Abstract A novel series of tetraaza nickel (II) macrocyclic complexes was prepared via template condensation involving the ligand 2‐[4‐bromo‐2‐(2‐oxo‐1,2‐diphenyl‐ethylideneamino)‐phenylimino]‐1,2‐diphenyl‐ethanone (ML) and selected diamines, such as 4‐chloro 1,2‐phenylenediamine, 4‐bromo 1,2‐diaminotoluene, 4‐nitro 1,2‐diaminopropane, ethylenediamine, in presence NiCl 2 .6H O. The its resulting were characterized through elemental analysis, molecular weight determination, a range spectral techniques, including IR, electronic spectra, 1 H NMR, mass spectrometry, X‐ray powder diffraction, DFT‐assisted structural characterization.

Due to the lack of UV-protective properties for cotton textiles and potential cause microbes their users, we synthesized benzimidazole Schiff base derivative (BZI) namely N-((1H-benzo[d]imidazol-2-yl)methyl)-1-(4-fluorophenyl)methanimine V(III), Fe(III), Co(II), Ni(II), Cu(II) complexes as UV protection antimicrobial agents textile. Several techniques investigated these compounds: 1H, 13C NMR, IR, UV–Vis, elemental analysis, DTA, TGA. The ligand behaved a bidentate ligand. prepared its are used treat fabrics (CFs) by immersing fabric in solution samples under ultrasonic. treated were using IR SEM-EDX analysis. UPF values obtained. results showed that with Fe(III) had excellent 50+. disc diffusion method evaluated fabric’s activity. antifungal activities CFs demonstrated Co(II)-BZI-CF was active on C. albicans an inhibition zone 12 mm, while other inactive A. flavus. V(III)-BZI-CF Fe(III)-BZI-CF no activity against S. aureus E. coli bacteria gave between 10 17 mm. Unlike previous studies primarily focused either or metal separately, this research integrates both functionalities synthesizing applying them textiles, demonstrating enhanced selective
