The first has density 2.205 and the second 2.124. They are made by dissolving the nickel trifluoroacetate tetrahydrate in trifluoroacetic acid either anhydrous or 1% hydrated. [22] Nickel naphthenate is used as a fuel additive to suppress smoke, [23] as a rubber catalyst and as an oil additive.

Nickel tetrafluoride is an extremely strong oxidizer. The oxidizing properties are enhanced in presence of Lewis acids in anhydrous HF. In terms of oxidizing power, it is comparable to krypton difluoride. It can oxidize bromine pentafluoride to hexafluorobrome(VII) cation, potassium hexafluoroplatinate(V) to platinum(VI) fluoride.

Trifluoroacetic acid (TFA) is a synthetic organofluorine compound with the chemical formula CF 3 CO 2 H. It is a haloacetic acid, with all three of the acetyl group's hydrogen atoms replaced by fluorine atoms.
For simple carboxylates, the acetate complexes are illustrative. Most transition metal acetates are mixed ligand complexes. One common example is hydrated nickel acetate, Ni(O 2 CCH 3) 2 (H 2 O) 4, which features intramolecular hydrogen-bonding between the uncoordinated oxygens and the protons of aquo ligands. Stoichiometrically simple ...
Ethyl trifluoroacetate can be obtained by reacting 2,4,6-tris-(trifluoromethyl)-1,3,5-triazine with ethanol in the presence of hydrochloric acid. The former, in turn, can be prepared by a two-step reaction starting from trichloroacetonitrile by reaction with hydrogen chloride and fluorination of the intermediate with antimony trifluoride.
Nickel octahedra are shown in green, black spheres represent the carbon atoms of the organic linker and red spheres the oxygen of adsorbed water molecules. While surface area and pore volume is important to the adsorption properties of MOF materials, another consideration is the availability of coordinatively unsaturated metals sites.
