САЖЕТАК / ABSTRACT:
The coordination properties of 3-(4-chlorophenyl)-1H-pyrazole (HL) was investigated and its complex with Ni(II) ion was synthesized. The structure of the ligand was proven using SC-XRD, while both the ligand and the complex were characterized by spectroscopic, and thermogravimetric measurements. The purity and composition of the complex were confirmed by PXRD, elemental analysis, and conductometric measurements. Besides, the search for CSD was made to establish the frequency of different coordination modes of similar compounds. It was found that monodentate coordination of the neutral ligand molecule or the exo-bidentate one in the case of the deprotonation of the pyrazole ring is possible. Based on the results obtained, the formula [Ni2(μ-L)2(OH)2(H2O)2]·2H2O and the bridging bidentate coordination of the monoanionic form of the ligand via nitrogen atoms of the pyrazole ring was suggested.
