| Abstract: | Contributions to the Chemistry of Boron. 187. Crystal and Molecular Structure of Dimeric Tris(diethylphosphino) borane The triclinic unit cell of dimeric tris(diethylphosphino) borane, space group P1 , contains two crystallographically independent molecules, both possessing a planar P2B2 ring due to the crystallographic inversion center. The BP bonds of the rings are 0.04 Å shorter than those to the terminal diethylphosphino groups. Both molecules distinguish themselves, although not drastically, by the conformational orientation for the substituents. |
