In the title dinuclear complex, [NiLa(C(19)H(20)N(2)O(4))(NO(3))(3)(CH(3)OH)(2)]·2CH(3)OH, the Ni(II) ion is coordinated by two O atoms and two N atoms of a Schiff base ligand and by two O atoms of two methanol ligands, forming a slightly distorted octa-hedral geometry. The La(III) ion is coordinated by six O atoms from three chelating nitrate ligands and four O atoms from the Schiff base ligand, forming a distorted bicapped square-anti-prismatic environment. In the crystal structure, inter-molecular O-H-O hydrogen bonds connect complex mol-ecules and methanol solvent mol-ecules, forming a two-dimensional network.
在双核配合物[NiLa(C₁₉H₂₀N₂O₄)(NO₃)₃(CH₃OH)₂]·2CH₃OH中，Ni(II)离子由席夫碱配体的两个O原子和两个N原子以及两个甲醇配体的两个O原子配位，形成略微扭曲的八面体几何构型。La(III)离子由来自三个螯合硝酸根配体的六个O原子和来自席夫碱配体的四个O原子配位，形成扭曲的双帽四方反棱柱环境。在晶体结构中，分子间的O-H-O氢键连接配合物分子和甲醇溶剂分子，形成二维网络。
