H2S is a potent two-electron reducing agent: the reactivity of fully oxidized complex with H2S was monitored by UV/Vis (A, left) and EPR (B, middle) spectroscopies. (C) (right): UV/Vis of oxidized Cyt. C (black) shows it could be reduced by H2S (dotted black). Reproduced with permission from Collman et al. (2009d).
