Abstract

AbstractThe β‐diketonate derivative ligand [H2L = 6‐(3‐hydroxy‐1‐oxo‐3‐pyrryl‐2‐propen‐1‐yl)‐2‐pyridinecarboxylic acid] and its zinc(II) coordination complexes, [Zn(H2L)Cl2]·(EtOH)(H2O) (1) and [Zn4(L)4(H2O)2]·5H2O (2), were prepared and characterized by elemental analysis, IR and NMR spectroscopy, and single‐crystal X‐ray diffraction. Complex 1 is a mononuclear structure. Complex 2 is a [2 × 2] grid tetranuclear structure. The luminescent properties of the free ligand H2L and complexes 1 and 2 in methanol solution were studied.
