In this study, N-(bis(morpholino-4-yl)phosphoryl)-4-methylbenzamide was synthesized, and studied by X-ray crystallography at 293 K. The compound crystallizes in the monoclinic space group P21/n and the asymmetric unit contains one molecule. The crystal parameters are a = 10.6377 (5) Å, b = 9.3419 (5) Å, c = 18.3116 (7) Å, and β = 99.555 (3)° with Z = 4. The NH unit adopts a –sp orientation with respect to the P(O) group, and molecules are assembled as centrosymmetric dimers through two equal NH⋯OP hydrogen bonds, forming an ????22(8) hydrogen-bond ring motif. The C—H···O, H···H, and H···π contacts are observed in the three-dimensional supramolecular structure. To illustrate a comprehensive view of the intermolecular interactions, Hirshfeld surface analysis was employed.
