Synthesis, Crystal Structure, and Antimicrobial Activity of a Novel Trinuclear Cadmium(II) Complex Derived From 2-Ethoxysalicylaldehydethiosemicarbazone

“…Idealized H atoms were refined with isotropic displacement parameters set to 1.2 (1.5 for methyl groups) times the equivalent isotropic U values of the parent atoms. The lattice water molecules are disordered over three sites, with occupancies of 0.40(1), 0.40(1), and 0.20 (1). The crystallographic data for the complex are listed Table 1.…”

“…[1][2][3] In the last few decades, metal complexes with Schiff bases have attracted considerable attention due to their remarkable biological activity, such as antifungal, antibacterial, and antitumor. [4][5][6] It has been shown that the Schiff base complexes derived from salicylaldehyde and its derivatives, bearing the N 2 O, N 2 S, NO 2 , or NSO donor sets, have interesting biological activity, [6][7][8] however, the metal complexes and the biological activity of the Schiff base 2-ethoxysalicylaldehydethiosemicarbazone (HL; Scheme 1) de- rived from 3-ethoxysalicylaldehyde and thiosemicarbazide, has never been reported.…”

Synthesis, Structure, and Properties of Dicopper Complex With Imidazole-Containing Polyamine Ligand

“…[1][2][3][4][5][6][7][8] In particular, the molecule/anion recognition has attracted increasing interest. [4][5][6][7][8] For example, we have reported several macrocyclic complexes, which could recognize and fix deprotonated imidazole molecule, and act as model compounds of Cu 2 Zn 2 -SOD.…”

Synthesis, crystal structure, and antimicrobial activity of a novel chlorido-bridged dinuclear manganese(III) complex derived from N,N′-bis(5-methylsalicylidene)diethylenetriamine

“…[1][2][3] In recent years, metal complexes of Schiff bases have attracted considerable attention due to their interesting biological activity, such as antifungal, antibacterial and antitumor. [4][5][6] Schiff base complexes derived from salicylaldehyde and its derivatives with primary amines, bearing the N 2 O, N 2 S, NO 2 or NSO donor sets, have particular biological activities.…”
