| Summary: | The binuclear molecule of the title compound, [Hf2(C10H6F3O2)6(OH)2]·2C3H7NO, lies across an inversion centre and contains a HfIV atom which is eight-coordinated and surrounded by three chelating β-diketonato tris(4,4,4-trifluoro-1-phenylacetylacetonate (tfba−) ligands and two bridging OH− groups in a distorted square-antiprismatic geometry. The Hf—O bond lengths vary from 2.073 (2) to 2.244 (2) Å and the O—Hf—O bite angles vary from 73.49 (9) to 75.60 (9)°. Weak O—H...O hydrogen-bonding interactions are observed between the bridging hydroxy groups and the dimethylformamide solvent molecules. The unit cell contains solvent-accessible voids of 131 Å3, but the residual electron density in the difference Fourier map suggests no solvent molecule occupies this void. |
