Tetrametallic lanthanide(III) phosphonate cages: synthetic, structural and magnetic studies.

The synthesis, structures and magnetic properties of a family of lanthanide complexes containing phosphonate ligands are reported. Reaction of hydrated lanthanide nitrate and (t)butylphosphonic acid under reflux conditions in iso-butanol, in the presence of pivalic acid as a co-ligand produced five new lanthanide complexes; pyridine (py) was present as a base. The compounds formed are tetrameta...

Reductive deoxygenation of CO2 by a bimetallic titanium bis(pentalene) complex.

The bimetallic bis(pentalene) complex (μ:η(5),η(5)-Pn(†))2Ti2 reductively splits CO2 to form a bis(oxo) bridged dimer [(η(8)-Pn(†))Ti(μ-O)]2, in which the Ti-Ti bond has been cleaved, and the dicarbonyl complex (μ:η(5),η(5)-Pn(†))2[Ti(CO)]2.

Anti-inflammatory and antimicrobial studies of biosensitive Knoevenagel condensate β-ketoanilide Schiff base and its Co(II), Ni(II), Cu(II) and Zn(II) complexes

A new series of transition metal complexes of Co(II), Ni(II), Cu(II) and Zn(II), has beensynthesized from the Knoevenagel condensate Schiff base ligand(L) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. Structural features were determinedby spectral and analytical techniques. Square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

Isolation and characterization of the first circular single-stranded polymetallic lanthanide-containing helicate.

A thorough examination of the disassembly of bimetallic triple-stranded lanthanide helicates [Ln2(Li)3]6+ (stoichiometry S = m/n = 2/3 = 0.67, global complexity GC = m + n = 2 + 3 = 5) in excess of metals shows the competitive formation of standard linear bimetallic complexes [Ln2(Li)2]6+ (S= 1.0, GC = 4), and circular trimetallic single-stranded helicates [Ln3(Li)3]9+ (S= 1.0, GC = 6).
