Hafnium acetylacetonate


Hafnium acetylacetonate, also known as Hf4, is a coordination compound with formula Hf4. This white solid is the main hafnium complex of acetylacetonate. The complex has a square antiprismatic geometry with eight nearly equivalent Hf-O bonds. The molecular symmetry is D2, i.e., the complex is chiral. It is prepared from hafnium tetrachloride and acetylacetone, and base. Zr4 is very similar in structure and properties.

Uses

Along with titanium tetrabutoxide, hafnium acetylacetonate serves as a catalyst for the production of poly.
