Abstract

The reactions of N [triple bond, length as m-dash] W(O^tBu)₃ with the low-coordinate phosphorus compounds (Me₃Si)₂NP(NSiMe₃)₂ (I) and (Me₃Si)₂NPS(N^tBu) (II) were studied. Quantum chemical calculations were used to determine why Mo- and W-containing compounds with the same composition have different molecular structures.
