Preparation and characterization of new in(iii), re(iii), and re(v) complexes with thenoyltrifluoroacetone and some bidentate heterocyclic ligands

Abstract

All chemical used were of analytical grade and were used without further purification. IR spectra were recorded in KBr pellets on a Perkin Elmer FT-IR spectrometer. "Spectrum 1000". UV-Vis spectra in ethanolic solutions were recorded on a Cecil 599 spectrophotometer using 1 cm matched silica cells. 'H and , 3 C NMR spectra were measured in DMSO-d6 as solvent on a JEOL NMR 400 MHZ spectrometer. Elemental analyses were carried out on a Perkin Elmer 2400 CHNSO elemental analyzer. Iidium contents in the investigated indium complexes were determined by the analytical laboratory at SABIC (R&D) (Saudi Arabia). TG measurements were carried out using a Netzsch STA-429 thermal analyzer. The weight loss was measured from ambient temperature up to 700 °C'at a heating rate of 10 °C/min. X-ray diffraction patterns of the complexes were recorded using a XRD 5000 Siemens diffractometer with Cu-target.
