Tris(μ2-methano-lato)-μ3-oxido-tris-{[(E)-4-chloro-2-({[2-(pyridin-2-yl)eth-yl]imino}-meth-yl)pheno-lato]manganese(III)} perchlorate-di-chloro-methane-diethyl ether (1/1.1/0.9).

In the title compound, [Mn3(C14H12ClN2O)3(CH3O)3O]ClO4·1.1CH2Cl2·0.9C4H10O, the cation consists of a central Mn3O core with μ2-methano-late bridging between adjacent MnIII atoms, thus giving each MnIII atom a mer-O3 coordination environment. Six-coordination for each MnIII atom is provided by the deprotonated Schiff base ligand (E)-4-chloro-2-({[2-(pyridin-2-yl)eth-yl]imino}-meth-yl)phenolate. There are extensive C-H⋯O and C-H⋯Cl inter-actions, which link the cations, anions, and solvent mol-ecules into a three-dimensional array.
