Structural, spectroscopic and electronic properties of a family of face-shared bi-octahedral Ru25+/6+ complexes with a bridging 2,5-di(2-pyridyl)pyrrolide ligand

Herein, we found that nitrogen donor dpp−ligand is flexible and provides a platform for aggregation of Ru2+ and/or Ru3+ to give a new type of face-sharing bi-octahedra Ru25+ and Ru26+ dimer featuring of distinct metal–metal bond bond between two ruthenium centres.
