Spectroscopic, magnetic, and electrochemical studies of a dimeric N-substituted-sulfanilamide copper(II) complex. X-ray and molecular structure of the Cu2(N-(pyridin-2-yl)biphenyl-4-sulfonamidate)4 complex

Crystal structure, Hirshfeld surface analysis, spectroscopic and biological studies on sulfamethazine and sulfaquinoxaline ternary complexes with 2,2′-biquinoline

“…Sulfonamide compounds are recognized for their biological properties [1][2][3][4][5][6] and their different coordination modes 5 . A wide variety of metal complexes with N-sulfonamides derivatives has also been studied for their polymer stabilization capacity 2 , magnetic behavior [7][8][9][10] , electrochemical properties 8,9,11 and luminescent emission 12,13 . Some complexes with sulfaquinoxaline (SQO) or sulfamethazine (SMT) as ligands (see Scheme 1) have been reported as effective chemotherapeutic agents.…”

“…materials, pharmaceuticals). In the case of sulfonamide metal complexes, inter and intramolecular hydrogen bonding, π•••π, and C-H•••π interactions have a great influence on the crystal lattice stabilization 1,3,5,8,17 . The Hirshfeld surface analysis is a powerful tool for visualizing and quantifying the contribution of such intermolecular interactions to supramolecular assemblies [18][19][20] .…”
