Abstract

This work describes the preparations and properties of some new complexes of in¬dium (III). The ligands contain atoms from groups V and VI.
Indium (III) exhibits class “A” accepter hehaviour in which the strength of co- ordination is: N>P and 0>S.
Complexes of In (III) chloride and-bromide with organic ligands containing nitrogen or oxygen atoms as their potential sites of donation have been prepared.
The infrared of the formed complexes are discussed and an attempt to explain the type of coordinate bond is made. No evi- dence has been obtained for the formation of complexes with Me2S, Me2SO2, Ph2S, Ph2SO2, Ph3P or Ph3PS. This is probably because of the low donor strengths of sulphur and phosphorus atoms with respect to indium (III). Thermal stabilities of the ad- ducts, molecular weights and the conductance of their Solutions in organic solvents are measured.
The coordination chemistry of indium trihalides('), perchlo- rate(2), nitrate(3) and lower halidesl4) have been investigated. indi¬um (III), like the corresponding boron, aluminium, and gallium compounds, readily forms addition compounds with a variety of donor molecules.
The purpose of the present work is to study systematically the reactions of indium trichloride and-bromide with organic
