The asymmetric unit of the title compound, [MnCl₂(C₁₁H₁₇N₃)], contains two crystallographically independent molecules with slightly different geometries. In each molecule, the Mn^II ion is five coordinated by the N,N′,N′′-tridentate Schiff base and two Cl atoms in a distorted square-pyramidal geometry. In the crystal, C—H

Cl hydrogen bonds link adjacent molecules into a three-dimensional network.

Comment top

The title compound was obtained upon complexation of the Schiff base, N,N-dimethyl-N'-[methyl(2-pyridyl)methylene]ethane-1,2-diamine, with MnCl₂. Similar to its analogous copper(II) complex (Saleh Salga et al., 2010), the metal center is five-coordinated by the N,N',N"-tridentate Schiff base and two Cl atoms. Two geometrically different molecules exist in the crystal structure. In both molecules, the Mn^II ions are in a square-pyramidal coordination environment with different degrees of distortion from the ideal geometry as revealed by the τ values of 0.101 for Mn1 complex and 0.035 for Mn2 complex. The weighted r.m.s. fit for the superposition of the non-H atoms in both molecules is 0.0868 Å. The Mn—Cl and Mn—N bond lengths in the two molecules are comparable with those in the related structures (Gibson et al., 2003; Reardon et al., 2002). In the crystal, the adjacent molecules are connected via C—H···Cl hydrogen bonds into a three-dimensional polymeric structure. The crystal structure contains void spaces with the size of 54.00 Å^-3 within which there is no evidence for included solvent.

Experimental top

A mixture of 2-acetylpyridine (0.61 g, 5 mmol) and N,N-dimethylethyldiamine (0.44 g, 5 mmol) in ethanol (50 ml) was refluxed for 2 hr followed by addition of a solution of manganese(II) chloride (0.63 g, 5 mmol) in a minimum amount of water. The resulting solution was refluxed for 30 min, then set aside at room temperature. The crystals of the title compound were obtained after a few days.

Special details top

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.
