| Abstract: A bis-N,O-bidentate Schiff-base ligand H2L, named as 4,4′,6,6′-tetrabromo-2,2′-(1,2-phenylenebis(nitrilomethylidyne))diphenol and condensed from 3,5-dibromo-2-hydroxybenzaldehyde and 1,2-phenylenediamine, and its mononuclear five-coordinate zinc(Ⅱ) and four-coordinate nickel(Ⅱ) complexes [ZnL(H2O)] and [NiL] (1 and 2) have been synthesized and structurally and spectrally characterized. Detailed comparisons were carried out on the differences in their molecular structures and supramolecular interactions, 1H NMR, UV-Vis and fluorescence spectra before and after metal-ion complexation. CCDC: 763677, H2L; 763678, 1; 763679, 2. | |||||||||
