Bonds between In and Group VI Atoms

Compounds containing Bonds between In and Group VI Atoms.— 

Evaluation of apparent molar volumes leads to the identification of the [In(H20)6]3+ cation in aqueous solutions of non-complexing mineral acids.554 In aqueous HC1 or HBr, mixed halogeno-aquo complex cations are produced, i.e. [In(H20)5Cl]2+ etc. 

Dimethylindium carboxylates are formed from Me3In,OEt2 + acid in Et20.555 I.r. spectra of these compounds show that the carboxylate groups are bidentate. 

spectra of the vapour over indium and thallium metaborates can be assigned to monomeric species MB02, which have a cyclic structure (76).556
