‖- (left) and ⊥-mode (right) EPR spectra of a (A) [MnIIIH3buea(O)]2−); and after addition of approximately (B) one and (C) three equiv of [FeCp2]+. The peak at g = 4.42 in the ⊥-mode spectrum in C is from excess [FeCp2]+. Experimental conditions, temperature, 10 K; microwave frequency, 9.29 (‖) or 9.62 (⊥) GHz.
