J. A. Viljoen, A. Muller and A. Roodt

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-trifluoroacetylacetonate 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 molecule. The crystal structure involves C-H.F hydrogen bonds.
