Synthesis, crystal structure and electronic properties of [3.3]metaparacyclophane-bridged bimetallic ruthenium alkynyl complexes
摘要:
A series of [3,3] metaparacyclophanes bridged bimetallic ruthenium complexes have been designed, synthesized and characterized. H-1 NMR and X-ray crystal structure studies revealed that there are prominent intramolecular edge-to-face interaction in these diruthenium complexes, both in the solution and solid states. Electrochemical analyses indicated that the electron-withdrawing substituent groups (-CN, -NO2) can enhance the thermodynamic stability of corresponding mixed-valence species. (C) 2015 Elsevier B.V.
