Abstract
The crystal structure of the title compound, C42H40O2P2, an open-chain diphosphine, is reported. The absolute structure determined by the Fl ack 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)degrees, and the angle between the rings of the benzyloxy gr oups is 59.31(13)degrees.
