The bond a ngles around the Ni(1) WebSalen was formed by a condensation reaction between two molecules of salicylaldehyde and one of ethylenediamine, hence the name salen. Salen is a tetradentate chelating agent, and holds the cobalt atoms in place during the synthesis of Co (salen), which is itself a tetradentate ligand. fFigure 1.

WebApr 10, 2013 · Synthesis of the Metal Complexes The metal complexes were isolated as follows: metal acetate (2 mmol) dissolved in 10 mL of methanol was added dropwise to a 10 mL methanolic solution of the ligand (2 mmol). The mixture was kept under reflux for 1-2 hours. The solution thus obtained gave the compound on concentration and cooling. simpsons episode free online

H2salen may be synthesized by the condensation of ethylenediamine and salicylaldehyde. Complexes of salen with metal cations may be made without isolating it from the reaction mixture. This is possible because the stability constant for the formation of the metal complexes are very high, due to the … See more Salen refers to a tetradentate C2-symmetric ligand synthesized from salicylaldehyde (sal) and ethylenediamine (en). It may also refer to a class of compounds, which are structurally related to the classical salen ligand, primarily bis- See more • Metal salen complexes • Bisthiosemicarbazones, a structurally related class of C2-symmetric imine based ligands See more A class of tetradentate ligands with the generic name acacen are obtained by the condensation of derivatives of acetylacetone and ethylenediamine.
