Crystal-Structure of Trimethylphosphine Oxide

Abstract

The structure of [P(O)Me₃] has been determined by X-ray diffraction: crystals are monoclinic, space group C2/m with a 10.86(1), b 9.026(6), c 5.394(4) Ǻ, β 92.09(8)° with Z =4. Molecules lie on crystallographic mirror planes; P-O 1.489(6), P-C 1.772(6) and 1.770(10)Ǻ, <O-P-C 112.2(2) and 114.0(4)°, <C-P-C 105.6(3) and 106.2(3)°.
