Abstract

TiO·5DMSO(ClO4)2, ZrO·8DMSO(ClO4)2 and Th·12DMSO(ClO4)4 are prepared by reaction of the respective metal perchlorates with an excess of dimethyl sulphoxide. The last two complexes yield ZrO·6DMSO(ClO4)2 and Th·6DMSO(ClO4)4 on heating around 185°C, while the titanyl complex explodes at 190°C. The extra DMSO molecules in the zirconyl and thorium complexes seem to be held in the lattice. In the parent complexes, the co-ordinated DMSO molecules are bonded by oxygen to the metal atoms while in the DMSO complexes of zirconyl and thorium perchlorates, obtained by heating at 185°C, the bonding involves the sulphur, indicating a change in the bonding during the process of heating.
