A new trinuclear zinc(II) complex possessing five- and six-coordinated central ions and its photoluminescent property

A aromatic Schiff base ligand, N, N′-bis((4, 4′-diethylamino)salicylidene)-1, 2-phenylenediamine (H2L), and its trinuclear zinc(II) complex, Zn3L2(CH3COO)2, were synthesized. The X-ray crystal structure of the complex reveals that two zinc ions show the coordination number of five and the third one has the coordination number of six. The complex exhibits blue-green emission as the result of the fluorescence from the intraligand emission excited state.
