A report on the crystallographic characteristics of the acetylacetone derivatives of aluminium, gallium, indium, scandium and iron has been contributed by T. V. Barker to a paper by Morgan and Drew ('Trans. Chem. Soc.,' vol. 119, p. 1059 (1921)). For the sake of convenience his table is reproduced here. This table shows how the tervalent acetylacetones present collectively a remarkable case of isotrimorphism. With the object of revealing the nature of this isotrimorphism and, if possible, of throwing light on the molecular structure of the acetylacetones, five of the crystals mentioned above and five others have been submitted to an X-ray examination. The results may first of all be tabulated after the manner of Barker's.
