Complexes of Zn (II) containing (o-)/(p-) carboxylato phenyl azo pentane 2, 4-dione and 2, 2′ bipyridine as ligands: Synthesis, characterization, colorimetric and …
Azo–enol based ligands 2-[N′-(1-acetyl-2-oxo-propylidene) hydrazino]-benzoic acid (L1H2) and 4-[N′-(1 acetyl-2 oxo-propylidene)-hydrazino]-benzoic acid (L2H2) and their complexes [Zn (L1H) 2 (bpy)](1) and [Zn (L2H) 2 (bpy)](2)(where bpy= 2, 2′-bipyridine) have been synthesized and characterized using elemental analyses, spectral (FT-IR, 1H NMR, 13C NMR, electronic absorption), emission and single-crystal X-ray diffraction ...
