Název v původním jazyce

Copper(II) complexes of tridentate selenobisphenolate ligand in mixed ligand environments: Synthesis, crystal structure, EPR and electrochemical studies

Popis výsledku v původním jazyce

A series of square-pyramidal copper(II) complexes, [Cu(L-Se)(N-N)] (H2LSe = seleno-bisphenolate; N-N = bipyridyl, phenanthroline or N,N-dimethylethylenediamine) have been synthesized and characterized by elemental analyses, magnetic measurements, IR, EPR, and electronic spectral studies. Single crystal X-ray structures of [Cu(L-Se)(bpy)]center dot H2O (2), [Cu(L-Se)(phen)]. CH2Cl2 (3) and [Cu(L-Se)(N,N-Me(2)en)] (4) showed that all the complexes have approximately square-pyramidal geometry. In complexes2 and 3, the square plane is occupied by O(1) O(2) N(1) and N(2) and the apical position by Se atom of L(Se 2-)ligand. The asymmetric unit of complex 4 contains two crystallographically independent discrete molecules A and B with CuN2OSe chromophore comprising the square plane and the axial position being occupied by another phenolate oxygen atom. Complexes 2, 3 and 4 are found to be paramagnetic. Both the complexes 2 and 4 show three reduction processes: (a) a quasi-reversible reductio
