In the title compound, C16H17Cl3N3O2P, the P—N bonds in the P(O)[NH(2—CH3)C6H4]2 unit [1.623 (4) and 1.637 (3) Å] are shorter than the P—N bond in the C(O)NHP(O) fragment [1.704 (3) Å]. The phosphoryl and carbonyl groups ...

In the title molecule, C17H23N2O2P, the P atom has a distorted tetrahedral environment. The P—N bond to the tolylamido fragment is 1.642 (4) Å while that to the butylamido fragment is 1.629 (3) Å. The dihedral angle between ...

In the anion of the title salt, C7H16N+.C21H35N3O3PS-, the P and S atoms are both in distorted tetrahedral environments and the angles at the tertiary N atoms confirm their sp2 character. The two S=O groups are in syn and ...
