Quinoline sulfonamide complexes with different metals represent a new class of materials of great interest especially for their fotoluminiscent and biological activity (mostly antibacterial and antifungal activity). The emphasis of this work was to synthesize, characterize through X-ray and determine the antibacterial and antifungal proprieties of newly materials for medicinal chemistry applications based on Quinoline Sulfonamide Complexes Metals (QSCM). The synthesis of the QSCM materials is straight and efficient, in two steps: acylation of aminoquinoline followed by complexation with M2+ metal (Zn2+, Cd2+, Co2+, Cu2+). The synthesized quinoline sulfonamide complexes M2+ metals were characterized by X-ray diffraction on single crystal and by FTIR and NMR spectroscopy. The X-ray spectra prove unambiguously the structure of complexes, e.g for the Zn (II) complex crystallize in the monoclinic P21/n space group type, with a= 1.21602(5) nm, b = 1.55478(5) nm, c = 1.61786(6) nm, α = 90°, β = 106.007(2)°, γ = 90°, V= 2.9402(19) nm3and Z = 4.Sulfonamide acts as bidentate ligand trough Zn-Nquinoline and Zn-Nsulfonamide bonds, with atetrahedral coordination environment for Zn2+. The QSCMM2+ complexes were tested for their antibacterial and antifungal activity, having a good antibacterial activity against gram positive germStaphylococcus aureus,andgram negative germ Escherichia coli, and an excellent antifungal activity against fungus Candida albicans.
