“…One would not expect major changes in the luminescence spectra when the 2,2'-bipyridine (bipy) ligand is replaced by 4,4'- [159]. The same remark can be made for complexes of -diketonates [275,653]. Recently, high-resolution luminescence spectroscopy was used to investigate how doping of Eu 3+ ions into -NaYF 4 and -NaYF 4 distorts the local crystallographic symmetry of the host matrix [315].…”

“…β-Diketonate ligands have been widely used to construct different lanthanide complexes for their luminescence properties or they are used as precursors of metalorganic chemical vapor deposition for single and multi-component oxide thin lms [3][4][5]. Herein, we report the crystal structure of a dinuclear Ce(III) complex with 1,3-bis(4,4,4-tri uoro-1,3-dioxobutyl)phenyl.…”

CCDC no.: 1443565The asymmetric unit of the title crystal structure is shown in the gure. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters. Source of materialThe title compound was synthesised following a literature method [1,2]. In a typical reaction, to a solution of 6-methoxy-2,3-dihydro-1H-inden-1-one (2.5 g, 11.57 mmol) in 60 mL dry tetrahydrofuran, ethyl 2,2,2-tri uoroacetate (2.46 g, 17.31 mmol) was added, and the mixture was allowed to stir for 45 min. Then NaH (0.555 g, 13.88 mmol) was added, and the mixture was allowed to stir for 48 h at room temperature under a N 2 atmosphere. The resulting mixture was poured into 100 mL water and acidi ed to pH 2-3 using 2 N hydrochloric acid. Then the mixture was extracted with dichloromethane (3 × 10 mL) and the combined organic extracts were dried with anhydrous Na 2 SO4. The solvent was removed by rotary evaporation and the yellow residue was dried under vacuum. The blocked-shaped crystals of the title compound were obtained in about 5 days by recrystallization from hexane. Experimental detailsAll H atoms on C atoms were placed in idealized positions [C-H = 0.97 (methylene) and 0.93 Å(aromatic)] and included in the re nement in the riding-model approximation, with U iso (H) = 1.2Ueq(methylene and aromatic C). The title structure was solved by direct methods and re ned by full-matrix least-squares on F 2 using the SHELXTL program package [3].The tri uoromethyl group shows disorder which is for clarity not shown in the gure.
