The asymmetric unit of the title compound, C(36)H(26)OP(2), comprises two mol-ecules which have slightly different conformations of the phenyl ring substituents. In both mol-ecules, the dibenzofuran unit is close to being planar, with dihedral angles of 3.20 (3) and 1.86 (2)° for the two mol-ecules. Its planarity affects the intra-molecular distances between P atoms, with P⋯P distances of 5.574 (2) and 5.485 (2) Å for the two mol-ecules.
标题化合物C(36)H(26)OP(2)的不对称单元包含两个分子，其苯环取代基的构象略有不同。在两个分子中，二苯并呋喃单元几乎呈平面状，两个分子的二面角分别为3.20 (3)°和1.86 (2)°。其平面性影响了P原子之间的分子内距离，两个分子的P⋯P距离分别为5.574 (2) Å和5.485 (2) Å。
