用Ni(salen)与铵盐NH_4X(X=SCN、Cl、Br、I或I_3)在乙醇中反应,分别制得了如下组成的新化合物:2Ni(salen)·NH_4SCN、2Ni(salen)·NH_4Cl、2Ni(saien)·NH_4Br·C_2H_5OH、2Ni(salen)·NH_4I·C_2H_5OH和3Ni(salen)·2NH_4I_3·C_2H_5OH,并以热重、摩尔电导、磁化率、红外和紫外可见光谱等方法对加合物进行了性质表征.研究结果表明,在这些加合物中,Ni(salen)的四方平面结构仍然保持,没有形成新的轴向Ni—X配键.讨论了加合物中的一种新型键合方式,它是以Ni(salen)的酚氧与NH_4X中的铵离子形成氢键.
The new compounds with the following composition were prepared by the reaction of Ni (salen) with NH_4X (X = SCN, Cl, Br, I or I_3) 2Ni (saien) · NH_4Br · C_2H_5OH, 2Ni (salen) · NH_4I · C_2H_5OH and 3Ni (salen) · 2NH_4I_3 · C_2H_5OH were synthesized and characterized by thermogravimetry, molar conductance, magnetic susceptibility, infrared and UV- The results show that the tetragonal planar structure of Ni (salen) remains in these adducts, and no new axial Ni-X coordinate bond is formed.A novel bond in adduct is discussed Way, it is the Ni (salen) phenolic oxygen and NH_4X hydrogen ions in the formation of hydrogen bonds.
