dc.description.abstractCoordination complexes of transition metal cations (Co-II, Ni-II, Cu-II and Zn-II) containing coumarilate and N,N'-diethylnicotinamide were synthesized. The structural characterization and thermal behaviour analysis of novel samples synthesized were conducted through elemental analysis, magnetic susceptibility, solid-state UV-Vis, direct and injection probe mass spectra, FTIR spectra, thermoanalytic TG-DTG/DTA and single crystal X-ray diffraction methods. The structural details of single crystals of [Co(dena)(2)(H2O)(4)](coum)(2) (I) and [Cu(coum)(2)(dena)(2)(H2O)(2)] (III) complexes were resolved completely. Moreover, the results of analysis obtained for [Ni(coum)(2)(dena)(2)(H2O)(2)] (II) and [Zn(dena)(2)(H2O)(4)](coum)(2) (IV) complexes were interpreted considering the samples with crystal structures defined and made assumptions about the structural details. It was determined that the complex of Co-II metal cation has salt-type structure and the coordination number of metal is accomplished to six as the sum of 4 mol of water and also 2 mol of N,N'-diethylnicotinamide ligands in trans position located within the coordination sphere. It was observed that 2 mol of coumarilate anions are located outside the coordination sphere and have stabilized to the charge (2+) of metal. The Cu-II complex has totally molecular structure, and the coordination sphere of metal cation was 6 as the sum of 2 mol of water, 2 mol of N,N'-diethylnicotinamide and 2 mol of monoanionic monodentate coumarilate ligands. All ligands have been located in -trans position. The geometry of both complex structures is distorted octahedral. It is assumed that the Ni-II complex structure is isostructural with Cu-II complex structure and also does Zn-II complex with Co-II structure. It was determined that the decomposition products obtained from thermal analysis are the oxides of related metal cations.
