The twinned crystal structure of mu-2,2'-bipyrimidine-1kappa2N1,N1':2kappa2N3,N3'-bis{tris[4,4,4-trifluoro-1-(2-thienyl)butane-1,3-dionato-kappa2O,O']terbium(III)} ethyl acetate solvate.
The title compound, [Tb2(C24H12F9O6S3)2(C8H6N4)].C4H8O2, has two terbium(III) centers bridged by the polyazine ligand 2,2'-bipyrimidine (bpm), which is distorted from planarity by 7.0 (2) degrees . The terminal ligand 4,4,4-trifluoro-1-(2-thienyl)butane-1,3-dione (tta) is bidentate, coordinating through the two O atoms, while the bridging ligand is bis-bidentate, coordinating through four equivalent N atoms. Both the complex and the ethyl acetate solvent molecules are disordered. The structure was refined as a non-merohedral twin.
