Supramolecular diversity in copper(II) complexes with L-homoserine/L-serine with heterocyclic bases
Copper(II) complexes with heterocyclic bases and amino acids have been in focus of research in the past several decades due to their versatile properties. These type of complexes are already used in anticancer therapy as they show pronounced antiproliferative activity [1, 2]. Moreover, copper(II) complexes with amino acids are capable of forming a vast variety of supramolecular motifs [3], which makes them interesting compounds not only in crystal engineering, but also in catalysis, molecular recognition, and investigation of metal-protein interactions. In our recent research we have focused on the investigation of (amino acidato)copper(II) complexes and manipulation of their crystal structures in the solid state [2]. In this research we report two new structures of copper(II) complexes with the L-homoserinate ion (hser) and either 1, 10-phenantroline (phen) or 2, 2’-bipyridine (bpy): [Cu(μ-hser)(H2O) (bpy)]2SO4·4H2O (1) and [Cu(μ-hser)(H2O)(bpy)] [Cu(μ-hser)(bpy)]SO4·6H2O (2). Interestingly, no crystal structures of homoserine complexes have been deposited in the Cambridge Structural Database so far [3]. Both complexes crystallize as 1D coordination polymers interconnected by π- interactions and hydrogen bonds, producing 3D supramolecular frameworks. 1 crystallizes in the monoclinic space group P 21, while 2 crystallizes in the triclinic space group P 1. A comparative study of copper(II) complexes with L-serine/L- homoserine and 2, 2’- bipyridine/1, 10- phenantroline will be presented, including the structural characteristics and chemical properties. It was shown that subtle changes in synthetic or atmospheric conditions can make a significant difference in the crystal packing.
