  • Fe<sup>III</sup> in a high-spin state in bis(5-bromosalicylaldehyde 4-ethylthiosemicarbazonato-κ<sup>3</sup> <i>O</i>,<i>N</i> <sup>1</sup>,<i>S</i>)ferrate(III) nitrate monohydrate, the first example of such a cationic Fe<sup>III</sup> complex unit

    The synthesis and crystal structure (100 K) of the title compound, [Fe(C10H11BrN3OS)2]NO3·H2O, is reported. The asymmetric unit consists of an octahedral [FeIII(HL)2]+ cation, where HL is H-5-Br-thsa-Et or 5-bromosalicylaldehyde 4-ethylthiosemicarbazonate(1−) systematic name: 4-bromo-2-[(4-ethylthiosemicarbazidoidene)methyl]phenolate}, a nitrate anion and a noncoordinated water molecule. Each HL ligand binds via the thione S, the imine N and the phenolate O atom, resulting in an FeIIIS2N2O2 chromophore. The ligands are orientated in two perpendicular planes, with the O and S atoms in cis and the N atoms in trans positions. This [Fe(HL)2](anion)·H2O compound contains the first known cationic FeIII entity containing two salicylaldehyde thiosemicarbazone derivatives. The FeIII ion is in the high-spin state at 100 K. In addition, a comparative IR spectroscopic study of the free ligand and the ferric complex is presented, demonstrating that such an analysis provides a quick identification of the degree of deprotonation and the coordination mode of the ligand in this class of metal compounds. The variable-temperature magnetic susceptibility measurements (5–320 K) are consistent with the presence of a high-spin FeIII ion with a zero-field splitting D = 0.439 (1) cm−1.

    报告了标题化合物 [Fe(C10H11BrN3OS)2]NO3-H2O的合成和晶体结构(100 K)。不对称单元由八面体 [FeIII(HL)2]+ 阳离子组成,其中 HL - 是 H-5-Br-thsa-Et 或 5-bromosalicylaldehyde 4-ethylthiosemicarbazonate(1-) 系统名称:4-bromo-2-[(4-ethylthiosemicarbazidene)methyl]phenolate},一个硝酸根阴离子和一个非配位水分子。每个 HL - 配体通过硫酮 S、亚胺 N 和苯酚 O 原子结合,形成 FeIIIS2N2O2 发色团。配体在两个垂直平面上定向,O 原子和 S 原子在顺式位置,N 原子在反式位置。这种[Fe(HL)2](阴离子)-H2O 化合物含有第一个已知的阳离子 FeIII 实体,其中含有两个水杨醛硫代氨基脲衍生物。在 100 K 时,FeIII 离子处于高自旋态。此外,研究人员还对游离配体和铁络合物进行了红外光谱对比研究,结果表明这种分析可以快速确定配体在这类金属化合物中的去质子化程度和配位模式。变温磁感应强度测量结果(5-320 K)与零场分裂 D = 0.439 (1) cm-1 的高自旋 FeIII 离子的存在相一致。

    Four dioxomolybdenum(VI) complexes were synthesized by reacting [MoO2(acac)(2)] with N-ethyl-2-(5-bromo-2-hydroxybenzylidene) hydrazinecarbothioamide (1), N-ethyl-2-(5-allyl-3-methoxy-2-hydroxybenzylidene) hydrazinecarbothioamide (2), N-methyl-2-(3-tert-butyl-2-hydroxybenzylidene) hydrazinecarbothioamide (3), and N-ethyl-2-(3-methyl-2-hydroxybenzylidene) hydrazinecarbothioamide (4). The molecular structures of 1, 2, and all the synthesized complexes were determined using single crystal X-ray crystallography. The binding properties of the ligand and complexes with calf thymus DNA (CT-DNA) were investigated via UV, fluorescence titrations, and viscosity measurement. Gel electrophoresis revealed that all the complexes cleave pBR 322 plasmid DNA. The cytotoxicity of the complexes were studied against the Ha 116 human colorectal cell line. All the complexes exhibited more pronounced activity than the standard reference drug 5-fluorouracil (IC50 7.3 mu M). These studies show that dioxomolybdenum(VI) complexes could be potentially useful in chemotherapy. (C) 2014 Elsevier B.V. All rights reserved.
