Abstract
Tetrakis(benzoylacetonato)cerium(IV), [Ce(bzac)4] and triethylammonium tetrakis(benzoylacetonato)lanthanate(III) tetrahydrate, [Et3NH][La(bzac)4] · 4H2O were prepared and characterized by TG and DCS measurements, IR spectroscopy, and X-ray structure analysis. The coordination polyhedron of cerium is a trigonal dodecahedron, while that of lanthanum is a distorted square antiprism. Thermal and spectroscopic measurements indicate that bonding of the ligand to metal is stronger in [Ce(bzac)4] than in [La(bzac)4]−.
