%X The thermal decomposition of yttrium(III) hexanoate (Y(C<sub>5</sub>H<sub>11</sub>CO<sub>2</sub>)<sub>3</sub>)·xH<sub>2</sub>O in argon was studied by means of thermogravimetry, differential thermal analysis, IR-spectroscopy, X-ray diffraction at a laboratory Cu-tube source and in-situ experiments at a synchrotron radiation source as well as hot-stage optical microscopy. Dehydration occurs between 40 °C and 110 °C and is accompanied by a transition from solid to liquid crystalline state. At the onset of the main decomposition stage of the anhydrous Y(C<sub>5</sub>H<sub>11</sub>CO<sub>2</sub>)<sub>3</sub>), solidification takes place in the 315–335 °C range. Y(C<sub>5</sub>H<sub>11</sub>CO<sub>2</sub>)<sub>3</sub>) decomposes in a single step into Y<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> with release of CO<sub>2</sub> and 6-undecanone between 280 °C and 490 °C. A side reaction appears to yield elemental carbon and volatile decane (C10H22). Y<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> is converted to Y<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> with release of CO<sub>2</sub> between 500 °C and 975 °C.
