Evidence for Multicenter Bonding in Dianionic Tetracyanoethylene Dimers by Raman Spectroscopy

Long CC bonds: Analysis of the 1064 nm Raman vibrational spectrum of K2[TCNE]2 possessing isolated π‐[TCNE]22− (TCNE=tetracyanoethylene) dimers shows several low‐energy symmetric intradimer breathing modes at 198, 173, 155, 131, 107, and 85 cm−1. These data confirm the presence of a long two‐electr...

Description
Summary:Long CC bonds: Analysis of the 1064 nm Raman vibrational spectrum of K2[TCNE]2 possessing isolated π‐[TCNE]22− (TCNE=tetracyanoethylene) dimers shows several low‐energy symmetric intradimer breathing modes at 198, 173, 155, 131, 107, and 85 cm−1. These data confirm the presence of a long two‐electron/four‐center CC bond (see picture).
