Goldish, Elihu (1956) I. The Molecular Structures of Certain Organic Four-Membered Ring Compounds. II. The BaMg₉ Structure. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/DRDJ-XF36.


Part I presents the results of electron diffraction investigations of some relatively simple four-membered organic ring compounds: trimethylene oxide, 3-methylenetrimethylene oxide, trimethylene sulfide, and cyclobutene. Discussion is given of the bond lengths in these and other small-ring molecules. In a supplementary section are the results of an investigation of dimethyl selenide, which indicates a somewhat larger radius for selenium than is usually given, and preliminary results for decaborane. In Part II the disordered BaMg9 structure is investigated and discussed. It can be described on the basis of a CaCu5-type structure in which about half the barium atoms are replaced by pairs of magnesium atoms.
