The title complex Ca(L)2(H2O)5 [HL=salicylaldehyde-4-aminobenzene sulfonic acid] was synthesized by the reaction of calcium perchlorate with salicylaldehyde-4-aminobenzene sulfonic acid in the CH3CH2OH/H2O. It was characterized by elemental analysis, IR and X-ray diffraction single crystal structure analysis. The crystal of the title complex [Ca(H2O)5(C13H10NO4S)2] belongs to orthorhombic, space group Pca21 with a=1.162 47(18) nm, b=0.725 91(10) nm, c=3.516 3(3) nm, V=2.967 3(7) nm3, Z=4, Dc=1.528 Mg·m-3, μ=4.22 mm-1, F(000)=1 424, and final R1=0.044 2, wR2=0.098 3. The complex comprises a seven-coordinated calcium(Ⅱ) center, with a O7 distorted pengonal bipyramidal coordination environment.

A new Schiff base derived from tyrosine and salicylidene and its copper(Ⅱ ) complex have been synthesized and characterized by elemental analyses,molar conductances,thermal analyses,infrared spectra,electronic spectra and EPR spectra.The composition of the complex is K[CuL(Ac)]· H2O, where L=H13C16NO4.EPR spectra of the copper(Ⅱ) complex were investigated in various solvents at different temperatures.It is found that the linewidth of four hyperfine lines on solution spectra at room temperature is unequal and changes with mⅠ ,this could be satisfactorily explained by the relaxation effect.The relaxation time and the relaxation rate were calculated.By using spectral parameters from solution spectra at low temperature,the bonding parameters of Cu(Ⅱ ) complex were calculated.The bonding characterization and stability of the complex were disscussed.The results show that the in-plane σ -bond and the in-plane π -bond in the complex all play an important role. 相似文献

吲哚基丁烯酮缩氨基硫脲配合物的合成及生物活性 总被引:4,自引:1,他引:3
缩氨基硫脲类Schiff碱化合物因具有显著的抗菌和抗肿瘤等活性而受到广泛关注,研究发现很多这类化合物与金属离子形成配合物以后,生物活性明显增强。例如,3-乙氧基-2-氧代丁醛双缩氨基硫脲(H2KTs)单独用于治疗大鼠腹水癌瘤没有效果,而H2KTs与铜的配合物则可明显抑制大鼠腹水癌瘤。由于研究这类化合物有重要意义,考虑到吲哚类化合物往往出具有多种生物活性,我们利用拼合原理设计合成了一种带有吲哚基团的缩氨基硫脲Schiff碱配体,并制备了其铜、镍、锌、钴四种边渡金属的配合物,并对配体和配合物的抗菌、抗种瘤活性进行了测试。 相似文献
