Bis[3-(anthracen-9-yl)pentane-2,4-dionato-κ²O,O′](N,N-dimethylformamide-κO)[tris(pyrazol-1-yl-κN²)hydroborato]europium(III).

The title compound, [Eu(C₉H₁₀BN₆)(C₁₉H₁₅O₂)₂(C₃H₇NO)] or [TpEu(Anthracac)₂(DMF)], was synthesized by reaction of a tris(pyrazolyl)borate (Tp^-) Eu³⁺ complex with 3-(anthracen-9-yl)pentane-2,4-dione (HAnthracac) in the presence of triethylamine. In the title compound, Eu³⁺ is located in an octavertex square-pyramidal coordination environment. In the two Anthracac-ligands, the anthracene and nearly planar acetylacetonate fragments are almost orthogonal. Neighboring molecules of TpEu(Anthracac)2(DMF) are connected in the crystal by intermolecular van der Waals interactions, while π-stacking interactions are limited to the edges of two anthracene rings.
