The cover of Angew. Chem. Int. Ed., 2013, V.52, Issue 41: Stabilization of Tetrahedral P4 and As4 Molecules
A new chapter in the history of arsenic has been opened up by M. Scheer et. al. in their Communication. Long after the discovery of grey and yellow arsenic by Albertus Magnus and Anton Bettendorff, the structure of As4 has finally been described by X-ray crystallographic techniques. Highly reactive yellow arsenic was embedded in a polymeric matrix, which minimizes molecular motion and therefore allows the determination of the As–As bond length.
