Indium acetylacetonate, [(CH₃.CO)₂CH]₃In

Indium acetylacetonate, [(CH₃.CO)₂CH]₃In, is .prepared by heating indium hydroxide for eight hours with a boiling alcoholic solution of acetylacetone. It crystallises from alcohol in flat, six-sided prisms and melts at 183°; the crystals are rhombic (bipyramidal) and isomorphous with scandium and ferric acetylacetonates. At 260° to 280° it partly sublimes and partly decomposes. Its molecular weight in ethylene dibromide solution is in accordance with the above simple formula.
