SYNTHESIS AND REACTIVITY IN INORGANIC AND METAL-ORGANIC CHEMISTRY
Two new sets of Cu(II) complexes with newly synthesised benzilic and mandel
ic hydrazone derivatives were prepared in the mole ratios 1:1 and 1:2 (Cu:L
). The structure of the complexes was identified on the basis of the data o
btained from elemental and thermal analyses as well as IR, UV-visible, ESR
spectra, and X-ray diffraction. The results indicate that the ligands are t
ightly bound to the metal ion through the phenolic OH oxygen, the azomethin
e nitrogen, and the enolic OH oxygen in case of the 1:1 complexes while for
the 1:2 complexes the enolic OH group did not participate in bonding. The
complexes have elongated octahedral as well as square-planar symmetries.
