Synthesis of new hybrid materials, structural characterization, and study of their electrochemical properties

Abstract

In this work, two new single-crystals hybrid ionic materials tris(2,4,6-triamino-1,3,5- triazinium) monodrogenphosphate dihydrogenphosphate tetrahydrate (3C3H7N6 +.HPO4 2-.H2PO4 -.4H2O) and 2,4,6-triamino-1,3,5-triazinium perchlorate monohydrate (C3H8 N6 + .ClO4 - .H2O) were synthesized, their structures were affined by single-crystal X-ray diffraction the 3Dsupramolecular structure has been investigated basing on the SXRD data. Moreover, UVvisible and FT-IR spectroscopy have been used to establish optical and vibrational properties .The study of the thermal decomposition of these hybrid materials was also occurred by TGA/DTG techniques. These hybrids were examined as corrosion inhibitors using electrochemical methods. The electrochemical properties were studied by cyclic voltammetry. These inhibitors are effectively adsorbed by a chemisorption process to the steel surface. The adsorption of these compounds follows the Langmuir isotherm in the studied medium. The results show that these compounds have good reactivity and high inhibition efficiency.
