Puckering behavior in six new phosphoric triamides containing aliphatic six- and seven-membered ring groups and a database survey I datesCheck for up of analogous ring-containing structures
Original language description
The influence of a N heteroatom on the ring conformations of six- and seven-membered aliphatic rings in six new C(O)NHP(O)-based phosphoric triamide structures (analysed by X-ray crystallography) is investigated. Additionally the influence of steric and crystal packing effects is also studied by the analysis of Hirshfeld surfaces. The results are compared to analogous structures with three-to seven-aliphatic membered rings deposited in the Cambridge Structural Database. In the newly determined structures, the six-membered rings only show the near-chair conformation with a maximum deviation of the theta puckering parameter of 4.4 degrees from the ideal chair value of 0 degrees/180 degrees, while the seven-membered rings are found in different conformations such as near-chair, twist chair and twist sofa.
