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 ...

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 ...
