Bis[3-(anthracen-9-yl)pentane-2,4-dionato-κ2 O,O'](N,N-di-methyl-formamide-κO)[tris-(pyrazol-1-yl-κN 2)hydroborato]europium(III).

The title compound, [Eu(C9H10BN6)(C19H15O2)2(C3H7NO)] or [TpEu(Anthracac)2(DMF)], was synthesized by reaction of a tris-(pyrazol-yl)borate (Tp-) Eu3+ complex with 3-(anthracen-9-yl)pentane-2,4-dione (HAnthracac) in the presence of tri-ethyl-amine. In the title compound, Eu3+ is located in an octa-vertex square-pyramidal coordination environment. In the two Anthracac- ligands, the anthracene and nearly planar acetyl-acetonate fragments are almost orthogonal. Neighboring mol-ecules of TpEu(Anthracac)2(DMF) are connected in the crystal by inter-molecular van der Waals inter-actions, while π-stacking inter-actions are limited to the edges of two anthracene rings. © Mikhalyova et al. 2022.
