“…Thus the carboxylates coordinate to the metal as bidentate ligands via the carboxylate groups [16]. The absence of Table 2 Selected bond lengths (Å ) and bond angles (deg) for 1 [17]. In addition, X-ray diffraction analysis further indicates the bidentate coordination manners of carboxylate groups and the deprotonation of H 2 C 2 O 4 ligands.…”

A new Zn(II) coordination polymer based on oxalic acid and 1,4-bis(imidazol-1-ylmethyl)benzene (bix), namely, [Zn(C 2 O 4 )(bix)] n (1), has been successfully synthesized under hydrothermal conditions. Its structure has been determined by single crystal X-ray diffraction analysis, elemental analyses and IR spectroscopy. Compound 1 shows a two-dimensional (2D) layer structure. The intermolecular C-HÁÁÁO interactions extend the compound 1 into 3D supramolecular architectures and play an important role in stabilizing compound 1. In addition, the luminescent property of the compound has also been investigated in solid state at room temperature.

“…The enhancement of fluorescence may be attributed to ligand chelation to the metal center, which presumably increases the rigidity of the ligand and decreases the loss of energy by non-radiation decay. Additionally, fluorescence behavior is closely related to the local environment around metal ions [9].…”

“…These emissions are neither metal-to-ligand charge transfer (MLCT) nor ligand-to-metal charge transfer (LMCT) in nature since the Zn 2+ or Cd 2+ ions are difficult to oxidize or to reduce due to their d 10 configuration which can probably be assigned to the intraligand (-*) fluorescent emission [29]. It is clear that hypsochromic shift of emission occurs in 1, 2 and 3, which is probably due to that the coordination of the 1,8-nap ligand breaks the coplanar effect of the naphthalene-1,8-dicarboxylic anhydride molecule, because photoluminescence behavior is closely associated with the local enviroment around metal ions [30].…”

Three d 10 tetranuclear complexes, [Cd 4 (1, 4 (2,2′-bipy) 4 (H 2 O) 8 ]·6H 2 O (1,8-nap = naphthalene-1,8-dicarboxylate and 2,2′-bipy = 2,2′-bipyridine) (1), [Cd 4 (1,8-nap) 4 (2,2′-bipy) 4 (H 2 O) 8 ]·6H 2 O (2) and [Zn 4 (1,8-nap) 4 (2,2′-bipy) 4 (H 2 O) 4 ]·2H 2 O (3), have been synthesized under hydrothermal conditions and characterized by elemental analyses, IR and X-ray diffraction techniques.Complexes 1 and 2 are isomers showing one-dimensional ribbon-like structures connected by O−H···O hydrogen bonds, and the one-dimensional ribbons are further linked into the three-dimensional network by - stacking. In complex 3, the intramolecular OH···O hydrogen bonds just exist in the inner of the single molecule ring to consolidate its structure, and the single molecules are further linked into a two-dimensional layer structure by the - stacking interactions. The luminescent properties reveal that all the complexes display luminescent properties in the violet region. crystal structure, d 10 metal, naphthalene-1,8-dicarboxylic anhydride, - stacking, hydrogen bond, violet luminescence
