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.
