(3,3)-Connected Three-dimentional Supramolecular Metal Organic Polyhedral Based on Nanometresized Ligand with Magnetism Properties

Abstract

A three-dimentinal metal organic framework [Co₂(L)Cl(DMF)₂(H₂O)](DMF)₃(H₂O)₃ based on the nano-metresized ligand 4,4′,4″-[1,3,5-benzenetriyltris(carbonylimino)]trisbenzoic acid was synthesized, and characterized by means of single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy, thermogravimetry analysis and magnetism. This obtained structure can be considered to be constructed from 2D layer, which displays the topology of hbc based on Co₂(COO)₃ secondary building unit, and further to be linked into a 3D supramolecular architecture by N—H···O hydrogen bonds. The magnetism of the complex was carried out, which shows ferromagnetic exchange interactions.
