The gamma boron discovery controversy relates to a dispute as to which group of scientists discovered the gamma-phase of elemental boron.
Now, with a hindsight[1], it appears that the first report of this phase was made by Wentorf in 1965[2], but the possibility of chemical contamination was not ruled out and no structural solution was given. In spite of the indirect evidence given by Wentorf, the common opinion was that he synthesized some boron compound and/or a mixture of phases (the latter seems to be correct - it appears he dealt with a mixture of phases containing gamma-B). For these reasons Wentorf's paper had attracted little attention and citation, and most likely for the same reasons Wentorf's data were deleted from the Powder Diffraction Files database.
The gamma phase was synthesized again in 2004 by J. Chen and V.L. Solozhenko, who proved that they were 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.[3]
At the same time, another group consisting of Dubrovinsky, Dubrovinskaia, and Filinchuk published a paper claiming novelty [1]. Oganov and his colleagues maintain that Filinchuk had a copy of Oganov's manuscript since 9 December 2006 but refused to acknowledge this fact.[4]
