 Title    Synthesen und Kristallstrukturen der Lithiumphosphide { Li(DME)[P(f-Bu)2]} 2 und [Li(DM E)PPh2l00 Syntheses and Crystal Structures of the Lithium Phosphides {Li(DME)[P(/-Bu)2]}2 and [Li(DM E)PPh2]0 0  
 Abstract    The title com pounds have been prepared by the reaction o f rc-butyllithium with the corre­ sponding diorganophosphanes H PR 2 (R = r-Bu, Ph) in D M E solutions. Both compounds were characterized by crystal structure determinations. {Li(DM E)[P(f-Bu)2]}2: Space group P 1, Z = 1, 2027 observed unique reflections, R = 0.055. Lattice dimensions at —80 °C: a = 879.9(3), b = 986.3(1), c = 1064.0(2) pm, a = 70.69(1)°, ß = 70.63(2)°, y -69.89(2)°. The com pound forms centrosymmetric dimers o f symmetry Q with L i-P bond lengths o f 260.0 and 257.3 pm for the Li2P2 four-membered ring. [Li(DM E)PPh2]0C : Space group P 2 ,/«, Z = 4. 3437 observed unique reflections, R = 0.055. Lattice dimensions at -8 0 °C: a = 1034.8(2), b = 812.48(9), c = 1978.4(3) pm, ß = 103.30(2)°. The com pound forms polymeric chains via LiP bridges with L i-P bond lengths o f 256.3 and 254.1 pm.
