Abstract
The synthesis, vibrational spectra, and X-ray diffraction analysis results for 2-(diphenylphosphinylmethoxy) aniline, 2-[(C6H5)2P(O)OCH2]C6H4NH2(I), are described. The crystals are monoclinic: a = 18.4515(17) A, b = 10.5421(12) A, c = 17.897(2) A, β = 104.479(8)°, V = 3370.7(6) A3, Z = 8, space group P21/c, R = 0.0546 for 1770 reflections with I > 2σ(I). The unit cell contains two crystallographically independent molecules Ia and Ib joined by an N-H …O hydrogen bond between a hydrogen atom of the amino group of aniline in molecule Ia (Ib) and the phosphoryl oxygen atom of molecule Ib (Ia) (O…H 2.18 and 2.19 A, N…O, 2.979(5) and 3.000(5) A; NHO angle, 154° and 157°).
