Abstract

Abstract: Using the N-heterocyclic building block 5, 5′-di(pyridin-3-yl)-3, 3′-bi(1, 2, 4-triazole) (3, 3′-H2 dbpt), four 3-D coordination polymers with diverse connectivity, [M(3, 3′-dbpt)]n, M=Co (1 ), M=Ni (2 ), M=Zn (3 ), and [Cd2 (3, 3′-dbpt)Cl2 ]n (4 ), were constructed. By changing the central metal ions, 3, 3′-H2 dbpt had three different coordination modes. Consequently, 1 –3, which are isostructural, have a 3-D 4-connected topology with (4 2 .8 4 ) Schläfli symbol.4 has a 3-D (4, 6)-topology, with (4 3 .6 3 )2 (4 6 .6 6 .8 3 ) Schläfli symbol. Both1 and2 reveal weak antiferromagnetic behavior. In addition, 3 and4 exhibit purple and blue emission bands, respectively. These results indicate that 3, 3′-H2 dbpt is an excellent multi-connection linker to construct MOFs with interesting structures and properties. Abstract :
