چکیده
The title compound, [Zn(C(8)H(10)F(3)O(2))(2)(CH(4)O)(2)], is a dimethanol coordinated zinc complex with the acetyl acetonate derivative 1,1,1-trifluoro-5,5-dimethyl-hexane-2,4-dionate. The bis--β-diketonate complex, which is isostructural with its Co analogue, is located on a crystallographic inversion center. The complex is octa-hedral with basically no distortion, and the methanol mol-ecules are in trans positions with respect to one another. The planes of the β-diketonate and the ZnO(4) unit are tilted by 18.64 (10)° against each other. O-H⋯O hydrogen bonds between the methanol hydroxyl groups and neighboring diketonate O atoms create chains running along [100].
