Schiff base derivatives have gained great importance due to revealing a great number of biological properties. Schiffbases were synthesized by treatment of 4‐amino‐1,5‐dimethyl‐2‐phenyl‐1H‐pyrazol‐3(2H)‐one (1) with various aldehydes in methanol at reflux. In addition, diamine was reacted with an aldehyde to yield the corresponding Schiffbases. The structures of synthesized Schiffbases were elucidated

Cu (II), Ni (II), Co (II), and Mn (II) acetato in addition to Cu (II) chloro and nitrato mixedligandcomplexes of 4-([quinolin-2-yl]methyleneamino)-1,2-dihydro-2,3-dimethyl-1-phenylpyrazol-5-one (L), as a primary ligand and 2,4-dihydroxy benzaldehyde (H2L), as a secondary ligand have been isolated. The structural features and geometrical arrangements of the synthesized mixedligandcomplexes were
Cu (II)、Ni (II)、Co (II) 和 Mn (II) 乙酸根以及 4-([quinolin-2-yl]methyleneamino)-1 的 Cu (II) 氯和硝基混合配体配合物,已分离出作为主要配体的2-二氢-2,3-二甲基-1-苯基吡唑-5-酮(L)和作为次要配体的2,4-二羟基苯甲醛(H 2 L)。通过元素分析、傅里叶变换红外光谱 (FT-IR)、电导率测量、紫外-可见光谱、磁矩测量、X 射线衍射和电子自旋共振对合成的混合配体配合物的结构特征和几何排列进行了鉴定。混合配体配合物的 ESR) 光谱和热重技术研究证实了 Cu (II)、Co (II)、Mn (II) 和 UO 2的摩尔比为 1:1:1(一级配体:M:二级配体)(二)螯合物。光谱技术还证实金属螯合物具有分子式(Cu[H 2 L][L][X] 2 ),其中X = Cl - ( 1 );NO 3 - ( 2 );
