Electronic Structure and Spectroscopic Properties of Copper Catecholate Complexes with Interligand Charge Transfer Behavior.
Inorganica Chimica Acta 204 (2), pp. 189-193.
The structural and spectroscopic properties of copper catecholate complexes with nitrogen ligands of the α- diimine type are studied by qualitative MO considerations. The characteristic feature of these donor acceptor systems is an interligand charge-transfer from the catecholate donor to the α-diimine acceptor site. The dependence of the interligand charge-transfer absorption band on the energies of the acceptor and the donor levels as well as on the solvent polarity is discussed.
