Abstract

The crystal structure of Triphenylphosphine Oxide, C18H15PO, was reinvestigated using Mo- radiation λ=0.71069 Å,μ(Mo-)=1.36 cm−1.Mr=278.1, orthohombic,Pbca,a=29.089(3),b=9.1347(9),c=11.261(1) Å,V=2992.2 Å3,Z=4,Dx=1.235 Mg m−3. The structure was refined by full-matrix least-squares toR=0.040 andRw=0.036 for 1848 unique reflections and 182 variables. Improved bond lengths and angles were obtained; O-P is 1.479(2) Å, weighted means of P-C is 1.803(1) Å, O-P-C is 112.6(1)° and C-P-C is 106.2(1)°.
