  苯并咪唑配体在酸性介质中对碳钢的缓蚀作用：其与 Fe30 表面相互作用的 DFT 研究

  摘要：

  摘要 通过电化学和理论分析了 N,N'-双(苯并咪唑-2-基-甲基)胺(L1)和N,N'-双(苯并咪唑-2-基-甲基)羟乙胺(L2)的缓蚀作用。方法。数据显示配体在铁表面形成吸附层，遵循朗缪尔等温线（Δ G ads ° 为-32.96 kJ mol-1）；值大于-20 kJ mol-1但小于-40 kJ mol-1，属于物理吸附向化学吸附或综合吸附的转化阶段。这与电极表面的分形维数一致，由半圆的阻抗俯角估计，该表面被抑制膜的形成均匀覆盖。此外，配体的电子参数通过 DFT 分析，表明 L1 和 L2 具有缓蚀性能，通过其 HOMO 轨道将其 p 轨道电子密度交给金属 LUMO 以形成吸附层，这已通过配体与 Fe30 的相互作用在理论上得到证实。此外，我们收集了文献中报道的大约 70 种有机化合物的缓蚀数据，并将缓蚀数据与不同的抑制剂作图，表明胺配体是良好的缓蚀剂。

  日期：——

  A novel binuclear iron(III) complex [FeL[O 2 P(OPh) 2 ]} 2 ][ClO 4 ] 2 was synthesized and characterized by X-ray single-crystal structure analysis, where HL is bis(benzimidazol-2-ylmethyl)(2-hydroxyethyl)amine. The crystals are triclinic, space group P, with a = 11.523(9), b = 11.809(6), c = 13.406(4) Å, α = 68.52(4), β = 71.41(5), γ = 71.85(6)° and Z = 1. The structure shows that the iron(III) ions are bridged by the oxygen atoms of two L ligands and a phosphate ligand is terminally co-ordinated to each iron(III). Magnetic susceptibility measurements in the range 4.2–300 K and subsequent calculations based on an isotropic Heisenberg model suggest antiferromagnetic coupling between the iron(III) ions with J = -17.5 cm -1 .

  一种新颖的双金属铁(III)复合物 [FeL[O2P(OPh)2]}2][ClO4]2 被合成并通过X射线单晶结构分析进行了表征，其中HL为双(苯并咪唑-2-基甲基)(2-羟乙基)胺。晶体为 triclinic，空间群为 P，晶格参数为：a = 11.523(9)Å，b = 11.809(6)Å，c = 13.406(4)Å，α = 68.52(4)°，β = 71.41(5)°，γ = 71.85(6)°，Z = 1。结构显示铁(III)离子由两个L配体的氧原子桥接，并且每个铁(III)离子端部与磷酸盐配体配位。4.2–300 K范围内的磁化率测量及基于各向同性海森堡模型的后续计算表明铁(III)离子之间存在反铁磁耦合，J = -17.5 cm-1。
