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.

Ni(II)与(4Z)-4-[(2-二乙基氨基乙基氨基)亚甲基]- 5-甲基-2-苯基吡唑-3-ONE络合物的合成和晶体结构

基于 (4Z)-4-[(2-diethylaminoethylamino)methylene]-5-methyl-2-phenylpyrazole-3-one (HL) 的 Ni(II) 配合物，是 5-羟基-3-甲基的缩合产物合成了-1-苯基吡唑-4-甲醛与N,N-二乙基乙二胺。通过元素分析和红外光谱发现，镍配合物的组成为Ni(L)CH3COO·CH3OH·H2O。复合物的晶体和分子结构由单晶 X 射线衍射 (XRD) 确定。从 XRD 数据可以看出，由于与单齿乙酸根阴离子以及甲醇和水分子的键合，单螯合 Ni(II) 配合物具有扭曲的八面体结构。
