Abstract: The title compound, [Ce(C₁₂H₁₄F₃O₂)₂(C₆H₁₈NSi₂)(C₆H₁₅N₃)], is a rare example of a structurally characterized lanthanide(III) camphorate. The Ce^III atom shows a distorted trigonal-dodecahedral coordination, formed by the N atom of the amido ligand [Ce-N = 2.428 (5) Å], four O atoms of two [eta] ²-bonded camphorate groups [average Ce-O = 2.459 (4) Å] and three N atoms of a chelating triazacyclohexane donor [average Ce-N = 2.808 (6) Å].
