<p>Di-μ4-oxido-di-μ3-oxido-bis(μ3-4-chlorobenzoato)-hexakis(μ-4-chlorobenzoato)-bridged octanuclear manganese(II,III) complex with 1,3-bis(3-methoxy-5-nitrosalicylideneamino)-2-propanol (H3mnsap), [Mn8(μ-mnasp)2(μ4-O)2(μ3-O)2(μ3-ClC6H4COO)2(μ-ClC6H4COO)6(CH3OH)2(H2O)2]·2CH3OH·C2H5OC2H5, was prepared, and the crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. The complex crystallizes in in the triclinic space group P1 with a = 13.6900(16)Å, b = 14.8751(17)Å, c = 16.1495(18)Å, α = 90.665(2)°, β = 105.392(2)°, γ = 115.948(2)°, V = 2820.0(6)Å3, Dx = 1.694 g/cm3, and Z = 1. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0672 and 0.1864, respectively, for all 12624 independent reflections. A crystal-structure analysis revealed a crystallographic centrosymmetric mixed-valent octanuclear MnII2MnIII6 complex, where two MnII MnIII dinuclear moieties bridged by alcoholato-oxygen of mnasp3− are connected by two μ3-oxido and two μ4-oxido oxygen atoms and six syn-syn-bridging and two monoatomic bridging plus syn-syn-bridging of 4-chlorobenzoate ligands to a defective double-cubane MnIII4 moiety.</p>
