Description
Summary:In the title compound, C(21)H(18)BrN(2)O(5)P, the six-membered oxaza-phosphinine ring is in a twist-boat conformation. One of the phosphoryl O atoms is in an equatorial configuation while the other is axial with respect to the oxaza-phosphinine ring. The mean planes of the benzene ring to which the nitro group is attached and the phenyl ring form a dihedral angle of 83.5 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains along [100].
