Structures and Fluorescent Properties of Cadmium(II) Complexes with 1D and 2D Structures Based on Tridentate Benzimidazole Ligands
The cadmium(II) complexes [CdL1(m-nba)2] (1), [CdL1(p-nba)2]¡¤C2H5OH (2), [CdL2(p-nba)2]¡¤CH3OH (3), and [CdL2(p-nbat)2] (4) containing the ligands L1 and L2 [L1 = 2,6-bis(benzimidazol-2-yl)pyridine, L2 = bis(2-benzimidazolylmethyl)amine] were synthesized and characterized (m-nba, p-nba, and p-nbat are the anions of p-nitrobenzoic acid, m-nitrobenzoic acid, and p-nitrobenzeneacetic acid, respectively). The complexes were investigated by X-ray single crystal diffraction, elemental analysis as well as IR and fluorescence spectroscopy. Compounds 1-3 contain a distorted pentagonal bipyramidal coordination sphere with CdII coordinated by two carboxylate ligands in bidentate-chelating mode, whereas complex 4 exhibits a distorted octahedral arrangement with one carboxylate ligand in bidentate-chelating and the other in monodentate coordination mode. 1 and 2 form a 1D chain interplayed by hydrogen bonding and strong pi-pi stacking interactions. 3 and 4 vary from 1D chain into 2D single-layer and double-layer networks because of more extensive hydrogen bonding interactions. The complexes show emission maxima in the blue region in the solid state and emission bands are red-shifted compared to those of the free ligands.
