Synthesis, Characterization and Thermal Study of Some New Metal Ions Complexes with a New Azo ۲-((۲-(۱H-Indol-۲-yl)ethyl)diazinyl)-۵-aminophenol

This research includes the preparation of a new azo ۲-((۲-(۱H-indol-۲-yl)ethyl)diazinyl)-۵-aminophenol, in which the diazonium salt of ۲(۱H– Indole–۳yl)- ethylamine reacts with a compound ۳-aminophenol, and complexes have been prepared with the ions of  Ni (II), Pd(II), Pt(IV), and Au(III). The characteristics of compounds include F.A.A, (C. H .N and O), ۱H & ۱۳C-NMR, IR, LC-Mass , UV-Vis spectral, DSC/TGA curve, the measurements of magnetic, and molar conductance. Each complex has an amount of [۱:۱] [M:L] and does not contain electrolytes. Based on the obtained results, molecular structural and geometry have been octahedral geometry suggest of Pt(IV) complex and tetrahedral of Ni (II)complex, the square planar of both Pd(II) and Au(III) complexes.
