Multiple Bonding Between Heavier Group 13 Elements,. In spite of the fact that only about a dozen such compounds have been isolated under ambient conditions, the area has generated widespread debate owing to widely differing opinions on the multiplicity of the bonding in some compounds, especially the ‘gallyne’ Na.Ga.(C.H.-2,6-Trip.).
