Özet

Coordination compounds of compositions [Ni(bba) 2(bapen)] (1) and [Cu(bba) 2(bapen)]0.5H 2O (2), where bba = 2-benzoylbenzoate, bapen = N,N'-bis(3-aminopropyl)ethylenediamine, have been prepared. The crystal and molecular structure of (1) and (2) were determined by X-ray analysis. Nickel and copper atoms are six-coordinated by four N atoms of amine and O donor atoms of 2-benzoylbenzoate anions, whereas 0.5 water molecule is situated outside the coordination sphere in (2). The calculated A(OCO) values are consistent with presence of monodentate carboxylate. Thermal analysis show that the mass losses of 1 in the temperature ranges 240-343 °C correspond to the decomposition of bba ligands, while the mass losses of 2 in the temperature ranges 105-125 °C correspond to the decomposition of crystal lattice water molecule. © Springer Science+Business Media, LLC 2012.
