Chromium(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 Cr(O₂C₅H₇)₂. It is the homoleptic acetylacetonate complex of chromium(II). It is an air-sensitive, paramagnetic yellow-brown 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 Cr 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 ...

. In contrast to the triplet ground state for this complex, the bis(pyridine) adduct features noninnocent acac^2- ligand attached to Cr(III). Chromium(II) acetylacetonate is prepared by treating

chromous acetate Chromium(II) acetate hydrate, also known as chromous acetate, is the coordination compound with the formula Cr2(CH3CO2)4(H2O)2. This formula is commonly abbreviated Cr2(OAc)4(H2O)2. This red-coloured compound features a quadruple bond. It exists ...
