A dinuclear copper(II) complex, [CuII2(L)2] is afforded by the reaction of CuCl2·2H2O with a triazenido ligand, 1‐[(2‐carboxymethyl) benzene]‐3‐[2‐carboxybenzene] triazene (H2L). Structural investigation shows that the copper‐copper distance [2.3985(7) Å] is significantly shorter than the sum of the van der Waals radii of Cu (1.40 Å), suggesting that there are metal‐metal bonds in [CuII2(L)2]. In solid, there is a strong antiferromagnetic interaction between copper(II) ions (J = –135.6 cm–1). In homogeneous environment, [CuII2(L)2] shows electrocatalytic activities for hydrogen generation both from acetic acid with a turnover frequency (TOF) of 32 mol of hydrogen per mole of catalyst per hour [mol(H2)·mol–1(catalyst)·h–1] at an overpotential (OP) of 941.6 mV, and neutral buffer with a TOF of 512 mol(H2)·mol–1(catalyst)·h–1 at an OP of 836.7 mV.

1-[[(2-羧甲基)苯] -3- [2-羧苯]三氮烯双核铜(II)配合物的析氢合成,表征和电催化行为

CuCl 2 · 2H 2 O与三叠氮烯配体1 [[(2-羧甲基)苯] -3- [2-]反应生成双核铜(II)络合物[Cu II 2(L)2 ]。羧基苯]三氮烯(H 2 L)。结构研究表明,铜与铜的距离[2.3985(7)Å]明显短于Cu的范德华半径之和(1.40Å),这表明[Cu II 2(L )2 ]。在固体中,铜离子之间存在强反铁磁相互作用(J = –135.6 cm –1)。在均匀环境中,[Cu II 2(L)图2显示了乙酸在每分钟催化剂[mol(H 2· mol –1(催化剂)· h –1 ]的条件下从乙酸的产生氢的电催化活性,其周转频率(TOF)为32 mol氢。过电位(OP)为941.6 mV,中性缓冲液的TOF为512 mol(H 2· mol –1(催化剂)· h –1,且OP为836.7 mV。
