The synthesis and structure characterization of 2-propyl-5-phenyl-1,4-dioxo-1,2,3,4,5, 6,7,8-octahydro-[1,4,2]diazaphosphorino[1,2-a][1,3,2]benzodiazaphosphorine 3-oxide are described. The title compound has been designed to incorporate proximate carbonyl and phosphoryl groups in a heterocycle fused to benzophosphadiamide heterocycle. Crystal data: C19H20N3O3P, Monoclinic, space group P2(1)/c, with a = 9.7585(9) A, b = 21.4319(19) A, c= 17.7900(16) A, β = 100.823(2)°, Z = 8, V = 3654.5(6) A3. The crystal structure shows that the proximate carbonyl and phosphoryl groups are not coplanar, and the [1,4,2]diazaphosphorino moiety prefers the boat conformation.
