Abstract
This dissertation presents the excision of Zr-based clusters from cluster-containing extended phases. The details of the methods for cluster excision we have developed are presented and possible future directions outlined. A number of zirconium clusters were excised using DMSO$sb2$, sulfolane, or a room temperature chloraluminate melt--1-ethyl-3-methyl imidazolium chloride/aluminum trichloride melt. Excision reactions were successful from the solid phases $rm LiZrsb6Clsb{15}Fe$, $rm Zrsb6Clsb{14}Fe$, $rm Zrsb6Brsb{14}Fe$, and $rm Lisb2Zrsb6Clsb{15}Mn$. Some results of cluster excision using acetonitrile above its boiling point are presented as well. Characterization of the excised cluster was carried out using electronic absorption spectroscopy and, where possible, single crystal X-ray diffraction.
