In the title one-dimensional coordination polymer, [Mn(NCS)3(C10H16N3)]n, the MnII atom is coordinated by an N,N′-bidentate Schiff base and four thiocyanate ligands in a distorted octahedral N5S geometry. Bridging thiocyanate ligands interconnect adjacent [Mn(NCS)2(C10H16N3)] units, giving rise to helical chains extending along the b axis. The chains are further linked through N—H⋯S hydrogen bonds, leading to a three-dimensional supramolecular network.

A mixture of 2-pyridinecarboxaldehyde (0.107 g, 1 mmol) and N,N-dimethylethyldiamine (0.088 g, 1 mmol) in ethanol (5 ml) was refluxed for 2 h followed by addition of a solution of Mn(ClO4)2.6H2O (0.362 g, 1 mmol) and KNCS (0.291, 3 mmol) in a minimum amount of water. The resulting solution was refluxed for 30 min, then set aside at room temperature. Crystals of the title compound suitable for X-ray analysis were obtained after few days on slow evaporation of the solvent.
Hydrogen atoms were located in a difference Fourier map or placed at calculated positions (C—H = 0.95–0.99 Å; N—H = 0.87 Å), and were treated as riding on their parent atoms, with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(C, N) for amine and methyl H atoms.
The title compound (Fig. 1) was obtained upon complexation of the Schiff base N,N-dimethyl-N'-[(pyridin-2-yl)methylene]ethane-1,2-diamine with Mn(ClO4)2 and KNCS. Similarly to what observed in a related platinium(II) complex (Hinman et al., 2000), due to the protonation of the amine nitrogen atom the Schiff base acts as a bidentate ligand instead as tridentate (Mukherjee et al., 2002). The Mn(II) ion is in a distorted octahedral coordination environment, provided by an N,N'-bidentate Schiff base and four NCS ligands. The µ2-isothiocyanato ligands interconnect the [Mn(NCS)2(C10H16N3)] units, giving rise to one-dimensional helical chains along the b axis. Adjacent helical chains are further connected via N—H···S hydrogen bonds (Table 1) into a three-dimensional supramolecular structure.

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. |

The title compound (Fig. 1) was obtained upon complexation of the Schiff base N,N-dimethyl-N'-[(pyridin-2-yl)methylene]ethane-1,2-diamine with Mn(ClO4)2 and KNCS. Similarly to what observed in a related platinium(II) complex (Hinman et al., 2000), due to the protonation of the amine nitrogen atom the Schiff base acts as a bidentate ligand instead as tridentate (Mukherjee et al., 2002). The Mn(II) ion is in a distorted octahedral coordination environment, provided by an N,N'-bidentate Schiff base and four NCS ligands. The µ2-isothiocyanato ligands interconnect the [Mn(NCS)2(C10H16N3)] units, giving rise to one-dimensional helical chains along the b axis. Adjacent helical chains are further connected via N—H···S hydrogen bonds (Table 1) into a three-dimensional supramolecular structure.
