Bis[3-(anthracen-9-yl)pentane-2,4-dionato-κ2O,O′]-(N,N-dimethylformamiae-κO)[tris(pyrazol-1-yl-κN2)hyaroborato]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 pi-stacking interactions are limited to the edges of two anthracene rings.
