Figure 2From: 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 bis (hexaflourophosphate) precursors (8-10. 2PF 6 ). The weak FT-IR signals labeled as 3 in the red box represent the pure modes of tertiary N-atom in benzimidazolium ring.Back to article page
