Cobalt(III) Complexes with Quadridentate Ligands. XII. Crystal Structure of cis-α-Salicylato(Triethylenetetramine)cobalt(III) Chloride Pentahydrate
Bulletin of the Chemical Society of Japan, 1993Co-Authors: Haruo Sekizaki, Eiko Toyota, Yoshihisa YamamotoAbstract:The structure of the cis-α-salicylato(Triethylenetetramine)cobalt(III) ion was confirmed by an X-ray crystallographic analysis. The conformation of the Triethylenetetramine part of this complex was slightly different from the cis-α-glycinato(Triethylenetetramine)cobalt(III) ion. A comparison of the stability of the this cis-α-salicylato complex with that of the cis-α-glycinato complex on the cation-exchange resin and in water, respectively, are described. The signals of the 1H NMR and 13C NMR spectra were assigned based on the crystal structure.

synthesis structure dna binding cleavage and biological activity of cobalt iii complexes derived from Triethylenetetramine and 1 10 phenanthroline ligands
Inorganica Chimica Acta, 2014Co-Authors: H Gopinathan, N Komathi, M N ArumughamAbstract:Abstract The cobalt (III) complexes, [Co(trien)(phen)] (ClO4)2Cl, (1), [Co(trien)(phen)](NO3)3, (2) (where trien = Triethylenetetramine, phen = 1,10-phenanthroline) has been synthesized and characterized by Infra-red, UV–Vis, ESI-MS and elemental analysis methods. Complex 1 was structurally characterized by single crystal X-ray crystallography. It was crystallized in a triclinic system with space group P 1 ¯ , a = 7.797(10) A, b = 10.6584(2) A, c = 14.889(3) A, α = 96.83(10)°, β = 96.16(10)°, and γ = 98.88(10)°. The cobalt atom assumes a distorted octahedral geometry by coordinating to 6 nitrogen atoms from four Triethylenetetramine and two 1,10-phenanthroline ligands. The binding of this cobalt (III) complex with calf thymus DNA (CT-DNA) was investigated by UV–Vis absorption, fluorescence spectroscopic, cyclic voltammetric and viscosity techniques. Also, the interactions of pBR322 DNA with these cobalt (III) complexes were studied using the gel electrophoresis method. The thermal denaturation and viscosity binding data advocates that the cobalt (III) complexes interact with DNA by groove binding. When compared to complex 2 complex 1 has more potential to the kill human liver cancer cell as revealed by the MTT assay. The cobalt (III) complexes screened for their activities in vitro on common bacteria and fungi and exhibit antimicrobial activities.

Experimental Studies of Reboiler Heat Duty for CO2 Desorption from Triethylenetetramine (TETA) and Triethylenetetramine (TETA) + N-Methyldiethanolamine (MDEA)
Industrial & Engineering Chemistry Research, 2015Co-Authors: Xiao Luo, Zhen Yang, Hongxia Gao, Wichitpan Rongwong, Zhiwu Liang, Paitoon TontiwachwuthikulAbstract:Amine scrubbing is regarded as one of the most suitable technologies for postcombustion CO2 capture. However, data on regeneration energy and performance is limited in literature. In this study, the reboiler heat duties of Triethylenetetramine (TETA) and Triethylenetetramine (TETA) + N-methyldiethanolamine (MDEA) were experimentally evaluated in a bench-scale stripper packed with Dixon ring random packing. The effects of various operating parameters on the desorption performance (presented in terms of reboiler heat duty, Qreboiler) were investigated, including lean loading, rich loading, amine concentration, solvent flow rate, and amine type. The experimental results showed that the Qreboiler was very sensitive to these process parameters. In addition, a comparison of the Qreboiler of TETA, monoethanolamine (MEA), and diethylenetriamine (DETA) was conducted to evaluate the potential for TETA’s application in the CO2 capture process. The results obtained in this work showed that the Qreboiler of TETA, as a...
