摘 要:三(2-氨基乙基)胺分别与水杨醛、5-氯水杨醛反应,合成两个三{2-[(5-X-2-羟基苯亚甲基)亚胺]乙基}胺化合物,X:H(1),Cl(2)。经红外光谱、核磁共振1 H和13 C谱表征,X-射线衍射方法测定其晶体分子结构,化合物(1)为单斜晶系,P2(1)/c空间群;化合物(2)三斜晶系,P-1空间群。化合物(1)和(2)具有三足型结构,它们的构象分析表明,螺旋桨型结构的体系能比三足型结构更低,它们的体系能能差ΔE:969.57kJ/mol (1),926.00kJ/mol(2),非键作用能差ΔE:125.25kJ/mol(1),166.14kJ/mol(2),因此,螺旋桨型比三足型结构更稳定。为三足型配体与金属的配位化学研究提供有益的参考。Two tripodal compounds,tris{2-[(5-X-2-hydroxybenzylidene)imino]ethyl}amine,X=H(1),Cl(2)were synthesized by the raction of the tris(2-aminoethyl)amine with salicylaldehyde,5-chlorosalicylaldehyde respectively,which have been structurally characterized by IR,(1 H,13 C)NMR spectra,and their crystal molecular structure is determined by X-ray diffraction analysis method.The compounds(1)crystallizes in the monoclinic system,space groups P2(1)/c,and the compounds(2),crystallizes in the triclinic system,space group P-1.Their conformational analysis indicates that the system energy of propeller-type is lower than the tripodal structure.ΔE(1),969.57kJ/mol;ΔE(2),926.00kJ/mol.Their non-bonded interaction energy difference of(1)is ΔE(1),125.25kJ/mol,and of(2)isΔE(2),166.14kJ/mol.Therefore,the propeller framework has a more stable than the tripodal-type.It provides a useful reference for the coordination study between tripodal ligands and metals.
