Abstract
The crystal structure of the title compound, C42H40O2P2, an open-chain diphosphine, is reported. The absolute structure determined by the Flack method [Flack (1983). Acta Cryst. A39, 876-881] confirms that the stereochemistry at the chiral centers is (2R,3R). The dihedral angles between the two rings bonded to each phosphine group are 70.94 (10) and 70.20 (10)°, and the angle between the rings of the benzyloxy groups is 59.31 (13)°.
