摘  要:The new self-assembly tripodal hexadentate Schiff base compound, C27H30N4O3, derived from tris(2-aminoethyl)amine(tren) with salicylaldehyde and its manganese(Ⅲ) complex [(C27H27N403)Mn].CH3OH(1) were designed and synthesized by original self-assembly reaction at room temperature in the solution of methanol. Both the compounds were characterized by elemental analysis, IR spectrometry, UV-Vis spectroscopy and X-ray single crystal diffraction. It is noteworthy that the tripodal hexadentate Schiff base ligand effectively encapsulates the manganese(Ⅲ) ion and enforces a six-coordinate geometry in complex 1 with the apical nitrogen atom of tren-Schiff base remaining unbound to the metal. It is found that there are several intra-molecular hydrogen bonds in them(C-H…O and O-H…N). In addition, quantum chemistry calculations were also performed and discussed in detail. These results are consistent with the structural analyses of them.The new self-assembly tripodal hexadentate Schiff base compound, C27H30N4O3, derived from tris(2-aminoethyl)amine(tren) with salicylaldehyde and its manganese(Ⅲ) complex [(C27H27N403)Mn].CH3OH(1) were designed and synthesized by original self-assembly reaction at room temperature in the solution of methanol.
