Abstract

The title compound, [Eu(CHBN)(CHO)(CHNO)] or [TpEu(Anthracac)(DMF)], was synthesized by reaction of a tris-(pyrazol-yl)borate (Tp) Eu complex with 3-(anthracen-9-yl)pentane-2,4-dione (HAnthracac) in the presence of tri-ethyl-amine. In the title compound, Eu 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)(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.
