The crystal structure of the complex formed between acetone and bromine has been determined between 14 K and 200 K. The structure exhibits negative 2D thermal expansion at low temperature and colossal thermal expansion in the perpendicular dimension. At low temperature the CO bond is significantly longer than that observed in free acetone.
