✦ Synopsis
The distortion from the octahedral geometry is discussed for Indium(III) 1,1-dithio complexes (dithiophosph(in)ates, dithiocarbamates, dithioarsinates) and isostructural chromium(III) compounds in relation with the bite of the ligands, the S ´´´S repulsion within the four members rings and S ´´´S interligand distances. The crystal and molecular structures of In(S 2 AsR 2 ) 3 (R = Me, Ph) have been determined by single crystal X-ray diffraction. The dithioar-sinate ligands are basically monomeric and isobidentate, with average values for arsenic-sulphur bond distances of 2.135 A Ê for dimethyl and 2.137 A Ê for diphenyl complex. The average In±S distances are identical (2.634 A Ê ) in both cases.
