In the title complex, [NiSm(C(19)H(20)N(2)O(4))(NO(3))(3)(CH(4)O)(2)]·2CH(3)OH, the Ni(II) ion is coordinated by two O atoms and two N atoms of a deprotonated Schiff base ligand and by two O atoms of two methanol ligands in a slightly distorted octa-hedral geometry. The Sm(III) ion is coordinated by six O atoms from three chelating nitrate ligands and four O atoms from a Schiff base ligand in 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 (10) sheets.
在标题配合物[NiSm(C₁₉H₂₀N₂O₄)(NO₃)₃(CH₄O)₂]·2CH₃OH中，Ni(II)离子由一个去质子化席夫碱配体的两个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。Sm(III)离子在扭曲的双帽四方反棱柱环境中由三个螯合硝酸根配体的六个O原子和一个席夫碱配体的四个O原子配位。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(10)层。
