Chloro(2,2':6',2"-terpyridine) platinum, a bulky, hydrophilic reagent, inhibited the renal sodium pump with a single exponential time course. K(+) increased the rate constant of the reaction by about twofold; the K(+) concentration dependence was monotonic, with a half-maximal effect observed at 1 mM, consistent with K(+) acting at a transport site. Na(+), Mg(2+), eosin, and vanadate did not si...

The ability of the terpyridine ligand to stabilize alkyl complexes of nickel has been central in obtaining a fundamental understanding of the key processes involved in alkyl-alkyl cross-coupling reactions. Here, mechanistic studies using isotopically labeled (TMEDA)NiMe(2) (TMEDA = N,N,N',N'-tetramethylethylenediamine) have shown that an important catalyst in alkyl-alkyl cross-coupling reaction...

The title compound, C25H24N3O3P, was obtained by catalytic phospho-nation of 4'-(4-bromphen-yl)-2,2':6',2''-terpyridine. The terpyridine moiety is nearly planar, the dihedral angles between the central and the outer rings being 4.06 (9) and 5.39 (9)°. The N atoms in the two pyridine rings are oriented nearly anti-periplanar to that of the central ring. The benzene ring is rotated out of the pla...

The ethynyl-phenylene substituted 2,2':6',2''-terpyridine (tpy) derivatives, 4-(phenyl-ethynyl)-2,2':6',2''-terpyridine (L(1)), 4-(methoxyphenyl-ethynyl)-2,2':6',2''-terpyridine (L(2)), 4-(tolyl-ethynyl)-2,2':6',2''-terpyridine (L(3)) and 4-(nitrophenyl-ethynyl)-2,2':6',2''-terpyridine (L(4)) have been used to synthesize four new [RuCl(2,2'-bipyridine)(L(n))]PF6 based complexes. Electronic abso...

Platinum(II) complexes bearing various alkyne-pyrene, alkyne-4'-terpyridine and alkyne-dibutoxyphenylacetylide-terpyridine units were constructed in a step-by-step procedure based on copper-promoted cross-coupling reactions with preconstructed modules; formation of bis(ligand) complexes of Fe(II) and Zn(II) by binding of the pendent terpyridine units provided heterotrinuclear derivatives, all o...

A novel series of ruthenium terpyridine complexes with bichromophoric units separated by more than 1 nm display an extraordinary enhancement of their luminescence lifetimes when compared to the parent Ru(tpy)2(2+) chromophore (tpy = 2,2':6',2"-terpyridine).

A study of the molecular magnetism hydrated salts [Ln(H2O)6Cl2]Cl (Ln = Gd (1Gd), Dy (1Dy), Er (1Er), Yb (1Yb)) and lanthanide chloride complexes with 2,2′;6′,2″-terpyridine (terpy) synthesized on their basis, [Ln(H2O)4(terpy)Cl]Cl2·3H2O (2Gd), (2Dy), (2Er), (2Yb), was carried out. It found that both initial chlorides containing Dy, Er, Yb, derivatives terpyridine exhibit properties single-mole...

Three copper(ii) coordination compounds have been prepared from three different 2,2':6',2''-terpyridine-based ligands, which have been selected to investigate the potential role of supramolecular interactions on the DNA-interacting and cytotoxicity properties of the corresponding metal complexes. Hence, the ligands 4'-((naphthalen-2-yl)methoxy)-2,2':6',2''-terpyridine () and 4'-((1H-benzo[d]imi...

A series of mono- and dinuclear alkynylplatinum(II) terpyridine complexes containing the hydrophilic oligo(para-phenylene ethynylene) with two 3,6,9-trioxadec-1-yloxy chains was designed and synthesized. The mononuclear alkynylplatinum(II) terpyridine complex was found to display a very strong tendency toward the formation of supramolecular structures. Interestingly, additional end-capping with...

The use of divergent 4,2?:6?,4?- and 3,2?:6?,3?-terpyridine ligands as linkers and/or nodes in extended coordination assemblies has gained popularity over the last decade. However, there is also a range polymers which feature 2,2?:6?,2?-terpyridine metal-binding domains. Of remaining 45 isomers terpyridine, few have been utilized arrays. Here, we provide an overview networks containing terpyrid...
