In the title heteronuclear Zn(II)-Tb(III) complex (systematic name: {6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-id-yne)]diphenolato-1κ(4)O(6),O(1),O(1'),O(6')}:2κ(4)O(1),N,N',O(1')-μ-nitrato-1:2κ(2)O:O'-dinitrato-1κ(4)O,O'-terbium(III)zinc(II)), [TbZn(C(18)H(18)N(2)O(4))(NO(3))(3)], with the hexa-dentate Schiff base compartmental ligand N,N'-bis-(3-methoxy-salicyl-idene)ethyl-enediamine (H(2)L), the Tb 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 Tb(III) center has a ninefold coordination environment of O atoms, involving the phenolate O atoms, two meth-oxy O atoms, two O atoms from two nitrate ions and one from the bridging nitrate ion. Weak inter-molecular C-H⋯O inter-actions generate a two-dimensional layer structure.
在标题中的异核锌（II）-铽（III）配合物（系统名称：{6,6'-二甲氧基-2,2'-[乙烷-1,2-二亚基双（亚氨甲基）]二酚根合-1κ(4)O(6),O(1),O(1'),O(6')}:2κ(4)O(1),N,N',O(1')-μ-硝酸根-1:2κ(2)O:O'-二硝酸根-1κ(4)O,O'-铽（III）锌（II）），[TbZn(C₁₈H₁₈N₂O₄)(NO₃)₃]中，铽和锌原子由席夫碱配体的两个酚氧原子和一个硝酸根离子三重桥连。五配位的锌原子呈四方锥几何构型，其供体中心包括两个亚胺氮原子、两个酚氧原子和一个桥连硝酸根的氧原子。铽（III）中心具有由氧原子构成的九重配位环境，涉及酚氧原子、两个甲氧基氧原子、来自两个硝酸根离子的两个氧原子和来自桥连硝酸根离子的一个氧原子。弱的分子间C-H⋯O相互作用产生二维层状结构。
