摘要

Starting in 1986 there has been a rekindling of interest in compounds featuringsigma bonding between the heavier group 13 and 15 elements. Much of the motivation for this enhanced interest stems from the fact that some of these compounds can function as single source precursors to compound semiconductors such as gallium arsenide and indium phosphide. The 1:1 stoichiometry compounds of empirical formula R2MER2 have been found to adopt monomeric, dimeric, or trimeric structures. If the substituents on M and/or E are of modest size, trimers are isolated while sterically demanding substituents promote monomer or dimer formation. For the molecules (Me3SiCH2)2AsGa(Cl)R) (R = Me, Ph) the steric situation is such that dimer trimer equilibrium in solution is detectable spectroscopically. We report the first example of the isolation of dimers and trimers of the same empirical composition.
