To a stirred solution of Mn(CH3COO)2·2H2O (0.0662 g, 0.5 mmol) in methanol (25 ml) was added an equimolar quantity of (2-hydroxy 5-methoxy benzaldehyde and 1,2 diamino propane (0.171 g, 0.5 mmol). The pink solution turned dark brown immediately upon formation of the MnII complexes. To this solution was added 4 mmol of pyridine, and air was bubbled through the reaction mixture for about 3 h. 0.5 mmol of NH4PF6 was then added to the resulting dark brown solution and stirred for 5 minutes. A dark brown microcrystalline solid was formed by slow evaporation of methanol at room temperature. Brown single crystals of the MnIII complexes suitable for x-ray structure determination were obtained after recrystallization by slow evaporation from methanol/propanol (2:1 v/v) solution at room temperature after several days.
The H atom attached to the O atom of the methanol ligand was located in a difference map and isotropically refined. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with the C—H distances in the range 0.93–0.98 Å. The Uiso values were constrained to be 1.5Ueq of the carrier atom for methyl H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl groups.

Experimental. The low-temparture data was collected with the Oxford Cyrosystem Cobra low-temperature attachment. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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 > σ(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. |

Transition metal compounds containing Schiff base ligands have been of interest for many years (Kani et al., 2000; Habibi et al., 2007; Paschke et al., 2002), since they play an important role in the development of coordination chemistry, particularly in relation to catalysis and enzymatic reactions, as well as molecular magnetism (Cozzi et al., 2004; Darensbourg et al., 2006; Dimauro & Kozlowski, 2002). A considerable number of complexes with multidentate Schiff bases containing O,N donor atoms have been studied (Clarke et al., 1998; Marchetti et al., 1999). In this paper, we report the crystal structure of two co-crystallized MnIII-Schiff base complexes.
The asymmetric unit of the cocrystal (Fig. 1) consists of a mixture of 0.5[Mn(C19H20N2O2)(C5H5N)(CH3OH)], 0.5[Mn(C18H18N2O2)(C5H5N)(CH3OH)] and PF6. The difference between the two components of the co-crystal concerned the substituents on the C21 atom; in one case two H atoms were attached whereas in the other component one H atom is replaced by the methyl group (C22). The environment around MnIII shows a distorted octahedral geometry with the N2O2 of tetradentate Schiff base ligand as the basal plane. The two phenolic O atoms and two imine N atoms are in cis positions. The pyridine and methanol molecules are in the two axial positions. The Mn1—O1 and Mn1—O2 distances of 1.8909 (13) Å and 1.8655 (14) Å, and Mn—N1 and Mn1—N2 distances of 1.9764 (17) Å and 1.9887 (16) Å, respectively lie in the same range as observed for closely related MnIII complexes of Schiff base ligands (Mitra et al., 2006; Naskar et al., 2004). However there are elongations of the axial bonds Mn1—O5 = 2.2986 (16) Å and Mn1—N3 = 2.3532 (18) Å. The dihedral angle between the two benzene rings of the Schiff base ligand is 18.83 (9)°. One methoxy group is coplanar with the attached benzene ring while another one is slightly twisted out of the ring plane as indicated by the torsion angles C23—O3—C4—C5 = 0.6 (3)° and C24—O4—C11—C10 = -16.7 (4)°. Other bond lengths and angles in the ligands are in normal ranges (Allen et al., 1987).
In the crystal packing (Fig. 2), the methanol molecule is involved in an intermolecular O—H···O hydrogen bond and weak C–H···O intermolecular interactions linking the molecules into a network (Table 1, Fig. 2). Morover in the structure of [Mn(C19H20N2O2)(C5H5N)(CH3OH)] ion, a weak C–H···N interaction between the pyridine and the C22 methyl group was also present [C22—H22C···N3].
