Tris(μ(2)-methano-lato)-μ(3)-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, [Mn(3)(C(14)H(12)ClN(2)O)(3)(CH(3)O)(3)O]ClO(4)·1.1CH(2)Cl(2)·0.9C(4)H(10)O, the cation consists of a central Mn(3)O core with μ(2)-methano-late bridging between adjacent Mn(III) atoms, thus giving each Mn(III) atom a mer-O(3) coordination environment. Six-coordination for each Mn(III) 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.
