✦ Synopsis

An X-ray crystallographic study of the Summary: title compound shows it to have an axial Me2N with pyramidal N and a lengthened N-P bond. Conversely, the endocyclic NH-P bond is shortened. The origins of these effects are assigned to specific geometrical relationships of the Me2N/P=S and NH/P=S groupings imposed by the ring system. The dialkylamino group, when attached to phosphoryl phosphorus (P=O), generally displays very nearly trigonal planarity about nitrogen and coplanarity of the P=O and R,N as in I. Typical
