A series of new hydrazone complexes were prepared and perfectly elucidated to be 1:1 molar ratio with Cd(II) complex, while 1:2 (M:L) with Co(II), Ni(II) and Cu(II) complexes. The bidentate form of bonding was proposed for all complexes, either in octahedral or square-planer geometry with the Ni(II) complex. The UV-Vis spectral data as well as the magnetism of complexes (except Cd(II) one) suggested
制备了一系列新型腙配合物,并完美阐明与Cd(II)配合物为1:1摩尔比,与Co(II)、Ni(II)和Cu(II)配合物为1:2 (M:L)配合物. 对所有配合物提出了双齿键合形式,无论是八面体还是方形平面几何形状的 Ni(II) 配合物。UV-Vis 光谱数据以及配合物的磁性(除了 Cd(II))表明中心原子周围配合物的几何形状以及配体场参数(10D q, B & β)。此外,根据其 ESR 谱计算 Cu(II) 配合物的自旋哈密顿参数归因于 S = 1/2 和 I = 3/2。对选定的配合物进行 XRD 和 SEM 分析,Ni(II)配合物的粒径呈纳米级。DFT方法用于在价双zeta极化基组和相关一致基组下优化配体及其配合物。配体表现出对 O(11) 和 O(12) 原子有利的特性,如取向、亲核性和电荷,这有助于它们优先协调。H 2 的遗传毒性PHNH 配体及其 Cd(II)、Cu(II)

Consequently, the ligand showed a well distribution for C(8)-O(11) and C(13) = O(12) groups, which promotes their coordination easily without twisting or strain for the bonds. The electrostatic potential confirms nucleophilicity of O(11) and O(12) atoms, which improved after coordination with Cr(III) and Co(II) ions due to M → Lcharge transfer. The dipole moment of the ligand (4.08 debye) predicts a distinguish
