Ni(II) and Co(II) acetato complexes of pyrazole-pyridine based ligand: Synthesis, structure and thermal decomposition
Özet
Abstract: Two novel acetato complexes with NNN type planar bdmpp ligand, [Ni(OAc)(H2O)2(bdmpp)]OAc (1) and [Co(OAc)(H2O)2(bdmpp)]OAc (2) (bdmpp: 2,6-bis(3,5-dimethylpyrazolyl)pyridine) were synthesized and characterized by elemental analysis, IR spectroscopy and X-ray single-crystal diffraction analysis. Thermal stabilities of these complexes were studied by thermogravimetric and differential thermal analyses. The crystal structures of both complexes were also determined using single-crystal X-ray diffraction. It was found that complexes 1 and 2 possessed smilar octahedral coordination environment in which metal ions were coordinated by N donor atoms of bdmpp, two oxygens of aqua ligands and one oxygen atom from terminal bonding acetato ligand.
