The cocrystal aqua-chlorido{6,6'-di-tert-butyl-2,2'-[1,2-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato-?O,N,N',O'}-manganese(III)-chlorido{6,6'-di-tert-butyl-2,2'-[1,2-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato-?O,N,N',O'}(methanol-?O)manganese(III) (1/1).

ABSTRACT: The asymmetric unit of the title complex, [Mn(C(28)H(30)N(2)O(2))Cl(H(2)O)][Mn(C(28)H(30)N(2)O(2))Cl(CH(3)OH)], contains two discrete Mn(III) complexes of a Schiff base ligand, with an N(2)O(2) donor set. Both Mn(III) centers are in a distorted octa-hedral geometry with the N(2)O(2) donor atoms of the tetra-dentate Schiff base dianion in the equatorial plane. The axial positions in the coordination environment of one Mn(III) complex are occupied by a chloride ion and a water mol-ecule, but a methanol mol-ecule replaces the water mol-ecule in the other complex. The coordinated water mol-ecule takes part in an O-H?Cl hydrogen bond between the two Mn(III) complexes. In the crystal structure, O-H?Cl hydrogen bonds link the mol-ecules into infinite one-dimensional chains along the [100] direction. The crystal structure is stabilized by O-H?Cl hydrogen bonds together with weak C-H?O and C-H?Cl inter-actions. A C-H?? inter-action is also observed in the crystal structure.
