xylyl-linked imidazolium salts (7–10) and their respective Ag(I)-N-heterocycliccarbene (NHC) complexes (11–14) have been synthesized and characterized by a number of spectral and analytical techniques. Molecular structure of complexes 13 and 14 were established by single‐crystal X-ray diffraction method. The in vitro anticancer activity of all imidazolium salts and their Ag(I)-carbene complexes were investigated
