| Abstract: | Complexes with formula [Cu(BBES)X2].nH2O have been synthesized where BBES is a tridentate ligand containing bis-benzimidazolyl as pendant coordinating group and X is an exogenous anionic ligand (X = HCOO- , CH3COO- ,Cl-, Br-, NO-3). Solution EPR spectroscopy on these complexes reveals that the ground state in these copper (II) complexes comprises d x2-y2 orbital. Cyclic voltammetric studies reveal that E1/2for Cu(II)/Cu(I) couple shifts cathodically with HCOO- as the anionic ligand, implying that binding of this anion stabilizes the Cu (II) state whereas E1/2 , data for NCS-indicates that this anion destabilizes Cu(II) state. Copper (I) complex has also been synthesised in the presence of hydroquinone which shows a well-resolved NMR spectrum in the range 0-10 ppm. |
