The complex TiCl 2 (acac) 2 is fluxional in solution, the NMR spectrum exhibiting a single methyl resonance at room temperature. [6] Unlike Ti(IV), both Zr(IV) and Hf(IV) bind four bidentate acetylacetonates, reflecting the larger radius of these metals. Hafnium acetylacetonate and zirconium acetylacetonate adopt square antiprismatic structures.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

Anhydrous nickel(II) acetylacetonate exists as molecules of Ni 3 (acac) 6. The three nickel atoms are approximately collinear and each pair of them is bridged by two μ 2 oxygen atoms. Each nickel atom has tetragonally distorted octahedral geometry , caused by the difference in the length of the Ni–O bonds between the bridging and non ...

Vanadyl acetylacetonate is the chemical compound with the formula VO(acac) 2, where acac – is the conjugate base of acetylacetone. It is a blue-green solid that dissolves in polar organic solvents. The coordination complex consists of the vanadyl group, VO 2+, bound to two acac – ligands via the two oxygen atoms on each.
