Abstract : The report is divided into four sections: Photo-electron spectroscopy of dimethyl aminohaloboranes; 11B nuclear magnetic resonance data for the boron trihalides and mixed trihalides; Mass spectrometric studies on compounds Me4M and Me3M-M(1)Me3 (M and M(1)=C, Si, Ge, Sn, and Pb); and Metal-metal bond dissociation energies, raman and infrared spectra for the series (pi-C5H5)(CO)3M(1)M(2)Me3(M(1)-Cr, Mo, or W; M(2)=Ge or Sn). The compounds investigated are simple derivatives of boron, carbon, and silicon and the other Group IV elements. Increased knowledge of basic thermodynamic parameters for such compounds is important in assessing the suitability of more complex compounds as fuels, structural materials, and inorganic polymers capable of withstanding exposure to high temperatures.
