A trimetallic zinc(II) complex and its catecholase activity

Synthesis, Electronic, Magnetic and Structural Characterization of New Trinuclear Mixed‐Valence CoIII‐CoII‐CoIII Complex.

“…Indeed, the pH‐controlled protonation or deprotonation of the phenolic groups gives the possibility to obtain compounds with different numbers of metal centres and coordination geometries, giving rise to synthesis of homometallic or heterometallic complexes . These compounds are also of interest for their catalytic properties and as models of biological systems …”

Hexanuclear Zn(II) and Mononuclear Cu(II) Complexes containing imino phenol ligands: Exploitation of their Catalytic and Biological Perspectives

“…Since dicopper(II) units are the centers of activity in catechol oxidase, the preferred choice to several research groups is dinuclear Cu(II) systems as catalysts for catechol oxidation reaction . In contrast with various dinuclear Cu(II) systems, a few mononuclear Cu(II) complexes and Zn(II) based compounds bearing diversified ligands with N/O donors were reported in the literature . Thus, there is an excellent scope of exploitation of such mononuclear Cu (II) units and hexanuclear Zn (II) compound as catalysts towards the conversion of 3,5‐di‐ tert ‐butylcatechol (3,5‐DTBC) to 3,5‐di‐ tert ‐butylquinone (3,5‐DTBQ).…”

The Crystal Structure and Physicochemical Properties of New Complexes Containing a CuII-LnIII-CuII Core

“…By analyzing the coordination abilities of Schiff bases in terms of the possibility of attaching single metal ions, it can be observed that most Schiff bases formed in the reaction of diamines and their derivatives with o-hydroxyaromatic aldehydes/ketones coordinate a 3d ion in the tetradentate cavity of N 2 O 2 . It is possible to obtain mono- [12,13], di- [14][15][16][17][18], tri- [19,20], tetra- [16,21], and even hexanuclear [22] complexes (Figure 2). In the homodinuclear compounds, the metal:ligand ratio can be 2:1, 2:2, 3:2.…”

“…In the second case, the central ions most often connect to the symmetric units of the ligand through the deprotonated hydroxyl groups of the Schiff base. In the homotrinuclear complexes, the central ions are arranged linearly and are alternately connected to each other by a bridging element, which may be an acetate ion, for example [19,20]. [12][13][14][15][16][17][18][19][20]23].…”
