Chromium(II) acetylacetonate

Chemical compound

Chromium(II) acetylacetonate is the coordination compound 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, the Cr center is square planar.^[1] In contrast to the triplet ground state for this complex, the bis(pyridine) adduct features noninnocent acac^2- ligand attached to Cr(III).^[2]
