Abstract
Tin (IV) and zirconium (IV) chlorides form coloured complexes with benzanthrone, anthrone, nitroanthrone and benzalanthrone and the corresponding bromides with benzathrone only in non-aqueous solvents in the ratio 1:2. The iodides do not form adducts with these anthrones. Tin (IV) halide complexes are non-ionic and monomeric in nitrobenzene. The 1:2 adducts decompose into thermally unstable 1:1 products on heating. Studies on the i.r. spectra of these complexes reveal the complex formation through carbonyl oxygen and the following relative order of Lewis acid strengths: chloride > bromide > iodide and tin > zirconium.
