Abstract :
The mononuclear title complex, [Eu(C24H34O4P)3(CH4O)5]·CH4O, (1), has been obtained as a minor product in the reaction between EuCl3(H2O)6 and lithium bis(2,6-diisopropylphenyl) phosphate in a 1:3 molar ratio in a methanol medium. Its structure exhibits monoclinic (P21/c) symmetry at 120 K and is isostructural with the La, Ce and Nd analogs reported previously [Minyaev et al. (2018a[Minyaev, M. E., Tavtorkin, A. N., Korchagina, S. A., Bondarenko, G. N., Churakov, A. V. & Nifant'ev, I. E. (2018a). Acta Cryst. C74, 590-598.]). Acta Cryst. C74, 590–598]. In (1), all three bis(2,6-diisopropylphenyl) phosphate ligands display the terminal κ1O-coordination mode. All of the hydroxy H atoms are involved in O—H⋯O hydrogen bonding, exhibiting four intramolecular and two intermolecular hydrogen bonds. Photophysical studies have demonstrated luminescence of (1) with a low quantum yield.
