Neutral metallamacrocycles with four or ten metal centers were obtained by reaction of [(R3P)PdCl2]2 with 2,3-dihydroxypyridine and derivatives or 2-hydroxynicotinic acid in the presence of base. In all these assemblies, the two O-donor atoms of the ligand ...
Mononuclear trivalent lanthanide complexes with formula [Ln(L)(NO3)3] [in which L=4,4-difluoro-8-(2:2;6:2-terpyridin-4-yl)-1,3,5,7-tetramethyl-2,6-diethyl-4-bora-3a,4a-diaza-s-indacene (Boditerpy)] are reported for Ln=Yb, Nd, Er, La and Gd. According to th ...
New polydentate ligands (e.g., Tsox and TsoxMe) have been synthesized to take advantage of the chelating effect of bidentate 8-hydroxyquinolinate subunits connected to a N,N,N¢,N¢-tetraaminopropyl-1,2-ethylenediamine framework and with the aim of sensitizi ...
The tetradentate chelate ligand tris[(1-vinylimidazol-2-yl)methyl]amine (10) was synthesized in five steps from commercially available starting materials. Upon reaction with MCl2 (M = Zn, Cu, Ni, Co) in the presence of NH4PF6, the complexes [M(10)Cl]PF6 (M ...
A rational approach to the formation of pure heteropolymetallic lanthanide complexes that uses a two-step assembly strategy and exploits the different size requirements of the two metals included in the final structure is described. The investigation of th ...
The synthesis and characterization of a series of cobalt(III) complexes of the general type Co(N2O2)(L-2) are described. The N2O2 Schiff base ligands used are Me-salpn (H2Me-salpn = N,N'-bis(methylsalicylidene)-1,3-propylenediamine) (1-3) and Me-salbn ...
The diastereoselective synthesis of chiral coordination compounds with d metals proved the effectiveness of the pinene-bipyridine approach in predetermining the chirality at the metal centre. The strong Lewis acidic character of lanthanide cations required ...
The labile cobalt (II) complex [Co(TUF)2(Pic)2] with 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (TUF) bidentate and 4-methylpyridine (Pic) monodentate ligands was studied by variable temp. (VT) 19F NMR from 184 to 312 K. In contrast to the solid state, ...
A series of coordination polymers contg. Group I or II metal ions, connected via an imidazolium-centered dicarboxylate ligand, have been isolated from water and characterized by single crystal X-ray diffraction. All the structures incorporate water mols. t ...
With a view to develop drugs that could resist hydrolysis in aq. media,organometallic arene-capped ruthenium(II) 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (RAPTA) complexes bearing chelating carboxylate ligands have been prepd. and studied. The new com ...
