Gas phase structure of 2,2-dimethylpropylidynephosphine, (CH3)3C-C≡P (Molecular structures of phosphorus compounds ; 9)

Abstract

The geometric structure of 2,2-dimethylpropylidynephosphine, (CH3)3C-C≡P, in the gas phase has been determined by joint analysis of electron diffraction and microwave spectroscopy data. The following parameters (rav values) were obtained: P≡C1 = 1.536(2), C1-C2 = 1.473(4),C2-C3(methyl) = 1.543(2), C3-H = 1.080(3) A,C1-C2-C3 = 109.0(2) and H-C3H = 108.8(5)". Error limits are 2σ values.
