Valence tautomeric transitions with thermal hysteresis around room temperature and photoinduced effects observed in a cobalt-tetraoxolene complex

J Am Chem Soc. 2006 Feb 15;128(6):1790-1. doi: 10.1021/ja057488u.

Abstract

A dinuclear complex, [(CoTPA)2(DHBQ)](PF6)3, has been successfully synthesized that exhibits a valence tautomeric transition with a distinct hysteresis effect (13 K) around room temperature and photoinduced valence tautomerism under low temperature.
