Abstract: The title compound, C₃₆H₂₇NOP₂, has been reported as a ligand on rhodium for the catalysis of hydroformylation reactions. The key feature of the compound is the intramolecular PP distance of 4.255 (2) Å. The bond angles at the P atoms range from 99.93 (10) to 103.02 (10)°. The phenoxazine ring system is essentially planar and a non-crystallographic mirror plane through the NO vector bisects the molecule. The C-O bond lengths range from 1.388 (2) to 1.392 (2) Å and the C-N bond lengths range from 1.398 (3) to 1.403 (3) Å.
