| مستخلص: |
Two new complexes, [Co(MPAFA)3](ClO4)2 (1) and [Ni(MPAFA)3](NO3)2·2H2O (2), of an 'NN' bidentate Schiff-base ligand, N-(furan-2-ylmethyl)-1-(5-methyl-1H-pyrazol-3-yl)methanimine (MPAFA), have been synthesized and characterized by physicochemical and spectral methods such as elemental analyses, conductance, IR, UV-Vis, and emission spectra. In both complexes, three ligands coordinate with a metal ion to form 1:3 complexes. Both 1 and 2 are distorted octahedral and cationic, behaving as 1:2 electrolytes. IR spectra showed that each of the ligands coordinates via the pyrazolyl tertiary nitrogen and the azomethine nitrogen atoms. Single crystal X-ray studies confirmed CoN6 and NiN6 coordination for 1 and 2, respectively, and showed that both complexes exhibit π...π stacking and various hydrogen bonding interactions. Both 1 and 2 are fluorescent and participate in DNA binding with calf thymus DNA (CT-DNA) via groove binding. [ABSTRACT FROM AUTHOR] |
