1,2-Bis(phenylphosphoryl)ethane
The geometric parameters of the molecule of the title compound, C14H16O2P2, are in the usual ranges. It is a meso compound with the two chiral P atoms having opposite configurations. The P-CH2-CH2-P chain adopts a trans conformation [torsion angle -178.59 (17)°]. The P=O bonds are almost coplanar with the adjacent phenyl ring [torsion angles = 3.8 (3) and 0.3 (3)°]. Whereas one of them is synclinal [torsion angle = -59.0 (2)°] to the central C-C bond, the other is anticlinal [torsion angle = 56.6 (2)°] to the central C-C bond. The dihedral angle between the two phenyl rings is 5.2 (3)°. The molecules are linked by weak C-H...O hydrogen bonds. They crystallize in rows running along the c axis. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.005 Å; R factor = 0.038; wR factor = 0.093; data-to-parameter ratio = 15.2.
