X-Ray absorption spectroscopic studies of ruthenium–octaethylporphyrin dimers
Abstract
A series of metal–metal bonded dimeric ruthenium porphyrin complexes have been characterized by means of X-ray absorption spectroscopy, Ru–Ru bond lengths for Ru2.5+ and Ru3+ complexes having been determined by EXAFS to be 2.29 and 2.22 Å, respectively; electronic configurations also have been confirmed by X-ray absorption near edge spectroscopy.
