Copper(II) acetylacetonate is the

coordination compound A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the ''coordination centre'', and a surrounding array of chemical bond, bound molecules or ions, that are in turn known as ' ...

with the formula Cu(O₂C₅H₇)₂. It is the homoleptic acetylacetonate complex of copper(II). It is insoluble within water and exists as a bright blue solid. According to

X-ray crystallography X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to Diffraction, diffract in specific directions. By measuring th ...

, the Cu center is

square planar In chemistry, the square planar molecular geometry describes the stereochemistry (spatial arrangement of atoms) that is adopted by certain chemical compounds. As the name suggests, molecules of this geometry have their atoms positioned at the co ...

. Single crystals of this compound exhibit the unusual property of being highly flexible, allowing the formation of knots. The flexibility is attributed to the nature of the intermolecular forces.
