Complexes [CrO₂ (C₈H₅O₄) (H₂O) ₃]  and [CrO₂ (C₈H₅O₄) (H₂O) ₃] .H₂O were prepared by reduction of CrO₃ at room temperature by ethanol in the presence of phthalic acid (H₂pht) yield solution that contains monomeric and dimeric Cr (III) complexes. A solution H₂pht/Cr molar ratio of 1:1 and 1:2 is indefinitely stable towards precipitation. Their analysis were done by using elemental (C and H), ICP-OES (for Cr %), UV-Vis, FTIR, ¹HNMR and Fast Atomic Bombardment (FAB) Mass spectrometry, whereas thermal behaviour was investigated by DSC.
