Separation nitrogen donor ligands

This method of synthesis of seven-coordinate complexes could have been considered in Section II,C,3, i.e., halogen oxidation of carbonyl complexes containing monodentate nitrogen donor ligands. However, a separate section is given to these [MX2(CO)3(NCMe)2] complexes, as an extensive chemistry has been developed over the 10 years since the details of their synthesis first appeared in 1986." 100...

For ease of systematization, we will regard all chelate diamine "ligands with the two nitrogen donors separated by —(CH2)2— as related to ethylenediamine (en). These generally form five-membered chelate rings and the atoms will be numbered consecutively N(l)—C(2)—C(3)—N(4).
