Typical Ligands That Often Behave As Redox Non-Innocent Ligands
- O2 and NO.
Ligands with extended pi-delocalization such as porphyrins and phthalocyanines, ligands with the generalised formulas 2- or D=CR-CR=D (D = O, S, NR’ and R, R' = alkyl or aryl), and similar related systems are often non-innocent. For example:
- dioxalenes, such as catecholates.
- dithiolenes, such as 1,2-maleonitriledithiolate
- diimines such as derivatives of 1,2-diaminobenzene, α-diimines, and dimethylglyoxime.
- pyridine-2,6-diimine ligands (relevant in polymerisation and hydrogenation catalysis).
The pyridine-2,6-diimine ligand can be easily reduced by one or two electrons.

Famous quotes containing the words typical and/or behave:
“It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a womans adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.”
—Terri Apter (20th century)
“The relationship between mother and professional has not been a partnership in which both work together on behalf of the child, in which the expert helps the mother achieve her own goals for her child. Instead, professionals often behave as if they alone are advocates for the child; as if they are the guardians of the childs needs; as if the mother left to her own devices will surely damage the child and only the professional can rescue him.”
—Elaine Heffner (20th century)
