Three new 3D metal-organic frameworks based on the tetrakis(imidazol-1-ylmethyl)methane and 1,4-benzenedicarboxylic acid ligands with transition metal (Zn/Cd/Co) and properties research

Three novel 3D metal-organic frameworks have been successfully synthesized by self-assembly of transition-metal salts with a flexible N-containing ligand and 1,4-dicarboxybenzene ligand. Complexes 1-3 have 3D structures with various topologies: complex 1 with (6·85)(64·82)(86) topology, complex 2 with a point symbol of (44·62)(44·66), complex 3 with 4·65 topological net directly. The solid-state fluorescence, magnetic property and thermal stability of these complexes have also been investigated.141
