ABSTRACT
In the title compound, [Hf(C(5)H(4)F(3)O(2))(4)]·2C(7)H(8), the Hf(IV) atom, lying on a twofold rotation axis, is coordinated by eight O atoms from four 1,1,1-trifluoro-acetyl-acetonate ligands with an average Hf-O distance of 2.173 (1) Å and O-Hf-O bite angles of 75.69 (5) and 75.54 (5)°. The coordination polyhedron shows a slightly distorted Archimedean square antiprismatic geometry. The asymmetric unit contains a toluene solvent mol-ecule. The crystal structure involves C-H⋯.F hydrogen bonds.
