“…The broad peak at 3247 cm –1 is attributed to the mixed stretching vibrations of N–H of the oxamide group in 2bbpum and O–H in H 2 O . Two absorption peaks, 1367 and 1550 cm –1 , are ascribed to the symmetric and asymmetric stretching vibrations of the carboxylate group in the iip 2– ligand, respectively. − The stretching vibration of the oxamide group in 2bbpum locates at 1650 cm –1 …”

In this work, a novel Mn(II) chain coordination polymer (Mn-CP), {[Mn(iip)(2bbpum) 0.5 (H 2 O) 3 ]•2H 2 O} n [H 2 iip = 5-iodoisophthalic acid, 2bbpum = N,N′-bis(2-pyridinemethyl)oxamide] was synthesized under ambient conditions. Mn-CP further assembles into a 3D supramolecular architecture through hydrogen bonds, halogen bonds, and ππ stacking interactions. The composite Mn-CP/nafion membrane has low activation energy for proton transfer, which results in its temperature-insensitive proton conductivity. The cyclic voltammetry demonstrates that the Mn-CP electrode (Mn-CP/GCE) shows quite different redox properties in 0.1 M H 2 SO 4 and 0.1 M PBS aqueous solutions. The Mn-CP/GCE exhibits a couple of irreversible redox peaks with an oxidation peak potential suitable for the nitrite oxidation in 0.1 M H 2 SO 4 . Quite differently, in the PBS aqueous buffer solution, the Mn-CP electrode has a couple of irreversible redox peaks. The reduction peak potential is appropriate for the H 2 O 2 reduction. So, the Mn-CP/GCE can be used not only in the electrocatalytic oxidation of NO 2 − but also in the electrocatalytic reduction of H 2 O 2 . The amperometric response reveals that the Mn-CP/GCE exhibits high-selective and extremely sensitive oxidation sensing of NO 2 − and reduction sensing of H 2 O 2 . The exponential detection range is 0.01−20 mM for NO 2 − and 0.01−10.5 mM for H 2 O 2 . The linear detection range for both H 2 O 2 and NO 2 − is 0.01−0.10 mM. The detection limit is 1.865 μM for NO 2 − and 8.57 μM for H 2 O 2 . The Mn-CP/GCE exhibits high electrochemical stability and fine reproducibility. Moreover, the strategy can be translated to a portable screen-printed electrode (SPE). The Mn-CP/SPE shows more sensitive sensing to NO 2 − and H 2 O 2 than Mn-CP/GCE. Moreover, it can detect NO 2 − and H 2 O 2 efficiently in the real-world samples. So, Mn-CP may be a potential dual nonenzymatic electrochemical sensory material for NO 2 − via oxidation sensing and H 2 O 2 via reduction sensing.

The reaction of NiCl2 and 3‐hydrazine‐4‐amino‐1,2,4‐triazole (Hatr) in the mixed solvent of EtOH and H2O yielded a dimer compound ([Ni2(Hatr)2(H2O)2(EtOH)2Cl2]Cl2·EtOH) with water and EtOH molecules coordinated to nickle ions. It crystallized in trigonal space group R‐3, a=b=29.67(1) Å, c=8.95(7) Å, β=120(1)°, as determined by single‐crystal X‐ray diffraction. Then, they were fully characterized by the IR spectroscopy, differential scanning calorimetry (DSC), thermogravimetry (TG), and elemental analysis.
