Abstract or Keywords
Three new complexes of the type Mn(NN)(CO)(3)Br have been synthesized, where NN = 5-substituted-1,10-phenanthroline. The novel compounds have been characterized by H-1 NMR, FTIR, CV, HRMS, and UV/Vis, as well as X-ray crystallography in one case. The known NN = phenanthroline compound, and four analogous Re(I) compounds are also presented; their photophysical and electrochemical properties are discussed. A correlation is apparent between the MLCT absorbance bands and the electrochemical reduction of both the Re and Mn series of compounds. (C) 2014 Elsevier B.V. All rights reserved.
