In this work, syntheses of Schiff-base ligand, N-2-(6-methylpyridyl)-2-hydroxy-1-naphthaldimine (1) and its hitherto unknown chelate with a Ni(II) salt, bis[N-2-(6-methylpyridyl)-2-oxo-1-naphthaldimnato-k3N^N^O] nickel(II) (2) have been reported and characterized by spectral techniques (IR, 1H NMR, Mass). Solid state structures and non-covalent interactions persisting in 1 and 2 are studied by Density
在这项工作中,合成了席夫碱配体N-2-(6-methylpyridyl)-2-hydroxy-1-naphthaldimine ( 1 )及其与 Ni(II) 盐的迄今为止未知的螯合物双 [N-2- (6-甲基吡啶基)-2-oxo-1-naphthaldimnato-k 3 N^N^O] 镍(II) ( 2 )已被报道并通过光谱技术(IR、1 H NMR、Mass)表征。通过密度泛函理论 (DFT) 优化和赫什菲尔德表面 (HS) 分析研究了在1和2中持续存在的固态结构和非共价相互作用。X 射线衍射 (XRD) 研究显示平面席夫碱1的两性离子酮胺互变异构体形式以二聚体形式存在,由 C13 ̶ H13A ··· O1 i [(i) -x+1, -y, -z+1] 氢键和在螯合物2中围绕 Ni +2中心的扭曲八面体几何结构,其中整体晶体结构稳定性可归因于弱C—H ··· π、π ··· π堆积、范德华相互作用和C—H
