Abstract

Crystal structures have been determined for trimethylboron and for a new polymorph of trimethylgallium; in addition, the crystal structure of trimethylthallium has been redetermined. The energy differences between the BMe3-like layered structure and the InMe3-like pseudo- tetrameric structure are calculated using solid state DFT calculations to be-1.7,+ 3.6, and+ 10.4 kJ mol-1 for BMe3, GaMe3, and InMe3, respectively.
