Abstract: In this study, two new isomorphic binuclear compounds, [Ln(µ-NAP)4(NAP)2(phen)2] · H2O (1) and (2) (Ln = Eu, Tb, NAP = N-acetyl-N-phenylglycinate; phen = 1,10-phenanthroline), have been synthesized and characterized by infrared spectroscopy, elemental analysis, and X-ray crystallography. These compounds crystallize in a triclinic form with space group with a = 11.7519(11), b = 13.4293(12), c = 14.0686(13) Å, V = 1992.7(3) Å3, and Z = 1. Single-crystal X-ray structural analysis reveals that 1 is binuclear, assembled into a 3-D supramolecular network with self-complementary double hydrogen-bonding interactions and aromatic π-π interactions. Fluorescence properties of 1 and 2 are also discussed.
