Abstract/Summary:
Research into crystalline matter has long been of interest to humanity, both in order to advance our society by creating new technologically useful materials and in order to better understand to nature of the properties we depend on for so much of our existing technology. In recent decades, solution-based crystal growth syntheses including hydrothermal and molten flux techniques have risen to the forefront of solid-state chemistry as superior methods of synthesizing new materials as single crystals ripe for structure determination and property measurements.;This work seeks to educate readers on recent advances in the hydrothermal realm of crystal growth: namely facile routes to the synthesis of transition-metal fluorides, uranium fluorides, and uranium oxides and compounds of related oxoanions (hydroxides, phosphates, phosphites). Work was done to characterize these new materials as completely as possible, and to work towards the goal of unraveling the structural contribution to magnetism in uranium compounds, namely how the coordination number of U(IV) affects the transition (or lack thereof) from the triplet to the nonmagnetic singlet ground state.
