Conclusions
-
1.
Dihafniumoxane π-cyclopentadienyl compounds of the type: a) R2(C5H5)HfOHf(C5H5)R2 (R is a chelate residue of acetylacetone or 8-oxyquinoline); b) Br(C5H5)2HfOHf(C5H5)2Br, were produced.
-
2.
π-Cyelopentadienyl, chelate compounds of hafnium containing anionic groups: C5H6HfR2X, X= Cl, Br, ONO2 were synthesized.
-
3.
The IR spectra of π-cyclopentadienyl compounds of hafnium were measured and discussed.
