Cadmium(II) coordination polymer based on flexible dithiolate-polyamine binary ligands system: Crystal structure, Hirshfeld surface analysis, antimicrobial, and DNA cleavage potential

Cadmium(II) compounds of the bis-cyanoethyl derivative (LCX) of Me8[14]aneC (LC): characterization and antibacterial studies

“…Due to the multifarious applications [1,2,3,4,5,6,7,8,9,10] of macrocyclic ligands, including differential behavior exhibited by their isomeric forms and their metal complexes in a wide variety of contexts, researchers continue to be fascinated by their chemistry and various applications, including in the development of metal-based drugs and as imaging agents. Relevant to the present study are recent reports describing the antibacterial activities of cadmium compounds [11,12,13,14]. These follow earlier studies, whereby cadmium(II) macrocyclic compounds were reported to exhibit potent antibacterial potential [13,14].…”

“…The molecular structure of the centrosymmetric molecule is shown in Figure 1. The 14-membered ring has an extended chair conformation and is stabilized by intramolecular amine-N-H…N(tertiary amine) hydrogen bonds [N1-H1n…N2 i ¼ 2.257(11) Å, N1…N2 i ¼ 2.9550(13) Å with angle at H1n ¼ 138.3 (11) for symmetry operation (i) 1-x, 1-y, 1-z]. The chirality at each of the C1 and C5 atoms is S and, being a centrosymmetric molecule, the chirality at each of the C1 i and C5 i atoms is R. The amine-N2 atom carries a cyanoethyl substituent with the N2-C3-C4-C7 torsion angle of 175.66 (12) being indicative of an þ antiperiplanar (þap) configuration.…”

Itaconic and citraconic acid directed thixotropic and self-healable supramolecular metallogels of M(ii) (M = Co, Cu, Zn, and Cd) for the growth-inhibitory potency against human pathogenic microbes

“…The bio-significances of itaconic and citraconic acid [40][41][42][43][44] along with the four metallic salts like Co(II), 45 Cu(II), 46,47 Zn(II), 47,48 and Cd(II) [48][49][50][51][52][53][54][55][56][57] instigate to explore the biological functionality of our synthesized metallogels. A few selective human pathogenic microbes, including four bacterial pathogens viz.…”
