| Complexes of MⅡ (M= Co, Ni, Zn) with 2-[N,N-Bis(carboxymethyl) Aminomethyl] Hydroquinone: Syntheses, Crystal Structures and Electrochemical Properties | |
| 摘要: 合成了3个新的氢醌金属配合物：[Co(H2cah)(H2O)2]·H2O (1)，Ni(H2cah)(H2O)2]·H2O (2)，[Zn(H2cah)(CH3OH)(H2O)]·H2O (3)(H4cah=2-(N，N-二羧甲酸氨甲基)氢醌)，通过X-射线单晶衍射，红外光谱，元素分析对它们进行了表征。这些配合物均为单核结构，并且通过分子间的氢键形成了无限的超分子网状结构。电化学研究显示配合物1中的Co2+/Co+对和配合物2中的Ni2+/Ni+对的氧化还原是一个不可逆的过程，但是氢醌到半醌之间的转换是一个准可逆的过程。 | |

| Abstract: Three p-hydroquinone-metal complexes: [Co(H2cah)(H2O)2]·H2O (1), Ni(H2cah)(H2O)2]·H2O (2) and [Zn(H2cah)(CH3OH)(H2O)]·H2O (3), where H4cah=2-[N, N-bis(carboxymethyl)aminomethyl]hydroquinone, have been synthesized and characterized using X-ray diffraction single crystal structure determination, IR and elemental analysis, All these compounds were mononuclear structure, and complexes form an infinite supramolecular networks by intermolecular hydrogen bond. The cyclic voltametric analysis of 1 and 2 show that the electron transfer in the electrode reaction is irreversible for M(Ⅱ)/M(Ⅰ) redox couples (M=Co, Ni) while reversible for process of interchange from p-hydroquinone to p-semiquinones.
