Hexafluoroacetylacetone complexes

Deposition of high quality copper films with a resistivity of less than 2.0 and deposition rates of 80-180 nm./min. is achieved at 250 C. using the hexafluoroacetylacetonate complex Cu(hfac)2 with H2 at 760 torr as carrier gas and reducing agent (74) ...

The zinc complex of 1,1,1,5,5,5-hexafluoroacetylacetonate forms coordination polymers in reaction with either 2,5-bis(4-ethynylpyridyl)furan or l,2-bis(4-ethynylpyridyl)benzene. The X-ray crystal structures demonstrate an isotactic helical structure for the former and a syndio-tactic structure for the latter in the solid state. Low-temperature 1H and 19F NMR studies gave information on the solution structures of oligomers. Chiral polymers were prepared from L2Zn where L = 3-((trifluoromethyl)hydroxymethylene)-(+)-camphorate. Reaction with 2,5-bis(4-ethy-nylpyridyl)furan gave a linear zigzag structure and reaction with tris(4-pyridyl)methanol a homo-chiral helical polymer.479...

The chemistry of the doubly hydrated form of hexafluoroacetylacetone, 1,1,1,5,5,5-hexafluoro-pentane-2,2,4,4-tetraolato (hfpt), is worth mentioning. A dinuclear manganese(III) complex (pyH)2[Mu2(hfpt)(hfacac)4] (130) was formed from a mixture of [Mn30(0Ac)6(py)3](C104),...
