Small flashes (b) occur during the freezing of triethylgallium samples in liquid nitrogen, and on warming from −196°C this is accompanied by decomposition (a). This effect was observed during the determination of the crystal structures of GaMe 3 and GaEt 3 , which both show intermolecular interactions between their electron‐deficient gallium atoms and the alkyl groups of neighboring molecules.
