Abstract

Silver(I) and zinc(II) complexes with N,N'-bis(trans-cinnamaldehyde)ethane-1,2-diamine (EnCinn) have been synthesized and characterized by elemental analysis, simultaneous thermogravimetric and differential thermal studies (TG-DTA), infrared (IR), H-1 and C-13 nuclear magnetic resonance (NMR) spectroscopic measurements and electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-QTOF-MS). Crystal and molecular structure descriptions were performed based on powder X-ray diffraction data. The AgEnCinn complex has a polymeric structure where the ligand bridges between two Ag(I) ions, while the ZnEnCinn complex has a monomeric structure with EnCinn acting as chelating ligand. Antimycobacterial assays over Mycobacterium tuberculosis showed the activity of the Ag(I) complex with Minimum Inhibitory Concentration (MIC) value of 22.7 mu mol L-1, while the Zn(II) complex was shown to be inactive over the same experimental conditions.
