Thesis (M.A.)--Boston University The x-ray diffraction study of pyridine-boron trichloride undertaken here constitutes the beginning of a structure determination which will eventually result in a complete knowledge of bond distances and bond angles within the molecule and knowledge of the packing of molecules within the crystal. The 1:1 addition compound pyridine-boron trichloride was first reported by Gerrard and Lappert. Greenwood and Wade were among the first to study the physical properties of pyridine-boron trichloride. In the absence of direct evidence as to what ions are present and the extent of dissociation, four possible structures were inferred for pyridine-BCl3. [Py2BCl2]+[BCl4]- was considered the most favorable for the molten state. However, a detailed examination of the infrared spectrum of the solid shows that the structure is probably more consistent with the formula C5H5N -> BCl3. This was also the structure found by Zvonkova for pyridine-boron trifluoride [TRUNCATED] 2017-11-01T12:34:04Z 2017-11-01T12:34:04Z 1962 1962 Thesis/Dissertation b14565225 https://hdl.handle.net/2144/24356 en_US Based on investigation of the BU Libraries' staff, this work is free of known copyright restrictions.
