title: Substitutional disorder in the substituted nixantphos ligand C(39)H(32)Br(0.27)Cl(0.73)NOP(2).
abstract: The structure of 10-(3-bromo/chloro-prop-yl)-4,6-bis-(diphenyl-phosphino)-10H-phenoxazine, C(39)H(32)Br(0.27)Cl(0.73)NOP(2), shows chloro/bromo substitutional disorder in a 3:1 ratio. For application as a ligand in catalysis, the intra-molecular P⋯P distance of 4.263 (2) Å is relevant. The phenoxazine ring system is essentially planar.
