In the title compound, C19H17N2O3P, the six-membered 1,3,2-oxazaphosphorine ring adopts a twist-boat conformation with the phosphoryl O atom in an equatorial position. The P=O(oxide) bond length is 1.457 (1) Å and the average value of the P—O distances is 1.588 Å. The crystal structure is stabilized by C—H⋯O and C—H⋯π interactions.
The title compound, C6H13ClNO+·C6H2N3O7
−, was synthesized from picric acid and 4-(2-chloroethyl)morpholine. The crystal structure is stabilized by C—H⋯O and N—H⋯O hydrogen-bond interactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
