Sheikhshoaie, Iran ; Ebrahimipour, S. Yousef ; Crochet, Aurélien ; Fromm, Katharina M.

In: Research on Chemical Intermediates, 2015, vol. 41, no. 4, p. 1881–1891

Reaction of 4-bromo-2-(((5-chloro-2-hydroxyphenyl) imino)methyl)phenol (H₂L) with VOSO₄·XH₂O generates the oxido-vanadium(V) complex [VOL(OCH₃)(OHCH₃)], that characterized by FT-IR, UV–Vis, and elemental analysis. The complex was also characterized by single crystal X-ray diffraction crystallography. A DFT calculation was carried out on the complex using the B3LYP/6-31+G(d,p) method....

A new mixed-ligand copper(II) complex of (E)-N′-(2-hydroxybenzylidene) acetohydrazide: Synthesis, characterization, NLO behavior, DFT calculation and biological activities

Ebrahimipour, S. Yousef ; Sheikhshoaie, Iran ; Crochet, Aurelien ; Khaleghi, Moj ; Fromm, Katharina M.

In: Journal of Molecular Structure, 2014, vol. 1072, p. 267–276

A tridentate hydrazone Schiff base ligand, (E)-N′-(2-hydroxybenzylidene)acetohydrazide [HL], and its mixed-ligand Cu(II) complex [CuL(phen)], have been synthesized and characterized by elemental analyses, FT-IR, molar conductivity, UV–Vis spectroscopy. The structure of the complex has been determined by X-ray diffraction. This complex has square pyramidal geometry and the positions around...
