Another type of tri-imine complexes containing terpyridyl type ligands, in which the inner pyridyl ring has been replaced by an amino moiety, such as di-(2-pyridylmethyl)-amine (dpma) and di-(2-pyridylmethyl)methylamine (medpma) has been described... 

As a tridentate conjugated ligand this would be expected, like 2,2 -bipyridyl and 1,10-phenanth-roline, to stabilize osmium(II) and this is indeed the case, with most of the reported complexes containing divalent osmium. The unsubstituted bis complex [Os(terpy)2]2+ is remarkably stable. It seems likely that terpyridyl complexes of osmium(II) are good candidates for further investigation as photosensitizers, having so far received less attention than the corresponding bipyridyl or phenanthroline species. 

Tridentate N-donor ligands are efficient in separating actinides from lanthanides selectively by solvent extraction, an area of potential great importance in treatment of used nuclear fuel rods. The tridentate ligand 2,2 6 ,2 -terpyridyl (terpy) forms a range of complexes. The perchlorate complexes [Ln(terpy)3] ( 104)3 contain nine-coordinate cations with near- )3 symmetry, a structure initially deduced from the fluorescence spectrum of the europium compound (Section 5.4) and subsequently confirmed by X-ray diffraction smdies (Figure 4.7)... 

Reduction of [V(bipy)3]l2 with the metals Mg or Zn yields the complex [V(bipy)3], which will undergo ftulher reduction by lithium aluminum hydride to Li[V(bipy)3] 4THF, which formally contains V". Similarly, reduction of [V(phen)3] with dUithium naphthalenide or dihthium benzophenone in THF yields [V(phen)3]l2. Further reduction with dilithium benzophenone gives the V complex Li[V(phen)3] 3.5THF. The terpyridyl complex [V(terpy)2] can be obtained as black crystals by reduction of DMF solutions of [V(terpy)2]l2 with Mg or LiAlH. Such low oxidation state complexes are highly air sensitive and decompose if heated to 100 - 200 °C in a vacuum. In these systems, the ligands may have an anion radical character. ...
