AB - The compound [Mn<inf>2</inf><sup>III,Iv</sup>O<inf>2</inf>(bisimMe<inf>2</inf>en) <inf>2</inf>](ClO<inf>4</inf>)<inf>3</inf>·H<inf>2</inf>O (bisimMe<inf>2</inf>en = N,N′-dimethyl-N,N′-bis(imidazol-4-ylmethyl)ethane-1,2-diamine) was synthesized. It crystallizes in the monoclinic space group C2/c with a= 18.139-(8) Å, b = 12.694(5) Å, c - 17.694(8) Å, β = 107.5(6)°, V = 3885(6) Å<sup>3</sup>, and Z = 4. The cation [Mn<inf>2III Iv</inf>O<inf>2</inf>(bisimMe<inf>2</inf>en)<inf>2</inf>]<sup>3+</sup> contains a di-manganese di-μ-oxo unit. The Mn-Mn axis is a C<inf>2</inf> axis. The Mn-imidazole distances for Mn<sup>III</sup> or Mn<sup>IV</sup> are distinct: respectively, 2.208(9) and 2.004(8) Å. The ground state is a |S<inf>A</inf>=2,S<inf>B</inf>=3/2,S=1/2 state separated by 420 cm<sup>-1</sup> from the S = 3/2 state. The EPR spectrum has been simulated with |A<inf>1tA</inf>| = 160.10<sup>-4</sup>cm<sup>-1</sup>, |A<inf>1Z</inf>,.-| = 136.10<sup>-4</sup>Cm<sup>-1</sup>, \A<inf>2tA</inf>| = 72.10<sup>-4</sup> cm<sup>-1</sup>, |A<inf>2z</inf>|= 71.10<sup>-4</sup> cmn<sup>-1</sup>, g<inf>-ty</inf> = 1.997. g-= 1.993. The ESEEM spectrum is reported. The <sup>2</sup>H nuclei corresponding to the exchangeable hydrogen atoms of imidazole groups in D<inf>2</inf>O have been detected at 2.4 MHz at 3480 G. In cyclic voltammetry, [Mn<inf>2</inf><sup>III,Iv</sup>O<inf>2</inf>(bisimMe<inf>2</inf>-en) <inf>2</inf>]<sup>3+</sup> pr
