Abstract
The title compound is formed as colourless moisture and oxygen sensiti ve crystals by the reaction of [LiCH2PMe2NSiMe3](4) with zinc or cobal t chloride in a toluene suspension in the presence of silicongrease (- OSiMe2-)(n) and n-butyllithium. It is characterized by multinucleus NM R spectroscopy and by crystal structure determinations of two differen t crystal individuals. 1. Space group P (1) over bar, Z = 1, lattice d imensions at -70 degrees C: a = 1272.0, b = 1392.6, c = 1417.6 pm, alp ha = 115.33 degrees, beta = 96.75 degrees, gamma = 106.81 degrees; R = 0.042. 2.
