Generation and Characterization of the C₃ O₂ ^- Anion with an Unexpected Unsymmetrical Structure.

ABSTRACT: The carbon suboxide anion C₃ O₂ ^- is generated in solid neon matrix. It is characterized by infrared absorption spectroscopy as well as quantum chemical calculations to have a planar C_s structure where two CO groups with significantly different bond lengths and angles are attached in a zigzag fashion to the central carbon atom. Bonding analysis indicates that it is best described by the bonding interactions between a neutral CO in a triplet excited state and a doublet excited state of CCO^- .
