Source of material

Synthesis of the ligand HL: 1-{4-[(3,5-Dichloro-2-hydroxy benzylidene)amino]phenyl}ethanone O-methyl oxime: All chemicals were used without further purification. 4-Amino acetophenone methoxy oxime was prepared by an similar method reported earlier [1], [2], [3]. 3,5-Dibromosalicylaldehyde (279.91 mg, 1 mmol) in EtOH (5 mL) was added slowly to a solution of 4-amino acetophenone methoxy oxime (164.09 mg, 1 mmol) in EtOH (5 mL) at 338 K. The precipitate was heated, stirred and kept refluxing for 12 h at the same temperature. Then the mixture was cooled down to room temperature and the yellow precipitates were filtered and washed successively. The isolated raw product was dried under reduced pressure and purified (yield 71.3%, m.p.: 410–411 K). Elemental analysis – Anal. calcd for C16H14Cl2N2O2: C, 56.99%; H, 4.18%; N, 8.31%; Found: C, 57.02%; H, 4.20%; N, 8.25%.

Synthesis of the Mn(III) complex: A solution of Mn(CH3COO)2⋅4H2O (2.45 mg, 0.01 mol) in EtOH (3 mL) was added slowly to a solution of HL (6.72 mg, 0.02 mmol) in acetone (3 mL) at room temperature. The color of the mixture turned to brown immediately. The mixture was filtered after being stirred for 2 h at room temperature and the filtrate was allowed to stand for 10 days at room temperature, the solvent was partially evaporated and we obtained several clear dark brown crystals suitable for X-ray crystallographic analysis. Anal. calcd. for C40H40Cl8Mn4O16: C, 37.53%; H, 3.15%; Mn, 17.17%. Found: C, 37.49%; H, 3.12%; Mn, 17.26%.

Experimental details

Molecular structure was refined using the SHELX-14/7 package. Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.

Discussion

Oxime-type compounds with a general formula of R1R2C = N-OR3 are synthesized by condensation reaction of aldehydes or ketones with hydroxylamine. These compounds can be used as potential chelating agents and excellent coordination abilities with many metals [4], [5], [6], [7], [8], [9]. Oxime-type compounds and their complexes could be applied in many fields, such as magnetic materials [10], [11], [12], optical materials [13], [14], [15] etc. Herein we report on a new Mn(III) complexes, which may be related to literature known manganese complexes [16], [17], [18], [19].

The title complex consists of four Mn(III) atoms, two 4-(3,5-dichloro-2-hydroxy-phenyl)-3-[(3,5-dichloro-2-hydroxy-phenyl)-hydroxy-methyl]-4-hydroxy-butan-2-one ligands as well as methanolato and methanol ligands (cf. the figure). Mn1 and Mn1i atoms are five-coordinated, but Mn2 and Mn2i atoms are six-coordinated. Mn1/Mn1i has a distorted square-pyramidal coordination environment with three oxygen atoms from (L)4− and two oxygen atoms provided by two methanolato ligands. Mn2/Mn2i has a distorted octahedral coordination environment with three oxygen atoms from (L)4− and three oxygen atoms provided by two methanolato ligands and one oxygen atom of a coordinated methanol molecule. Bond lengths and angles are all in the expected ranges.
