Abstract
The title compound, [Ni(C5HF6O2)(2)(C2H3N)(2)], was obtained as an unintentional by-product in the reaction of Ni(hfac)(2) (hfac is hexafluoroacetylacetonate) with pyrazine N,N'-dioxide in acetonitrile. The molecule is centrosymmetric and the ligands are trans to one another, with the Ni-II atom on a position with 2/m symmetry. The CF3 groups are in a symmetry-imposed eclipsed conformation. The acetonitrile methyl group is involved in weak non-classical C-H center dot center dot center dot O intermolecular hydrogen bonding to the propanedionate O atoms. This forms a chain synthon parallel to the b axis. The chains are further arranged into sheets parallel to the bc plane.
