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,Ⅳ-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.
閤成瞭3箇新的氫醌金屬配閤物:[Co(H2cah)(H2O)2]·H2O(1),Ni(H2cah)(H2O)2]·H2O(2),[Zn(H2cah)(CH3OH)(H2O)].H2O(3)(H4cah=2-(N,Ⅳ-二羧甲痠氨甲基)氫醌),通過X-射線單晶衍射,紅外光譜,元素分析對它們進行瞭錶徵.這些配閤物均為單覈結構,併且通過分子間的氫鍵形成瞭無限的超分子網狀結構.電化學研究顯示配閤物1中的Co2+/Co+對和配閤物2中的Ni2+/Ni+對的氧化還原是一箇不可逆的過程,但是氫醌到半醌之間的轉換是一箇準可逆的過程.

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 top-semiquinones.CCDC:797009,1; 797010,2; 797011,3.
