This reaction not only plays a key role in supplying bio-accessible nitrogen to all life forms on Earth, but also embodies the powerful chemistry of cleaving the inert N,N triple bond under ambient conditions. The group of enzymes that carry out this reaction are called nitrogenases and ...
N triple bond stretch IR « on: January 17, 2014, 08:17:14 AM » Im trying to identify a diazo salt presence in some of my samples and different books are giving me different figures for an N triple bond N or even an N double N stretch. Just thought it would be easier to ...
Activation of the N≡N triple bondUtilization of the N≡N bondNitrogen fixationThe activation of the N≡N triple bond requires the coordination of N 2 molecule to transition metal centers. It is predicted that the stronger M-N 2 bond the easier N≡N triple bond utilization, which could ...
The calculations predict very short distances and large bond dissociation energies for the central B−B bonds. The nature of the bonding situation was investigated with an energy decomposition analysis. It shows that the central boron−boron bonds are genuine triple bonds. The π-bonding ...
