Di-μ-hydroxido-bis[tris(1,1,1,5,5,5-hexa­fluoro­acetyl­acetonato-κ(2) O,O′)hafnium(IV)] acetone solvate

The binuclear title compound, [Hf(2)(C(5)HF(6)O(2))(6)(OH)(2)]·C(3)H(6)O, contains an Hf(IV) atom which is eight coordinated and surrounded by three chelating β-diketonato 1,1,1,5,5,5-hexa­fluoro­acetyl­acetonate (hfaa) ligands and two bridging OH groups situated on a twofold rotation axis. The HfO(8) coordination polyhedron shows a slightly distorted Archimedean square anti-prismatic coordination with average Hf—O, C—O, C—C(Me) distances of 2.19 (2), 1.26 (2) and 1.49 (2) Å, respectively, and an O—Hf—O bite angle of 75.3 (5)°. Weak O—H⋯O hydrogen bonding inter­actions are observed between one of the bridging hydr­oxy groups and the disordered solvent mol­ecule.
