A complex of terbium(Ⅲ) with Schiff base salicylaldehyde-taurine and 1,10-phenanthroline was synthesized. The molecular formula was [Tb (sal-taurine) (1,10-phen) (NO_3)]·2H_2O (sal=salicylaldehyde, 1,10-phen=1,10-phenanthroline). The composition of the title complex was determined by elemental analysis and EDTA volumetic analysis. IR, Molar conductivity and X-ray powder diffraction were performed for its characterizations. The thermal decomposition kinetics of the complex were investigated under non-isothermal condition using the Achar differential method and the Coats-Redfern integral method. The kinetic equation for the second step corresponds to the mechanisms of the Zhuralev, Lesokin and Templman equation were obtained.

Active oxygen species have a carcinogenesis effect, and can cause mutation, cardiovascular diseases, inflammation and aging, etc. Hydroxyl radicals generated either from a radiolysis of water contained in biological tissues or from a redox cycling implicated in a wide range chemical toxicants, have been recognized as the extremely reactive oxidative species which can attack DNA bases and sugar moiety of nucleotides and lead to radiation or chemical injury of DNA and other biological targets[1-5].Therefore, In recent years many pharmacologists and biologists are looking for effective free radical scavengers, especially naturally occurring antioxidants of oxidizing free radicals as drugs.

The binuclear Schiff base complexes prepared by condensation 2,6-diamino-pyridine and salicylaldehyde (LH) by using microwave and adding metal salts to ligand by same ratio. The Schiff base ligand was checked by infrared, electronic spectra and 1HNMR spectroscopy and prepared complexes characterized by molar conductivity, infrared, electronic spectra and susceptibility measurements. The values of molar conductivities reveal that the complexes are non-electrolytes, from obtained data of electronic spectra and magnetic moment, an octahedral geometry was suggested, coordinated to the metal ions in a manner with N donor sites of imine groups, and oxygen of phenolic OH group.

A simple and concise approach for the synthesis of a series of new heterocyclic systems of 2-（benzofuran-2-yl）- benzo[h]quinoline-3-carboxylic acid derivatives （3a--3g） is described. The synthetic strategy features the one-pot reaction of ethyl 2-（chloromethyl）benzo[h]quinoline-3-carboxylate （2） with various substituted salicylaldehydes as well as 2-hydroxy-l-naphthaldehyde as a key step. The substrate 2 was prepared in good yield by a mild, efficient and direct reaction of 1-naphthylamine （1） with Vilsmeier-Haack reagent. The structures of all the new compounds were identified by spectral data and elemental analysis.

A new dinuclear copper(II) complex ([Cu(C12H17N2O)(N3)]2, C24H34Cu2N10O2) has been synthesized and characterized by X-ray structure determination. It crystallizes in the monoclinic system, space group P21/c with a = 18.529(4), b = 10.933(2), c = 14.534(3) ?, β = 111.07(3)°, V = 2748(1) ?3, Z = 4, Mr = 621.69, F(000) = 1288, Dc = 1.503 g/cm3 and μ(MoKα) = 1.590 mm?1. The structure was refined to R = 0.0647 and wR = 0.1846 for 4406 observed reflections (I > 2σ(I)). The asymmetric unit comprises two halfmolecules. The complex is a centrosymmetric dimmer in which the copper atoms are penta-coordinated by three coordination atoms from the corresponding tridentate Schiff base ligand and two bridging azide anions. The Cu(II)…Cu(II) average distance is 3.350(1) ?.

The title complex [Cu3L3(H2O)]DMFH2O (H2L = 4-(3-hydroxy-2-ethyl-4- pyridinone-1-yl)-aniline condensation salicylaldehyde) was obtained. The single-crystal X-ray study shows that it is a trinuclear compound [Cu3(C20H15N2O3)3(H2O)]DMFH2O. The coordi- nation sphere about each copper ion in the complex consists of two oxygen atoms from hydroxylpyridinone moiety of one ligand and one oxygen and one nitrogen atoms from salicyladehyde Schiff-base moiety of another ligand arranged in a slightly distorted square planar geometry. Among the three copper ions, one (Cu(2)) is coordinated by the other oxygen atom of water molecule on the fifth coordinate position to form a distorted square pyramid geometry. The crystal is of monoclinic, space group P21/c with a = 12.9202(5), b = 27.197(1), c = 17.0116(7) ? b = 100.588(1), V = 5875.9(4) 3, Z = 4, C63H57N7O12Cu3, Mr = 1294.78, Dc = 1.464 g/cm3, m = 1.146 mm-1, F(000) = 2668, R = 0.0784 and wR = 0.1546 for 6926 observed reflections with I > 2s(I). The differences of coordinate bond lengths are observed between anhydrous and hydrous units: in the former unit, the average bond lengths are 1.978 ?for CuN (azomethine), 1.883 ?for CuO (phenolic) in Schiff-base moiety, 1.959 ?for CuO (keto), and 1.919 ?for CuO (hydroxy) in hydroxypyridinone moiety; while those in the latter are longer with the following corresponding values: 1.985(5), 1.908(5), 1.993(5) and 1.919(4) ? respectively. The Cu(2)O (water) bond length is 2.375(6) ?
