Three Cd(II) complexes based on pyridine containing mercapto-triazole and aromatic multi-carboxylates: Syntheses, structures and luminescent properties
“…In the last two decades, a large number of supramolecular assemblies using the derivatives of isophthalic acid (H 2 ip) as functional groups have been reported in the literature [4][5][6][7][8]. However it is still anticipated that modifications at the 5-position may afford different supramolecular network in view of their electronic effect.…”

“…So it is a versatile and variable ligand that can bind metal ions in different directions. [31][32][33][34][35][36][37][38] and intriguing in the field of pharmacology due to the discovery of their antimicrobial properties. The biological activity of coordination compounds with O-donor ligand isophthalato (IsoPht) has been studied.…”
A mixed ligand Cd(II) complex [Cd(IsoPht)(TEA)H2O]·3H2O was synthesized for the first time by using isophthalic acid (H2IsoPht) and tetradentate triethanolamine (TEA) and characterized by X-ray single-crystal diffraction, FT-IR, and thermogravimetric analysis (TGA). This novel complex crystallizes in the triclinic system with P-1 space group and distorted monocapped trigonal prismatic geometry. The Cd(II) has seven coordinates with bidentate IsoPht, a TEA in the tetradentate mode, and an aqua ligand. The fluorescence properties of the Cd(II) complex and TEA ligand were investigated at room temperature. The present Cd(II) complex was also tested for its antimicrobial activity by in vitro agar diffusion method against some Gram-positive and Gram-negative bacteria and a fungus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
