Sinteza i karakterizacija kompleksa Pd(II), Co(III) i Ni(II) sa kondenzacionim proizvodom 2-(difenilfosfino)benzaldehida i Žirarovog T reagensa

Complexes of Pd(II), Co(III) and Ni(II) with the condensation derivative of 2-(diphenylphosphino)benzaldehyde and Girard’s T reagent were synthesized, characterized, and their antimicrobial activities and magnetic properties were evaluated. The ligand, Pd(II) and Co(III) complexes were characterized by elemental analysis, IR and NMR spectroscopy, and X-ray crystallography. Ni(II) complexes were characterized by elemental analysis, IR spectroscopy and X-ray crystallography. In Pd(II) and Co(III) complexes, the deprotonated ligand was coordinated to the metal through the phosphorus, the imine nitrogen, and the carbonyl oxygen atoms. In the octahedral Co(III) complex, two ligand molecules were coordinated to metal ion, while the square-planar environment of Pd(II) complex was constituted of one tridentate ligand and chloride in the fourth coordination place. The ligand and Pd(II) and Co(III) complexes showed moderate antibacterial activity. In all the Ni(II) complexes the ligand is coordinated as tridentate via the phosphorus, the imine nitrogen and the carbonyl oxygen atoms while the remaining coordination positions are occupied with thiocyanato anions. Coordination of deprotonated phosphine ligand results in formation of square-planar complexes, while the octahedral complex was formed with protonated ligand. Results of magnetic measurements analyzed by Curie-Weiss law show paramagnetic behavior of investigated octahedral Ni(II) complex with effective magnetic moment μeff = 3.1 μB.Kompleksi Pd(II), Co(III) i Ni(II) sa kondenzacionim proizvodom 2-(difenilfosfino)benzaldehida i Žirarovog T reagensa su sintetisani, strukturno okarakterisani i ispitana su njihova magnetna i antimikrobna svojstva. Ligand, Pd(II) i Co(III) kompleksi su okarakterisani na osnovu rezultata elementalne analize, IC i NMR spektroskopije i rendgenske strukturne analize. Kompleksi Ni(II) su okarakterisani na osnovu rezultata elementalne analize, IC spektroskopije i rendgenske strukturne analize. U kompleksima Pd(II) i Co(III), deprotonovani ligand je koordinovan za jon metala preko atoma fosfora, azometinskog azota i karbonilnog kiseonika. U slučaju oktaedarskog kompleksa Co(III), dva molekula liganda su tridentatno koordinovana za metalni centar, dok u kvadratno-planarnom kompleksu Pd(II) okruženje oko centralnog metalnog jona čine tridentatno koordinovani ligand i hlorido ligand koji zauzima četvrto koordinaciono mesto. Ligand, Pd(II) i Co(III) kompleksi pokazuju umerenu antibakterijsku aktivnost.

Koordinacija deprotonovanog (cviter-jonskog) fosfinskog liganda dovodi do formiranja kvadratno-planarnih Ni(II) kompleksa, dok je u oktaedarskom Ni(II) kompleksu koordinovan pozitivno naelektrisani jon liganda.

Experimental and theoretical investigation of octahedral and square-planar isothiocyanato complexes of Ni(II) with acylhydrazones of 2-(diphenylphosphino)benzaldehyde

Octahedral and square-planar isothiocyanato complexes of Ni(II) with the condensation derivative of 2-(diphenylphosphino)benzaldehyde and Girard's T reagent were synthesized and characterized by elemental analysis, IR spectroscopy and X-ray crystallography. Results of magnetic measurements for octahedral Ni(II) complex were also reported. In all the complexes the ligand is coordinated as tridentate via the phosphorus, the imine nitrogen and the carbonyl oxygen atoms while the remaining coordination positions are occupied with thiocyanato anions. Coordination of deprotonated phosphine ligand results in formation of square-planar complexes, while the octahedral complex was formed with protonated ligand. Reaction energetics with both forms of ligand were studied by the means of DFT and results were in complete agreement with experimental observations. Furthermore, ligand field splitting analysis gave the deeper insight in the relationship of the isolated complex coordination environment and protonation of the ligand. (C) 2015 Elsevier Ltd.

Synthesis, characterization, DFT calculations, and antimicrobial activity of Pd(II) and Co(III) complexes with the condensation derivative of 2-(diphenylphosphino) benzaldehyde and Girard's T reagent

Complexes of Pd(II) and Co(III) with the condensation derivative of 2-(diphenylphosphino)benzaldehyde and Girard T reagent were synthesized, characterized, and their antimicrobial activities were evaluated. The ligand and the complexes were characterized by elemental analysis, IR and NMR spectroscopies, and X-ray crystallography. In both complexes, the deprotonated ligand was coordinated to the metal through the phosphorus, the imine nitrogen, and the carbonyl oxygen atoms. In the octahedral Co(III) complex, two molecules of ligands were coordinated to metal ion, while square-planar environment of Pd(II) complex was constituted of one tridentate ligand and chloride in the fourth coordination place. The ligand and complexes showed moderate antibacterial activity. The molecular structures of the obtained metal complexes and the relative stabilities of two stereoisomers of the ligand were calculated using density functional theory at the S12g/TZ2P level.Peer-reviewed manuscript: [http://farfar.pharmacy.bg.ac.rs/handle/123456789/3436
