Jones, Morton Edward (1953) I. The Structures of Some Compounds of Boron. II. Some Other Structural Studies. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/BX25-TG82.


Section I contains a description of the structural investigations of several compounds of boron, using electron diffraction and X-ray diffraction techniques. The structure of stable pentaborane has been determined and the interatomic distances and bond angles have been derived. The structure of tetraborane has been found and approximate values for the parameters are given. A possible model for unstable pentaborane has been found. A magnesium boride, MgB[subscript 2], has been prepared and shown to be isomorphous with AlB[subscript 2]. A beryllium boride of approximate composition Be[subscript 2]B has been prepared in impure form and shown to have a structure similar to CaF[subscript 2]. An unsuccessful attempt has been made to prepare the copper boride Cu[subscript3]B[subscript 2] that is reported in the literature. Section II contains a description of some other electron diffraction and X-ray diffraction investigations. The interatomic distances and bond angle in formyl fluoride have been determined. A partially successful study has been made of ozone. A reinvestigation of copper silicide has removed the major portion of an unpleasant random feature of the previous structure. A method has been devised for simplifying the calculation of theoretical intensity curves containing temperature factored terms.
