Under the hydrothermal conditions, two new 4,4′-oxydiphthalhydrazidate-containing compounds [Zn2(odpth)2(phen)2]·H2O 1 and [In(odpth)(ox)(phen)] 2 (odpth = 4,4′-oxydiphthalhydrazidate, phen = 1,10-phenanthroline, ox = oxalate), were obtained. Note that odpth ligand was derived from the hydrothermal in situ acylation reaction between 4,4′-oxydiphthalic acid (odpha) with N2H4⋅H2O. In compound 1, the odpth ligands exhibit a μ2-bridging mode, which link Zn(II) centers into a 1-D chained structure with ancillary phen molecules. Interestingly, in compound 2, the ox ligands exhibit a μ2-bridging mode, which link In(III) centers into a different 1-D chained structure with ancillary odpth and phen molecules. Although they are only 1-D chained coordination polymers, they all further self-assemble into the interesting supramolecular networks via π⋯π stacking or hydrogen-bonded interactions. The photoluminescence analyses indicate that the compounds in the different states (in the solid state or in aqueous solution) may exhibit different emission behaviors.
