Abstract

The disproportionation of the complex (Et2N) 3Ti (μ-PCy2) Ni (PPh3) affords the coordinatively unsaturated species Ni (PPh3) 3, 1. This compound crystallizes in the triclinic space group, with a= 18.483 (4) Å, b= 16.203 (3) Å, c= 17.783 (4) Å, α= 105.85 (2)°, β= 117.33 (3)°, γ= 92.33 (3)°, Z= 4, and V= 4464 (2) Å3. Full-matrix least-squares refinement of 1042 variables using 6484 data (Fo2> 3σ F o2) gave R= 0.0441 and Rw= 0.0438. The two ...
