Reactions of BeEt2 with bis­(diphenylphosphinimino)­methanes H2C­[PPh2NR]2 yielded the first bis­(diphenylphosphinimino)­methanide and bis­(diphenylphosphinimino)­methanediide beryllium complexes [CH­(PPh2N-2,6-i-Pr2C6H3)2]­BeEt (1), [C­(PPh2NSiMe3)2]­(BeEt)2 (2), and [C­(PPh2NPh)2]­(BeEt)2 (3), respectively. 13 were characterized by multinuclear NMR and IR spectroscopy as well as single-crystal X-ray diffraction.
