“…Some of the results of IR spectra analysis are presented in Table 2. In the IR spectra of caprate of copper the band at 1711 cm -1 disappears, which indicates that C=O group is not present in the analyzed complex [12]. Strong aliphatic C-H stretches are observed at 2930 and 2865 cm -1 .…”

“…The absorptions in the range of 1688-1678 and 1394-1352 cm -1 correspond to the asymmetric and symmetric ѵCOO-frequencies of the metal bound carboxylates. The large difference in ΔѵCOOfrequencies (Δѵ>230 cm -1 ) is indicative of monodentate coordination of both the carboxylate groups [11,12]. The complex of copper shows strong bands in region 3420 and 3450 cm -1 range assignable toѴo-H stretching vibrations of coordinated water molecules [13][14][15].…”

The Copper atom in capric acid copper (II) monomeric complex, having formula of the type [M(HL) 2 L 2 ].nH 2 O(M : Cu(II) n=2), ( HL : capric acid) has been prepared and characterized by physico-chemical studies. The complex has been characterized with the help of elemental analysis, conductance measurements, Electronic spectral (UV-Visible) data suggest that the octahedral environment around the central metal ion. Fourier transform infrared spectrophotometer spectra (IR) confirm the presence of monodentate carboxylate anion (Δν =νasyCOO-νsymCOO-)>230 cm -1 ) in the complex. The thermal behavior of complex was studied by thermogravimetry (DTG), differential thermal analysis (DTA). The final decomposition products namely Cu 2 O.

ε-Poly-L-lysine (ε-PL) is a natural food preservative with high safety to humans and a wide antimicrobial spectra. It was found that ε-PL could form precipitates when it contacted to Cu(II) and Zn(II). Thus in this study, two complexes of ZnCl2 and CuCl2 with ε-poly-L-lysine having molecular weights between 2 and 5 kDa were prepared and characterized by elemental analysis (EA), atom absorption spectrometry (AAS), chlorine assay, etc. The results show that the compositions of two complexes can be expressed as [ NH-(CH2)5-CO ] 2n•(ZnCl2)n•2nH2O and [ NH-(CH2)5-CO ] 2n•(CuCl2)n•2nH2O (n=6-18), respectively. The results of FT-IR reveal that the formation of Zn-N and Cu-N coordination bonds. X-RD patterns indicat that the two complexes are new phases different from the raw ε-PL material. On the basis of TG-DTA curves, the complexes have a coordination reaction. From the results of the bacteriostatic test, ε-PL-Zn(II) and ε-PL-Cu(II) have similar antibacterial activity to ligand ε-PL.

Abstract:The complexes of 2,6-dimethoxybenzoic acid anion with ions of Co(II), Ni(II), and Cu(II) have been synthesized as polycrystalline solids, and characterized by elemental analysis, spectroscopy, magnetic studies, and also by X-ray diffraction and thermogravimetric measurements. The analysed complexes have following colours: pink for Co(II), green for Ni(II), and blue for Cu(II) compounds. The carboxylate group binds as monodentate, and bidentate bridging and chelating ligands. On heating in air to 1173 K the complexes decompose in four, three or two steps. At first, they dehydrate in one or two steps to anhydrous salts, that next decompose to oxides of the respective metals. The solubility of the investigated dimethoxybenzoates in water at 293 K is of the order of 10 -2 mol/dm 3 . Their magnetic moments were determined in the temperature range of 76-303 K. The results reveal the compounds of Co(II) and Ni(II) to be high-spin complexes and that of Cu(II) to form dimer.
