Abstract
The compound crystallizes in the monoclinic space group P 21/c with four molecules per unit cell, and with the lattice parameters a = 11.807 Å, b = 13.070 Å, c = 11.312 Å, β = 96.74°. With X‐ray diffraction data collected on a four circle diffractometer, the crystal structure has been determined by direct methods and refined to an R‐value of 0.061 for 2735 measured and symmetrically independent reflections. The substance is a derivative of acetales of formyl diphenyl phosphine oxides. Correlations between the geometry of the structure and NMR‐data are of interest.Keywords
