• W2988337259 abstract "The new α‐keto‐stabilized phosphorus ylide Ph 3 PCHC(O)PhCN ( Y ) was synthesized by addition of triphenylphosphine to 2‐bromo‐4′‐cyanoacetophenone, followed by treatment with NaOH 10%. Reaction of ligand ( Y ) with methanolic solution of mercury(II) halides under mild conditions yielded the binuclear complexes [Y·HgX 2 ] 2 [X=Cl ( 1 ), Br ( 2 ), I ( 3 )]. The new organic/inorganic composite polymer [Hg(NO 3 ) 2 (Y)] n ( 4 ) was synthesized by the reaction of mercury(II) nitrate with the phosphorus ylide Y . Compounds synthesized were characterized by Fourier‐transform infrared, 1 H, 31 P, and 13 C nuclear magnetic resonance spectroscopic methods, which confirmed the coordination of ylide to the metal center through the ylidic carbon atom. Single‐crystal X‐ray structures of phosphorus ylide Y and polymeric complex 4 were also determined and the crystallographic data of complex 4 showed that the title complex has an infinite one‐dimensional structure. Furthermore, the electronic and molecular structures of complexes 1 – 3 were investigated at the BP86/def2‐SVP level of theory, indicating an increasing trend for C→M bond lengths: Hg 2 I 2 > Hg 2 Br 2 > Hg 2 Cl 2 in [Y→HgX 2 ] 2 (X = Cl, Br, I) complexes. In addition, the antibacterial activity of ligand Y and all complexes using the agar disc diffusion method was examined against both selected gram‐positive and gram‐negative bacteria. Results indicated that the ligand Y and complexes 1 and 4 show good antibacterial effect against gram‐positive bacteria tested; besides, the inhibition zones of complexes were significantly larger than those of chloramphenicol as standard." @default.
