Transition metal -oxo clusters find increasing interest in material science as nanosized building blocks, especially for inorganic-organic hybrid materials. When polymerizable ligands are attached to the cluster surface, the inorganic building blocks can be incorporated in polymers by covalent bonding. Numerous transition metal-oxo clusters with polymerizable ligands were synthesized and used to obtain polymers with tailored properties.
A versatile route to such clusters is by reactions of transition metal alkoxides with carboxylic acids, whereby cluster size and shape is determined by the alkoxide/acid ratio, the kind of carboxylic acid and the kind of alkoxo groups.
During the last decade mainly carboxylic acids were used for cluster synthesis. The change from bidentate carboxylic acids to potentially tridentate ligands for the cluster synthesis can widen the range of structural possibilities.
In this work we present the synthesis and structure of a new type of Titanium-oxo cluster based on phenylsulfonic acid.
