Abstract top

In the title complex, [Mn(C5H7O2)2(NCS)(CH4O)], the MnIII atom has a slightly distorted octahedral coordination formed by five O atoms and one N atom. The equatorial positions are occupied by four O atoms of two acetylacetonate ligands, while the axial positions are occupied by the N atom of the thiocyanate anion and the O atom of the methanol molecule. In the crystal structure, complex molecules are linked by an intermolecular O-H...S hydrogen bond, forming a chain running along [101].

Comment top

Octahedral complexes of high-spin MnIII are good examples for investigating the Jahn-Teller distortions, because their geometry are always distorted from the ideal octahedron to the distorted one by the axial ligands. Here, we report the structure of an octahedral MnIII complex, whose synthesis has been reported early (Stults et al., 1975).

The molecular structure of the title complex is shown in Figure 1. The MnIII atom is six coordinated by five O atoms and one N atom. The geometry can be described as a distorted octahedron. Four equational positions are occupied by four O atoms coming from two acetylacetonate ligands with the average Mn—O bond length 1.909 Å, which is in agreement well with the corresponding distance in [Mn(acac)2(OH2)2]ClO4].2H2O. (Swarnabala et al., 1994). One SCN- ion and one methanol molecule are coordinated to the MnIII atom with trans positions, so that forming an octahedral geometry. The distance of Mn—Omethanol [2.289 (5) Å] is obviously longer than the bond lengths of Mn—Oacetylacetonate. The bond length of Mn—NSCN is 2.187 (6) Å, which is also consistent with that found in [Mn(acac)2(SCN)] (Stults et al., 1979). In the crystal structure, a molecular chain along the [101] direction is formed by an intermolecular H-bond between the O atom of the methanol molecule and the S atom of the SCN- ion (Table 1).

Experimental top

The title complex was synthesized according to the literature method (Stults et al. 1975). The single crystals suitable for X-ray diffraction were grown from a methanol solution after the solvent was partial evaporated. Anal. Calcd for C12H18MnNO5S: C 41.99, H 5.29, N 4.08; found: C 42.04, H 5.26, N, 4.11.

Refinement top

The O-bound H atom of the methanol molecule was located in a difference Fourier map and its coordinates were refined, with Uiso(H) = 1.5Ueq(O). The H atoms bound to C atoms were placed geometrically (C—H = 0.93–0.96 Å) and were refined as riding, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
