Abstract: The title complex[Ag2(HL)(NO3)2]n (1) (HL=1-(3-ethylpyrazin-2-yl)ethylidene-4-phenylsemicarbazide) has been synthesized and characterized by single crystal X-ray diffraction, elemental analysis and IR spectroscopy. X-ray diffraction analysis results show that in 1, HL acts as a neutral tetradentate ligand to connect with two Ag(I) centers, one of which adopts a distorted square pyramid coordination geometry involving one HL ligand with ON2 donor set (carbonyl O, imine N, and pyrazine N1 atoms) and two monodentate nitrate anions; while the other one is four-coordinated with one monodentate nitrate anion, one bidentate nitrate anion and pyrazine N4 atom, thus giving a planar square coordination geometry. Adjacent Ag(I) ions are further connected by bridged nitrate anions to form a 2D framework; Moreover, the fluorescence spectra indicate that the interaction of the complex 1 with DNA is stronger than that of the ligand HL. |
