Abstract
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.Keywords
