Abstract (en)
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.
Abstract (sr)
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. Kod svih Ni(II) kompleksa ligand je tridentatno koordinovan za jon metala preko P, N i O atoma, a preostala koordinaciona mesta zauzimaju izotiocijanato ligandi. 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. Rezultati magnetnih merenja ukazuju na paramagnetična svojstva ispitivanog oktaedarskog Ni(II) kompleksa čiji izmereni efektivni magnetni momenat iznosi 3,1 μB.
