Two chromium complexes [CrO2 (C8H5O4) (H2O) 3] and [CrO2 (C8H5O4) (H2O) 3]. H2O was prepared by reducing CrO3 with ethanol in the presence of phthalic acid (H2pht) at room temperature to give a solution containing the monomeric and dimeric Cr (III) complexes. The H2pht / Cr molar ratios in 1: 1 and 1: 2 solutions are indefinitely stable against precipitation. These analyzes are performed using elemental (C and H), ICP-OES (for Cr%), UV-Vis, FTIR, 1HNMR, and fast atom bombardment (FAB) mass spectrometry, and DSCs are thermally behaved. I investigated. The results showed that the complex formed was probably monomeric. It was found that changing the reaction conditions only slowed the rate of reaction and complex formation, not the properties of the product. The kinetics and instability of the complex can be predicted from the DSC.
