Figure 1From: Potential of silver against human colon cancer: (synthesis, characterization and crystal structures of xylyl (Ortho, meta, & Para) linked bis-benzimidazolium salts and Ag(I)-NHC complexes: In vitroanticancer studies)FT-IR overly spectra of bis -benzimidazolium dibromide precursors (5-7. 2Br). The peaks labeled as 3 in the red box indicate the overlap of tertiary N-atom of benzimidazolium ring by hydrated water molecules.Back to article page
