Copper(II) acetylacetonate is the coordination compound with the formula Cu(O2C5H7)2. It is the homoleptic acetylacetonate complex of copper(II). It is a water-soluble bright blue solid. According to X-ray crystallography, the Cu center is square planar.[1] 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.[2]
