A series of zirconium (IV) Schiff-base complexes formulated as [Zr (Lx)2] and [Zr (Lx′)2] were synthesized by reaction of tetradentate salicylaldimine Schiff-base ligands with [Zr (acac)4] in methanol

New tetradentate Schiff base ligand (LSB) and its palladium(II) complex, i.e., complexation of N,N'-bis(4-methoxysalicylidene)-2,2-dimethylpropane-1,3-diaminopalladium(II) (PdLSB) has been successfully synthesized through condensation reaction between primary amine 2,2-dimethyl-1,3-propanediamine with 2-hydroxy-4-methoxybenzaldehyde. The palladium complex was then prepared by refluxing the corresponding LSB with an equimolar amount of palladium(II) acetate to give C21H24N2O4Pd. The complex was characterized by using several techniques, such as the elemental chemical analysis CHN, FTIR, NMR spectroscopy and single crystal X-ray crystallography. This air/moisture stable complex was investigated to be a high class of homogeneous catalyst for Mizoroki-Heck reaction. The reaction was monitored by GC-FID at 12 h reaction period. The percentage conversion of 4-bromoacetophenone was 70 % indicated that PdLSB can act as an ideal potential catalyst in the Mizoroki-Heck reaction.

The μ-oxo-bridged Fe(III) dimer complex [{Fe(4-MeOL1)}2(μ-O)]?HOCH3, (H2-4-MeOL1 = N,N′-bis(4-methoxy-2-hydroxybenzylidene)-2,2-dimethylpropane-1,3-diamine), 1 is synthesized and characterized by single crystal X-ray diffraction. Complex 1 contains a [{Fe(4-MeOL1)}2(μ-O)] dimeric unit with a methanol solvent molecule of crystallization. Each Fe(III) ion has a distorted square-pyramidal coordination geometry. In the basal plane, the Fe(III) atom is coordinated by two N and two O atoms of the Schiff base ligand. The apical position is occupied by a bridging O2– ion, linking another Fe(III) ion in the complex. There are intermolecular C–H…O and C–H…π interactions among the dinuclear complexes.
