Abstrakt: The Ni(II) complex based on (4Z)-4-[(2-diethylaminoethylamino)methylene]-5-methyl-2-phenylpyrazole-3-one (HL), being the condensation product of 5-hydroxy-3-methyl-1-phenylpyrazole-4-carbaldehyde with N,N-diethylethylenediamine, is synthesized. By the elemental analysis and IR spectroscopy it is found that the nickel complex has the composition Ni(L)CH3COO·CH3OH·H2O. The crystal and molecular structures of the complex are determined by single crystal Xray diffraction (XRD). From the XRD data it follows that the monochelate Ni(II) complex has a distorted octahedral structure due to bonds with a monodentate acetate anion and methanol and water molecules.
