Abstract

The ligand of 2-(4-pyridyl)-4-methylthiazole-5-carboxylic acid (HL) has been employed to react with Cd(NO3)2·6H2O or a 50% aqueous solution of Mn(NO3)2, to yield two isomorphous three-dimensional (3D) coordination compounds, [Cd(L)2](H2O)4(DMF) (1) and [Mn(L)2](H2O)3(DMF) (2). The structures and properties of the compounds have been characterized by several techniques. Both compounds are three-dimensional (3D) neutral frameworks possessing permanent pores that give rise to straight one-dimensional channels. Compound 1 displays adsorption selectivity for CO2, while the low pressure sorption of H2, N2, CH4, CO, O2 at 298 K are negligible; Compound 2 shows weak anti-ferromagnetic coupling between the magnetic centres.
