چکیده

A new kind of N-ligand based on heptazine derivatives is presented. A trinuclear Cu(II) complex, [(L)2CuCl3](ClO4)3·3CH2Cl2 (L = 2,4,6-tris(di-2-pyridylamino)heptazine), utilizing a pyridine derivative of heptazine has been synthesized and characterized avoiding the inherent solubility problems of heptazine compounds. Thus, this work opens the application of such ligands either in supramolecular chemistry as a larger ligand of the widely used s-triazine derivatives or to provide molecular systems for photocatalysis as heptazine is the fundamental unit of the very promising g-C3N4 2D compound.
