A trinuclear zinc(II) complex [Zn3L2(μ-O2CCH3)2(H2O)2]H2O2CH3OH (1) was synthesized from an in situ reaction between zinc acetate and a Schiff base ligand (H2L = 2-((2-hydroxyphenylimino) methyl)-6-methoxyphenol). The ligand was prepared by (1:1) condensa

Inspired from biological counter parts, chemical modification of Schiff base derivatives with function groups may provide a highly efficient method to detect amino acids. Therefore, a fluorescent probe involving Schiff base and hydroxyl group has been des
Tetranuclear dysprosium single-molecule magnets: Tunable magnetic interactions and magnetization dynamics through modifying coordination number
Zhang, Kun,Li, Gao-Peng,Montigaud, Vincent,Cador, Olivier,Le Guennic, Boris,Tang, Jinkui,Wang, Yao-Yu
, p. 2135 - 2141 (2019)
The study of mononuclear lanthanide-based systems, where the observed Single Molecule Magnets (SMMs) properties originate from the local magnetic anisotropy of the single lanthanide ion, has been extensively investigated in the literature. The case for po
Hepta-coordinated heteroleptic derivatives of zirconium(IV): Synthesis, structural characterization and ring opening polymerization of ε-caprolactone

, p. 163 - 171 (2016)
A series of new hepta-coordinated heteroleptic derivatives of zirconium(IV) of the types [(CH3COCHCOCH3)2ZrL] (1, 3, 5 and 7) and [(C6H5COCHCOC6H5)2ZrL] (2, 4, 6 and 8) (L?=?a dianionic [ONO]-tridentate ancillary ligand) was synthesized quantitatively by reacting Zr(OPri)4·PriOH with the tridentate Schiff's base ligands H2Lx(H2L1?=?C13H11NO2; H2L2?=?C13H10BrNO2; H2L3?=?C14H13NO3; H2L4?=?C17H13NO2) and β-diketones (acetylacetone/dibenzoylmethane) in a 1:1:2 stoichiometry using dry benzene and ethanol as solvents. All these newly synthesized solid derivatives were fairly soluble in common organic solvents. They were characterized by elemental analyses, FTIR and NMR (1H and13C) spectral studies. Single crystal XRD data of complexes 1, 2, 3 and 5 indicated the hepta-coordination and monomeric nature of these complexes. Furthermore, all these derivatives were tested for the ring opening polymerization of ε-caprolactone. The dibenzoylmethane derivatives were inactive in polymerizing ε-caprolactone unlike the acetylacetonate complexes. The molecular weight and polydispersity index values of polycaprolactone were obtained by GPC analysis. Kinetic studies for the rate of polymerization of ε-caprolactone by these catalytically active zirconium(IV) complexes authenticated the first order dependence of the polymerization rate on the monomer concentration. Among these, complex 3, with an electronegative bromine atom on the Schiff's base moiety, exhibited the best catalytic activity with a conversion of >95% in 2?h.
