Özet
The novel one N-4 and two N4O2 containing hetero-trinuclear oxime metal complexes, [Co(L)(2)(H2O)(2)Mn-2(dafo)(4)](ClO4)(2) (1), [Co(L)(2)(H2O)(2)Mn-2(dafdione)(4)](ClO4)(2) (2), [Co(L)(2)(H2O)(2)Mn-2(dcbpy)(4)](ClO4)(2) (3) and [Co(L)(2)(H2O)(2)Mn-2(phen)(4)](ClO4)(2) (4), (where, L = N,N'-bis(ethyl-4-amino-1-piperidine carboxylate)-glyoxime, dafo = 4,5-diazafluoren-9-one, dafdione = 1H-cyclopenta[1,2-b:5,4-b']dipyridine-2,5-dione, dcbpy = 3,3'-dicarboxy-2,2'-bipyridine and phen = 1,10-phenanthroline) have been synthesized and characterized by UV-Vis, FT-IR spectra, magnetic susceptibility measurements, molar conductivity, X-ray powder techniques, mass spectra and their morphology studied by SEM measurements. The H-bonding (O-H center dot center dot center dot O) in the Mn(II)-Co(II)-Mn(II)-type hetero-trinuclear oxime metal complexes disappears, the Co(II) ion centered into the main oxime core by the coordination of the imino groups while the two Mn(II) ions coordinated to dianionic oxygen donors of the oxime groups and linked to the ligands of dafo, dafdione, dcbpy and phen.
