Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

We report two cyanido-bridged [FeCo] chains, {[FeIII(Tp)(CN)3][CoII(vim)4](BF4)•H2O•CH3CN} (1), {[FeIII(Tp)(CN)3][CoII(vim)4](BF4)•CH3CN} (2), (Tp: trispyrazolylhydroborate, vim: 1-Vinylimidazole) containing diamagnetic [FeIILS(S=0)-CoIIILS(S=0)] units in 2-300 K range. 1 undergoes photo-induced metal-to-metal-electron-transfer under light irradiation at low temperature with thermal relaxation around 80 K, whereas 2 is photo inactive.
