Tetranuclear Cu(II) complex with octaazamacrocycle and bridging bicyclic dicarboxylato ligands

A new tetranuclear copper(II) complex of the formula [Cu4L(tpmc)2](ClO4)6·4NaClO4 (tpmc = N,N,N,N-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane; L = endo-bicyclo[2.2.1]-hept-5-en-2,3-cis-dicarboxylate dianion) has been isolated. The complex was characterized by elemental analysis, magn...

Description
Summary:A new tetranuclear copper(II) complex of the formula [Cu4L(tpmc)2](ClO4)6·4NaClO4 (tpmc = N,N,N,N-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane; L = endo-bicyclo[2.2.1]-hept-5-en-2,3-cis-dicarboxylate dianion) has been isolated. The complex was characterized by elemental analysis, magnetic and conductometric measurements, electronic and IR spectroscopy and cyclic voltammetry (CV). This is one of the rare cases when a tetranuclear complex with tpmc is formed, with the bulky bicyclic dicarboxylate as the bridging ligand between two tpmc units in which two copper(II) ions are coordinated in the exo position.
