A new Schiff base ligand, salicylaldehyde-4, 4'-diaminodiphenyl ether (L), and its complexes with Mg (II) have been synthesized. The Mg (II) complex was characterized by elemental analysis and infrared spectrum. The results indicate that the Mg (II) ion coordinates to the nitrogen atoms and oxygen atoms of the ligand. The fluorescence properties of Mg (II) complex material in solid and in organic solvents were studied. The solvent factors influencing the fluorescent intensity are discussed.

A new luminescent materials, 1-acetyl-2-naphthol-4, 4’-diaminodiphenylsulfone Cd (II) has been prepared by the reaction of 1-acetyb-2-naphthol-4, 4’-diaminodiphenylsulfone (L) with cadmium nitrate in methanol-water (v:v=5:1)solution. The infrared spectrum and luminescent properties of Cd (II) complex material are investigated. The results indicate that the fluorescence is in the blue region, and the fluorescence was enhanced after adding the organic solvent DMSO to the Cd (II) complex material.

Complex Material

A mono-ligand neutral Mg (II) complex of a Schiff base ligand derived from 1-acetyl-2-naphthol and 4, 4’-diaminodiphenylmethane was prepared and characterized. The Schiff base acts as a double, negatively charged quadridentate ligand forming stable neutral Mg (II) complex. The luminescent characterizations of the Mg (II) complex material in solid and in organic solvents show that the Mg (II) complex has strong luminescent emission at ca. 452 nm when excited at 323 nm. The Mg (II) complex synthesized may be an excellent luminescent material.

By reactions of indium chloride tetrahydrate with three bis-Schiff bases ligands (N, N’-bis (3-methoxy-salicylidene)benzidine = L1; N, N’-bis (3-methoxysalicylidene)-2, 2’-dimethyl- benzidine =L2; N, N’-bis (3-methoxysalicylidene)-o- dianisidine = L3), respectively, three novel corresponding complexes 1~3 were obtained. The complexes were characterized by infrared spectrum, molar conductance, elemental analysis and thermal gravimetric analysis. The chemical formulae of the complexes 1~3 were determined as (InCl3)2Ln (1, n = 1; 2, n = 2; 3, n = 3). All the complexes are constructed with binuclear indium ions. Every complex consists of two central In (III) ions, one corresponding bis-Schiff base ligand and six Cl-.

The New Schiff base ligand 4,4'-[(1,1'-Biphenyl)-4,4'-diyl,bis-(azo)-bis-[2-Salicylidene thiosemicarbazide](HL)(BASTSC)and its complexes with Co(II), Ni(II), and Cu(II) were prepared and characterized by elemental analysis, electronic, FTIR, magnetic susceptibility measurements. The analytical and spectral data showed, the stiochiometry of the complexes to be 1:1 (metal: ligand). FTIR spectral data showed that the ligand behaves as dibasic hexadentate molecule with (N, S, O) donor sequence towards metal ions. The octahedral geometry for Co(II), Ni(II), and Cu(II) complexes and non electrolyte behavior was suggested according to the analysis data.

AbstractSynthesis and structural characterization of two heterodinuclear ZnII-LnIII complexes with the formula [ZnLn(HL)(µ-OAc)(NO3)2(H2O)x(MeOH)1-x]NO3 · n H2O · n MeOH [Ln = Pr (1), Nd (2)] and the crystal and molecular structure of [ZnNd(HL)(µ-OAc)(NO3)2(H2O)] [ZnNd(HL)(OAc)(NO3)2(H2O)](NO3)2 · n H2O · n MeOH (3) are reported. The asymmetrical compartmental ligand (E)-2-(1-(2-((2-hydroxy-3-methoxybenzylidene)amino)-ethyl)imidazolidin-2-yl)-6-methoxyphenol (H2L) is formed from N1,N3-bis(3-methoxysalicylidene)diethylenetriamine (H2valdien) through intramolecular aminal formation, resulting in a peripheral imidazoline ring. The structures of 1–3 were revealed by X-ray crystallography. The smaller ZnII ion occupies the inner N2O2 compartment of the ligand, whereas the larger and more oxophilic LnIII ions are found in the outer O2O2’ site. Graphic Abstract Synthesis and structural characterization of two heterodinuclear ZnII-LnIII complexes (Ln = Pr, Nd) bearing an asymmetrical compartmental ligand formed in situ from N1,N3-bis(3-methoxysalicylidene)diethylenetriamine (H2valdien) through intramolecular aminal formation are reported.

The reaction of PcMCl 2 ( M = Zr , Hf ) with β-diketones is reported. 1 H NMR and elemental analysis suggest the substitution of two Cl atoms for two β-diketone fragments takes place as a result of this reaction and the complexes PcM(β-dik)2 are formed. All obtained complexes are stable and highly soluble in most organic solvents. The data from 1 H and 19 F NMR, and UV-vis spectroscopy suggest the coordination of two β-diketone ligands in a cis geometry about the central atom of the macrocycle. It was shown bis(β-diketonato)zirconium(IV) and hafnium(IV) phthalocyanines containing β-diketones with donor or acceptor groups or with bulky substituents can be obtained.
