Homometallic titanium oxo clusters are one of the most important groups of metal oxo clusters, with more than 300 examples characterized by X-ray structure analyses. Most of them are uncharged and are obtained by partial hydrolysis and condensation of titanium alkoxo derivatives. The cluster cores, ranging from 3 to >50 titanium atoms, are stabilized by organic ligands. Apart from residual OR groups, carboxylato and phosphonato ligands are most frequent. The article critically reviews and categorizes the known structures and works out basic construction principles by comparing the different cluster types.
同金属氧代钛簇是金属氧代簇中最重要的类别之一，有300多个实例通过X射线结构分析得以表征。它们大多呈电中性，通过钛醇盐衍生物的部分水解和缩合反应获得。簇核含有3至50多个钛原子，由有机配体稳定。除了残留的OR基团外，羧基和膦酸酯配体最为常见。本文对已知结构进行了批判性综述和分类，并通过比较不同的簇类型总结出基本的构建原则。
