title: Multidentate ligands for the synthesis of multimetallic complexes. 2. Formation of a planar Cu4OH motif.
abstract: The reaction of the multidentate Schiff base species TrenSal, TrenBrSal, and TEtSal with copper acetate is reported. The heptadentate ligands generate a tetrametallic L(2)Cu(4)OH motif that contains an internalized hydroxide anion. In contrast, the hexadentate TEtSal ligand is found to form an open trimetallic motif. The importance of L(2)Cu(4)OH to the family of copper complexes with an endohedral hydroxide anion is discussed. [(TrenBrSal)(2)Cu(4)OH][OAc] is analyzed by temperature-dependent magnetic measurements.
