Abstract

Reaction of an excess of trimethylaluminum with bis(diphenylphosphino)-methane in heptane affords the crystalline complex [A1(CH3)3]2[(C6H5)2PCH2P(C6H5)2]. The title compound crystallizes in the triclinic space group P¯1 with unit cell parametersa=10.053(6),b=11.017(6),c=15.908(8) Å,α=85.58(4),β=71.80(4), γ=77.49(4)°,V=1634(1) Å3, andD c=1.07 g cm−3 forZ=2. Least-squares refinement based on 2924 observed reflection with intensitiesI≥3σI) in the range 2.00≤2θ≤45.0° converged atR=0.050 (R w=0.067). The Al-P distances are 2.585(2) and 2.521(2) Å, and the P-C-P angle is 121.4(2)°.
