1°) to the remote C atom. The second OH hydrogen atoms in the molecules are placed in synclinal (gauche, 66.1°), nearly synclinal (84.9°) and antiperiplanar (239.5°) position to the remote C atoms. The tetragonally distorted octahedral coordination sphere determined by crystallography was supported by EPR spectral. A weak superexchange coupling was suggested on the basis of the magnetic susceptibility measurements in the 4.2-490 K temperature range.
