Abstract |
Copper(II) complex, {[Cu(L)(H2O)2][Cu2(L)2(μ-btc)]∙2ClO4∙6H2O∙1.454CH3CN (1) (L = tetraazamacrocycle, btc = 1,2,4,5-benzenetetracarboxylate ion) was prepared by the reaction of [Cu(L)](ClO4)2 and btcH4 in DMF/H2O/CH3CN/NEt3. The complex 1 was characterized by EA, IR and TGA techniques. In addition, molecular structure was determined by single crystal X-ray diffraction methods. In 1, two different copper(II) coordination geometries, a five-coordinate square pyramid as well as an axially elongated six-coordinate octahedron, are observed. The btc ligand bridges two copper(II) macrocycles to form a dimer where all the hydrogen atoms of btcH4 were deprotonated, forming a complex dianion. Additional copper(II) macrocycle involves in (1) in which two aqua ligands interact with central metal ion weakly, resulting in the formation of complex dication. Thus, the whole complex (1) is charge balanced. Details of the structural properties will be discussed in this presentation. |
