Synthesis, crystal structures, and antimicrobial activity of square-planar chloride and isocyanate Ni(II) complexes with the condensation product of 2-(diphenylphosphino)benzaldehyde and Girard's T reagent

Square-planar isocyanate and chloride Ni(II) complexes with tridentate PNO condensation product of 2-(diphenylphosphino)benzaldehyde and Girard's T reagent have been synthesized and their crystal structures were determined. These Ni(II) complexes with different monodentate ligands, chloride, cyanate, and thiocyanate were tested for their antimicrobial activities against pathogenic microorganisms. The ligand and Ni(II) complexes were active not only against laboratory control strains of bacteria and yeast, but also on clinical isolates of Escherichia coli and Pseudomonas aeruginosa strains resistant to most of the clinically used antibiotics.This is peer-reviewed version of the following article: Milenković, M.; Pevec, A.; Turel, I.; Milenković, M.; Čobeljić, B.; Sladić, D.; Krstić, N.; Andelković, K.
