The synthesis of a series of zinc(II) complexes with Schiff bases products of condensation of 2-tosylamonobenzaldehide with various aminoalcohols containing aliphatic spacers of a variable length (CH2)(n) (n = 2-6) was performed. All compounds were characterized with C, H, N elemental analysis, FT-IR, H-1 NMR, X-ray absorption spectroscopy, UV-Vis and photoluminescence data. The local atomic structures of complexes were determined by X-ray absorption spectroscopy from analysis of EXAFS and XANES of Zn K-edges. The electronic absorption spectra, photoluminescence, and biological activities of the complexes were investigated. The assignments of the experimental UV-Vis spectra of zinc(II) complexes have been carried out by Time-Dependent Density Functional Theory TD-DFT calculations. (C) 2018 Elsevier Ltd.
