Synthesis and 1-D Double Line Supramolecular Structure of a Ni(II) Complex with N-alkylated Dien
摘要:
A novel N-alkylated diethylenetriamine ligand L center dot 3HCl (L=N, N'-bis(4-methoxylbenzyl)-diethylenetriamine) and its mononuclear Ni(II) complex [Ni(L) phenCl] ClO4 (1) ( phen = o-phenanthroline) were synthesized and spectroscopically characterized. X-ray analysis indicates that octahedral geometry of the Ni( II) center is finished by three N atoms of dien moiety of the ligand in meridional fashion, two N atoms of phen and one Cl anion. Along the a axis, the neighboring molecules are connected via hydrogen bonds involving ClO4- anions and N-H groups of the ligands, thus forming a 1-D linear structure which is further connected to the other symmetry-related line via pi center dot center dot center dot pi stacking interactions of phen rings. The steric effect related to the molecular structure of L has been discussed.
