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 ...
4 pm (observed for the first time in the case of Nb) is explained in terms of a triple bond. This Nb//2 dumbbell is coordinated fourfold 'side-on' by the Nb**4 ** plus ions.doi:10.1002/anie.198609961Jürgen KhlerArndt Simon
NO+ 它有3个bonds 可是这样的话 氧就要变成正1 (+1)可是 N 不是比氧正吗因为我上的是英文所以也不知道中文怎么说如果看得懂我写的并知道原因的请帮我看看Which of the following molecules or ions contain a triple bond?(a) N2(b) HCCCl(c) O2 2–(d) CO(e) NO+The answers are:A,B,D...

The shifting towards the lower wavenumber is due to the additional interaction that decreases the electron density of CN triple bond, which is consistent with the multiple interactive nature of [N(CN)2]−. The anion [N(CN)2]− likely forms an adduct with PbI2•DMSO•MAI (see the ...

The signal at 2200 cm−1 is ascribable to the CN triple bond stretching [46], the main band around 1600 cm−1 is assigned to overlapping signals from C = C and C = N stretching vibrations [44,46], while the shoulder at 1710 cm−1 is associated with the stretching of C = O...
