“…In the IR spectrum of 2, the characteristic band of -COOH near 1700 cm −1 is not observed, but we observed the characteristic strong absorption bands in 1545-1514 cm −1 and 1395-1380 cm −1 which are assigned to the asymmetric and symmetric stretching vibrations of the carboxylate groups, respectively. 11 The luminescent spectra of complexes 1 and 2 as well as that of the free ligand H 3 L were measured in the solid state at room temperature (Fig. 6).…”

“…The lattice water molecules are stabilized by hydrogen bonding interactions. Compound 4 was reported by Wang et al12 In their paper, this compound crystallizes in the monoclinic P 2 1 / c space group, having an uncommon SO 4 2– anion morphology and scarce S–O bond lengths (1.702 Å). However, careful analysis and refinement pointed out that compound 4 has Pc space group, with acceptable SO 4 2– anion morphology and S–O bond lengths.…”

X-ray analysis revealed that the four coordination compounds have different structures: Compound 1 is a three dimensional supermolecular structure joined by hydrogen bonding interactions based upon dinuclear units. Compound 2 is a three dimensional

The Eu III ion is coordinated by nine O atoms from two H 2 bdc ligands, two sulfate anions and three water molecules, displaying a bicapped trigonal prismatic geometry. The carboxylate groups of the H 2 bdc ligands and the sulfate anions link the Eu III ions, forming a chain along [010]. These chains are further connected by N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds and -interactions between the imidazole and benzene rings [centroid-centroid distances = 3.997 (4), 3.829 (4) and 3.573 (4) Å ] into a three-dimensional supramolecular network.
