Sažetak
Ternary coordination compounds of copper(II) with amino acids and chelating heterocyclic bases have been investigated for several decades due to their pronounced antitumor activity [1]. These compounds are interesting in crystal engineering since they have the ability to form predictive supramolecular motifs through non-covalent interactions, such as π-interactions and hydrogen bonds. However, systematic research of different solvatomorphs has been reported only in a few research articles [2–4]. Our group is also interested in exploring the properties of such compounds, i.e.stability of crystals in the solid state and their ability to absorb water molecules or other solvents [2, 3]. As a part of our research, we report the solution- based and mechanochemical syntheses and crystal structures of five ternary coordination compounds of copper(II), 1, 10- phenanthroline (phen) and glycine (HGly) with water and methanol as solvent. Different crystallization experiments with a very small difference in the amount of water (less than 1% of volume fraction) resulted in different solvatomorphs crystallizing. Water content in reactants was crucial for the formation of certain solvatomorphs in mechanochemical syntheses. All compounds contain crystallization solvent molecules forming pockets and/or infinite channels (1D or 2D). Stability and solid-state transformations in atmospheres of methanol vapors or different relative humidity were also investigated (Figure 1).
