摘要:
Compounds [Re(CO)(3)X(R-DAB)], X = Cl, Br, CN, NCS and R-DAB = RN=CH-CH=NR (R = tert-butyl) were obtained, structurally characterized, and studied with regard to their oxidation and reduction behavior using cyclic voltammetry, EPR, IR and UV-vis-NIR spectroelectrochemistry. Whereas the halide compounds exhibit more reversible oxidation processes, the pseudohalide complexes display reversible one-electron reduction but irreversible oxidation. DFT and TD-DFT calculations were employed to confirm the experimentally derived electronic structures and spectral properties. (c) 2013 Elsevier B.V. All rights reserved.
