摘要：

The 55Mn nuclear quadrupole resonance in π-pyrrolenylmanganese tricarbonyl is reported. The temperature-dependent 55Mn nuclear quadrupole resonance of π-pyrrolenylmanganese tricarbonyl and π-cyclopentadienylmanganese tricarbonyl was studied. The data suggest that the π-pyrrolenyl-manganese bond is significantly distorted via a pyrrole slippage such that the manganese to nitrogen and α-carbon bond distances are shorter than the manganese to β-carbon bond distances. The π-pyrrolenyl-manganese bond might be described as a four-electron metal π-heterocyclic allylic and a two-electron metalolefin bond rather than a six-electron α-cyclopentadienyl-type bond. A fast-sweep nqr spectrometer is also described. © 1969, American Chemical Society. All rights reserved.
