There is a controversy over which group of scientists actually discovered the gamma-phase of elemental boron.
The first synthesis of this phase was probably performed by Wentorf in 1965,Template:Cn but the possibility of chemical contamination was not ruled out and no structure solution was given.
The gamma phase was synthesized again in 2004 by J. Chen and V.L. Solozhenko, who proved that they are dealing with a pure boron phase. The structure was solved by A.R. Oganov in 2006. Oganov, Chen, and Solozhenko published their findings in Nature in January 2009.[1]
At the same time, another group consisting of Dubrovinsky, Dubrovinskaia, and Filinchuk published a paper claiming novelty.[2]
