The P atom in the title compound, C19H18NO3P, exhibits a distorted tetrahedral configuration while the N atom shows a planar coordination. In the crystal, intermolecular N—H…O hydrogen bonds form centrosymmetric dimers.

In the title molecule, C18H23ClN3O2P, the P atom is bonded in a distorted tetrahedral environment. The P=O and N—H groups are syn with respect to each other. The angles at the tertiary N atoms confirm their sp2 character. ...

In the title compound, C21H21FN3O2P, the NH and P(=O) groups of the C(=O)NHP(=O) fragment are in a syn arrangement with respect to each other, as are the two amide H atoms of the two CH3–4-C6H4–NH moieties. In the crystal, ...

In the title compound, C14H18N3OP, a crystallographic mirror plane bisects the molecule (the C,N,C atoms of the dimethylamido moiety and the P=O unit lie on the mirror plane). The P atom has a distorted tetrahedral geometry; ...

In the title compound, C15H25FN3O2P, the phosphoryl group is in an anti and syn orientation to the C=O and N—H groups, respectively. The P atom is in a distorted tetrahedral environment. One of the ethyl groups is disordered ...

The P atom in the title molecule, C10H23ClN3O2P, has a distorted tetrahedral coordination. In the C(O)NHP(O) unit, which has syn-oriented phosphoryl and N—H groups, the P—N bond of 1.703 (2) Å is longer and the O—P—N angle ...

The asymmetric C atom in the title compound, C21H17BrClNO, is in a slightly distorted tetrahedral environment and the NH unit adopts a gauche orientation with respect to the CO group. In the crystal, pairs of intermolecular ...

The phosphoryl and carbonyl groups in the title compound, C15H20F2N3O2P, are anti with respect to each other (but the P- and C-groups are separated by another atom) and the P atom is in a tetrahedral coordination environment. ...

The P atom in the title compound, C21H33N4O4P, is in a slightly

distorted tetrahedral coordination environment and the

phosphoryl and carbonyl groups are anti to each other. The

environment of each N ...

The phosphoryl and carbonyl groups in the title compound,

C23H24F2N3O2P, are anti to each other. The P atom is in a

tetrahedral coordination environment and the environment of

each N atom is essentially ...
