Abstract 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 dithioarsinate ligands are basically monomeric and isobidentate, with average values for arsenic‐sulphur bond distances of 2.135 Å for dimethyl and 2.137 Å for diphenyl complex. The average In–S distances are identical (2.634 Å) in both cases.
