M r = 218.9, monoclinic, P 2 1 /c, a = 6.870(1), b = 10.824(2), c = 11.337(2) Å, β = = 94.59(2) 0 , Z = 4, V = 840.5(3) Å 3 , D x = 1.73 Mgm −3 . Final R = 0.033 for 2648 independent reflections, excluding those with | F 0 | < 3σ( F 0 ). Intensities were measured with an automatic diffractometer. This organophosphorous compound is characterized by two PC bonds. Four symmetrically independent intermolecular hydrogen bonds determine the threedimensional packing of the molecules and the unique chemical properties of the campound.
