Crystal structure of 10-phenylphenoxaphosphine
Abstract
The molecular structure of 10-phenylphenoxaphosphine has been determined by X-ray diffraction (heavy-atom) methods. The unit cell is monoclinic, a= 8.47(1), b= 9.48(1), c= 19.83(1)Å, γ= 118.85(2)°, space group P21/a, Z= 4. Diffractometer data were refined to R 0.054 for 2 159 observed reflections. The phenoxaphosphine residue is folded about a line almost passing through the oxygen and phosphorus atoms, and the geometry at the phosphorus atom is nonplanar.
