摘要
The unique structure of [(tBuN)(2)PK](infinity) (2) (containing [(tBuN)(2)P](-) monoanions) is in stark contrast to the previously reported Li+ analogue [{[tBuNP(mu-NtBu)](2)}(2)]Li-4 (1) (containing the dimeric [{tBuNP(mu-NtBu)}(2)](2-) ion). DFT and P-31 NMR spectroscopic studies reveal that the formation of the monoanion arrangements are most thermodyamically favored for Li, Na, and K, 1 being the product of kinetic control and 2 being the product of thermodynamic control.
