Abstract

Diphenyl[1,3‐benzodithiolyl‐(2)]‐phosphinoxide crystallizes in the monoclinic space group P 2~1~/c with four molecules per unit cell. The lattice parameters are a = 9.600 Å, b = 11.270 Å, c = 16.484 Å; β = 99.72°. With X‐ray diffraction data collected at an automatic four circle diffractometer, the crystal structure has been solved by direct methods and refined to an R‐value of 0.08 for 2690 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.
