A new melt approach has enabled the synthesis of the first catena ‐hexaphosphorus dications, as described in the Communication by N. Burford, J. J. Weigand, and co‐workers on page 6733 ff. The cover picture (by Jared MacPherson) shows a photograph of the reaction melt of 4/5 (PhP) 5 , 2 Ph 2 PCl, and 2 GaCl 3 at 100 °C, which solidifies to yield [P 6 Ph 8 ][GaCl 4 ] 2 quantitatively upon further heating. Such cations represent a new direction in phosphorus chemistry and promise a parallel to catena ‐carbon (organic) chemistry.
