Abstract

In the title compound, [Hf(C5H4F3O2)4]·2C7H8, 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.
