  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.

  Four coordination polymers, [Zn(o-bdc)(bth)0.5(H2O)] n (1), [Cd(o-bdc)(bth)0.5(H2O)] n (2), [Zn(m-bdc)(bth)] n (3), and [Cd(p-bdc)(bth) · (H2O)2] n (4) (where o-bdc = 1,2-benzenedicarboxylate, m-bdc = 1,3-benzenedicarboxylate, p-bdc = 1,4-benzenedicarboxylate, and bth = 1,6-bis(triazol)hexane), have been hydrothermally synthesized and structurally characterized. Both 1 and 2 are isostructural, featuring two binodal architectures: (63)(65.8) topology in terms of o-bdc and ZnII/CdII as three- and four-connected nodes. Complex 3 shows a 2-D (4,4) network with the Zn … Zn … Zn angle of 57.84°, whereas 4 exhibits planar 2-D (4,4) network. These 2-D networks of 3 and 4 are extended by supramolecular interactions, such as CH … π/π-π stacking and hydrogen-bonding into 3-D architecture. A structural comparison of these complexes demonstrates that the dicarboxylate building blocks with different dispositions of the carboxyl site play a key role in governing the coordination motifs as well as 3-D supramolecular lattices. Solid-state properties such as photoluminescence and thermal stabilities of 14 have also been studied.
