Formula: C5H7N3This research focused ontransition metal complex fluorescent Schiff base analysis. The article conveys some information:
Synthesis and characterization two Schiff bases[L1] (N2Z,N6Z)-N2,N6-bis(4-((E)-anthracen-9-ylmethyleneamino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-ylidene)pyridine-2,6-diamine Synthesis via reaction of 2,6-diaminopyridine, 4-aminoantipyrine and 9-anthracenecarboxaldehyde with mole ratio (1:2:2) resp. two steps. And [L2] (N1Z,N2Z)-N1,N2-bis(4-((E)-anthracen-9-ylmethyleneamino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-ylidene)-4-methylbenzene-1,2-diamine Synthesis from reaction of o-phenylendiamine, 4-aminoantipyrine and 9-anthracenecarboxaldehyde with mole ratio (1:2:2) resp. two steps. A new series of transition metal complexes of Mn(II), Co(II), Ca(II), Cd(II), Zn(II) and pd(II) were synthesized. The structural features were derived from their elemental analyses, IR, UV-visible spectroscopy, 1HNMR, 13CNMR spectroscopy, thermal gravimetric analyses spectral, magnetic susceptibility measurement, chloride content and conductivity measurements. The electronic spectral data and magnetic measurements indicate that the complexes exhibit octahedral geometry around Ca(II), Mn(II), Cd(II), Co(II), Zn(II) while Square planer geometry around Pd(II). In addition to this study using 2,6-Diaminopyridine, there are many other studies that have used 2,6-Diaminopyridine(cas: 141-86-6Formula: C5H7N3) was used in this study.
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Formula: C5H7N3
