Chromium(III) acetylacetonate is the coordination compound with the formula Cr(C5H7O2)3, sometimes designated as Cr(acac)3. This purplish coordination complex is used in NMR spectroscopy as a relaxation agent because of its solubility in nonpolar organic solvents and its paramagnetism. See more The compound is prepared by the reaction of chromium(III) oxide with acetylacetone (Hacac): Cr2O3 + 6 Hacac → 2 Cr(acac)3 + 3 H2O The complex has idealized D3 symmetry. The Cr-O distances … See more Often paramagnetism in compounds is detrimental for NMR spectroscopy, as the spin-lattice relaxation times are very short which leads to … See more • Chromium(II) acetylacetonate See more
