摘要：
The crystal structure of Triphenylphosphine Oxide, C18H15PO, was reinvestigated using Mo-Kalpha radiation lambda = 0.71069 angstrom, mu(Mo-Kalpha) = 1.36 cm-1. M(r) = 278.1, orthohombic, Pbca, a = 29.089(3), b = 9.1347(9), c = 11.261(1) angstrom, V = 2992.2 angstrom3, Z = 4, D(x) = 1.235 Mg m-3. The structure was refined by full-matrix least-squares to R = 0.040 and R(w) = 0.036 for 1848 unique reflections and 182 variables. Improved bond lengths and angles were obtained; O-P is 1.479(2) angstrom, weighted means of P-C is 1.803(1) angstrom, O-P-C is 112.6(1)-degrees and C-P-C is 106.2(1)-degrees.
