examples for each type.

Which metals form dinitrogen complexes? Which other ligands can coexist in a
nitrogen metal complex? Give any two examples of such complexes are prepared by
using nitrogen gas directly. Give suitable chemical equations.

Give an example of a transition metal-dinitrogen complex. Give suitable chemical equation for
its preparation. In what fashion can the two metal atoms be bridged by dinitrogen? What
happens when the dinitrogen ligands bind in side-on mode? Gives suitable diagrams.

 With the help of suitable diagrams, explain the synergic bonding in metal carbonyls

 What are Racah parameters? What do they signify? The gas-phase ion V3+ has a 3F ground
term. The 1D and 3P terms lie, respectively, 10,642 and 12,920 cm-1 above it. The energies of
the terms are given in terms of Racah parameters as E(
3F) = A=8B, E(
3P)=A+7B, E(
1D) =
A-3B+2C. Calculate the values of B and C for V
3+
