在标题化合物中，ZnII-Eu Ⅲ配合物[系统名称：{6，6 ′-二甲氧基-2，2 ′-[乙烷-1，2-二基]二（次氮基亚甲基）]二酚-κ 4 O 1，O 1 ′，O 6，O 6 ′：2κ 4 O 1，N，N′，O 1 ′}-μ-硝酸根-1：2κ 2 O：O′-二硝酸根合-1 κ 4 O，O′-铕（III）锌（II）]，[EuZn（C18 H18 N2 O 4）（NO3）3]与六齿Schiff碱隔室配体N，N′-bis（3-甲氧基亚水杨基）乙二胺（H2 L）中，Eu和Zn原子通过Schiff碱配体的两个酚氧原子和一个硝酸根离子三重桥接。五配位的Zn原子呈四方锥构型，其给体中心为两个亚胺N原子、两个酚盐O原子和一个桥连硝酸盐O原子。EuIII中心具有九重O原子配位环境，包括酚盐O原子、两个甲氧基O原子、来自两个硝酸根离子的两个O原子和来自桥接硝酸根离子的一个O原子。弱的分子间C-H-O相互作用产生二维双层结构。
In the title heteronuclear ZnII–EuIII complex [systematic name: {6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato-κ4O1,O1′,O6,O6′:2κ4O1,N,N′,O1′}-μ-nitrato-1:2κ2O:O′-dinitrato-1κ4O,O′-europium(III)zinc(II)], [EuZn(C18H18N2O4)(NO3)3], with the hexadentate Schiff base compartmental ligand N,N′-bis(3-methoxysalicylidene)ethylenediamine (H2L), the Eu and Zn atoms are triply bridged by two phenolate O atoms of the Schiff base ligand and one nitrate ion. The five-coordinate Zn atom is in a square-pyramidal geometry with the donor centers of two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The EuIII center has a ninefold coordination environment of O atoms, involving the phenolate O atoms, two methoxy O atoms, two O atoms from two nitrate ions and one from the bridging nitrate ion. Weak intermolecular C—H⋯O interactions generate a two-dimensional double-layer structure.
