Synthesis and characterization of a novel series of metallothiocarbohydrazone polymers and their adducts

Abstract

A novel linear

Preparation, spectral characterization and antimicrobial activity of binary and ternary Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Ce(III) and UO2(VI) complexes of a thiocarbohydrazone ligand

“…2 E g transition in octahedral complexes [43]. The magnetic moment values of the complexes are in the range 1.47-1.78 B.M., which is consistent with the presence of one unpaired electron [49,50]. The room temperature solidstate ESR spectrum of the copper(II) complex (10), Fig.…”

Synthesis, spectroscopic, biological, and theoretical studies of new complexes from (E)‐3‐(2‐(5, 6‐ diphenyl‐1,2,4‐ triazin‐3‐ yl)hydrazono)butan‐2‐ one oxime

“…[36,[54][55][56] The effective magnetic moment value of the synthesized Cu (II) complex 2 is 1.48 B.M, indicating that Cu (I) ion is oxidized by the monoxime ligand and the existence of one unpaired electron in a square-planar geometry. [57][58][59] It is known that oxime ligands are good oxidizing agents, where the stabilizing influence of the oximic ligand on the high oxidation states of metals is thought to be due to the very strong electron-donating capacity of the deprotonated oxime group. [60] The lower magnetic moment value than expected may be due to the antiferromagnetic interaction of copper with neighboring copper ions.…”

New less toxic zeolite‐encapsulated Cu(II) complex nanomaterial for dual applications in biomedical field and wastewater remediation

“…[49,50] The (M&bond;O) and (M&bond;N) bands were observed as new bands in the ranges 551-553 and 458-463 cm −1 , respectively. [3,4,[51][52][53][54][55][56][57][58] Zeolite Y shows absorption bands at 1022, 791 and 463 cm −1 , which may be assigned to asymmetric stretching, symmetric stretching and bending frequencies, respectively, of the Al-O-Si framework. The bands at ca 3600-3200 and 1641 cm −1 may be related to the adsorbed surface hydroxyl groups (stretching and bending).…”
