3-(6-Methyl-2-pyridyl)-2-phenyl-3,4-dihydro-1,3,2-benzoxazaphosphinine 2-oxide
In the title compound, C(19)H(17)N(2)O(2)P, the six-membered 1,3,2-oxazaphosphinine ring adopts a boat conformation with the phosphoryl O atom in an equatorial position. The dihedral angle between the 6-methyl-2-pyridyl and phenyl groups is 75.5 (1)°. These substituents are trans to each other, and...

Sumario: | In the title compound, C(19)H(17)N(2)O(2)P, the six-membered 1,3,2-oxazaphosphinine ring adopts a boat conformation with the phosphoryl O atom in an equatorial position. The dihedral angle between the 6-methyl-2-pyridyl and phenyl groups is 75.5 (1)°. These substituents are trans to each other, and are oriented at angles of 57.2 (1) and 74.8 (1)°, respectively, to the benzene ring. The crystal structure is stabilized by intra- and intermolecular hydrogen bonds. The phosphoryl O atom participates in intermolecular C—H⋯O interactions with the neighbouring molecules, forming centrosymmetric R (2) (2)(14) dimers. |
