Sažetak
Metal–organic frameworks are porous polymeric materials built from metal ions or clusters linked by organic ligands [1, 2]. They have attracted a high interest due to their specific properties (porosity, stability, low density, large specific surface area, susceptibility to functionalization) [3, 4] and potential for application in various fields, such as gas storage [2], water harvesting [5], air purification [2], drug delivery [4] and many others. Great significance is given to the design of threedimensional, highly porous structures with predictable topologies and properties controlled mainly by the chemical nature of the individual components, but also by other factors such as temperature, type of solvent and pH-value [1, 2]. In this work we report synthesis and structural characterization of four new copper(II) coordination polymers with N-methylglycinate (MeGly) and 4, 4’-bipyridine (4, 4’-bpy). Three of them are 3D coordination polymers, while the fourth compound is 1D coordination polymer. The topological analysis revealed that one of the compounds has completely new topological type, which has not been stored in the Reticular Chemistry Structure Resource database so far. We investigated the influence of crystallization conditions on the crystal packing, as well as on the shape and size of channels. Channels in these metal–organic frameworks occupy from 29.2% to 61.8% of the unit cell volume. For one of reported compounds, stability at different relative atmospheric humidity and biological activity against human hepatocellular carcinoma cells and acute monocyte leukemia cells in vitro were also tested.
