Gregory H. Robinson FRSC is an American synthetic inorganic chemist and a Foundation Distinguished Professor of Chemistry at the University of Georgia.

[1] Robinson's research focuses on unusual bonding motifs and low oxidation state chemistry of molecules containing main group elements such as boron, gallium, germanium, phosphorus, magnesium, and silicon.

Robinson discovered that the main group metal gallium, if properly constrained, could exhibit aromatic behavior.

[5] Robinson's group prepared a compound that contained a three-membered ring of gallium atoms in a dianion, [R3Ga3]2- (R = large organic ligand).

Robinson utilized a similar technique to prepare a highly unusual compound containing a silicon-silicon double bond, with both silicon atoms residing in the formal oxidation state of zero, L:Si=Si:L. Essentially, this compound represented a means to stabilize the highly reactive diatomic allotropes of silicon at room temperature.
