“…The results of elemental analysis were in good agreement with the theoretical components. The IR bands at 1185 cm -1 and 1406 cm -1 for Ni( ) complex were attributed to the v(C-N) and v(C=N) vibrations of imidazole rings, respectively [39][40][41][42][43]. The asymmetric and symmetric stretching vibrations of coordinated carboxylates were observed at 1230 cm -1 and 1494 cm -1 .…”

A new mononuclear Ni(II) complex, [Ni(p-MOPhH 2 IDC) 2 (H 2 O) 2 ], was synthesized by the reaction of p-MOPhH 3 IDC (2-(4-methoxyphenyl)-1H-imidazole-4,5-dicarboxylic acid) and Ni(NO 3 ) 2 •6H 2 O under solvothermal conditions and characterized by single-crystal X-ray diffraction, elemental analysis, IR and UV-vis spectroscopy. The structure analysis revealed that the nickel center was six-coordinated octahedron coordination geometry. The electrochemical properties of the Ni(II) complex-doped carbon paste electrode (Ni-CPE) were investigated. For electrocatalytic HER (hydrogen evolution reaction), linear sweep voltammetry curves at different temperatures were determined. The polarization curve shows that the η 10 298K (overpotential, 10 mA cm -2 ) of the Ni-CPE was positively shifted by 265 mv compared with the bare-CPE (without complex). The Tafel slope of the Ni-CPE was 187 mV dec -1 . These indicated that the Ni-CPE was effective for HER electrocatalytic reaction. In addition, the electrochemical sensing performances of the Ni-CPE towards H 2 O 2 were found to have a linear response from 0.5 μM to 4.0 mM with a detection limit of 0.036 μM. The information obtained from this study will help to expand the application of Ni(II) complex in the eld of electrochemistry.

The development of low‐cost, high‐efficiency, stable, and structurally adjustable electrocatalysts for hydrogen evolution reaction (HER) is of great significance for energy conversion. In this study, two new Cu(I) coordination polymers (CPs), formulated as {[Cu(L1)](PF6)·CH2Cl2}n (1) and {[Cu2(L2)1.5(PPh3)](PF6)2}n (2) (L1 = 1,3‐bis[1‐(pyridin‐3‐ylmethyl) ‐1H‐benzimidazol‐2‐yl]propane, L2 = 1,4‐bis[1‐(3‐pyridylmethyl)‐1H‐benzimidazol‐2‐yl]butane), were synthesized by interfacial diffusion method and characterized by single‐crystal x‐ray diffraction and IR and UV–Vis spectra. Structural analysis shows that the CP‐1 is a one‐dimensional chain structure, whereas the CP‐2 is a two‐dimensional layered structure, which is due to the different coordination modes of ligands L1 (bridging chelation) and L2 (bridging). The electrocatalytic activity for HER of Cu(I) CPs was studied by preparing modified glassy carbon electrodes (CP‐1/GCE and CP‐2/GCE). Electrochemical HER studies manifest that in 0.5 M H2SO4, the overpotential (η10298K) and Tafel slope (b 298K) are −769 mV and 173 mV dec−1 for CP‐1/GCE, −933 mV and 301 mV dec−1 for CP‐2/GCE, and −930 mV and 298 mV dec−1 for bare/GCE, respectively. The η10298K and b298K of CP‐1/GCE were significantly positive shifted and decreased compared with the bare/GCE, indicating that CP‐1/GCE has significant electrocatalytic activity and electrocatalytic HER activity order is CP‐1/GCE > CP‐2/GCE ≈ bare/GCE. This work provides an important reference for the application of non‐noble metal CPs in the field of electrocatalysis.
