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 acac2- ligand attached to Cr(III).[2]
