During the formation of the complex, one of the salicylaldimine groups of one of the molecules of the H<sub>2</sub>L ligand hydrolyzed to form an asymmetrical ligand with an amino group leading to the molecule (2-((2-aminophenylimino)methyl)phenol (HL’). The complex was formulated as {[Cu(L)].[Cu<sub>2</sub>(L)(L’)]}.(ClO<sub>4</sub>). The structure of the complex was solved by single crystal X-ray crystallography. In the mononuclear unit, the Cu<sup>2+</sup> atom is coordinated by one dideprotonated&nbsp; molecule of the ligand acting in tetradentate fashion. In the&nbsp; dinuclear unit, one the Cu<sup>2+</sup> atom is coordinated by one dideprotonated&nbsp; molecule of the ligand acting in tetradentate fashion and the other Cu<sup>2+</sup> is coordinated by the monodeprotonated (2-((2-aminophenylimino)methyl)phenol (HL’) acting in tridentate fashion. The two Cu<sup>2+</sup> are bridged by the two phenoxo oxygen atoms of the dideprotonated&nbsp; molecule of the ligand. The complex crystallizes in the triclinic space group <em>P</em>ī with the following parameters: a = 13.8864 (3) Å, b = 14.2078 (4) Å, c = 14.5007 (4)) Å, α = 64.593 (3), β = 71.353 (2), γ = 71.707 (2)°, V = 2395.80 (13) Å<sup>3</sup>, Z = 2, R<sub>1</sub> = 0.037, wR<sub>2</sub> = 0.041. The supramolecular structures are consolidated by multiple hydrogen bonds.</p&gt;}, number={1}, journal={Earthline Journal of Chemical Sciences}, author={Diouf, Ngoné and Thiam, Ibrahima Elhadj and Sylla-Gueye, Rokhaya and Retailleau, Pascal and Gaye, Mohamed}, year={2022}, month={Mar.}, pages={35-52} }
