In the title complex, [MnCl2(C13H13N3)]·H2O, the MnII atom is in a distorted square-pyramidal environment, with an Addison τ parameter of 0.037. The coordination geometry is defined by three N-atom donors from the tridentate 2-(pyridin-2-yl)-N-(pyridin-2-ylmethylidene)ethanamine ligand and two terminal Cl atoms. Although the H atoms of the lattice water molecule were not located, O⋯O distances of 3.103 (7) Å and O⋯Cl distances of 3.240 (3) and 3.482 (4) Å suggest that hydrogen bonding is responsible for the stabilization of the crystal packing.

[(2-pyridyl)-N-(2-pyridylmethyl)ethanamine] (0.2133 g, 1 mmol) was dissolved in 20 ml of methanol. To the resulting solution, MnCl2.4H2O (0.1979 g, 1 mmol) was added. Immediate color change was observed. The mixture was stirred at room temperature during 2 h. The solution was filtered off and concentrated to tenth. Crystals that separated from the brown solution were filtered off and recrystallized in methanol. On standing for two weeks, suitable X-ray crystals were obtained. Yield: 65%. Anal. Calc. for [C13H15Cl2N3OMn] (%): C, 43.97; H, 4.26; N, 11.83. Found: C, 43.72; H, 4.80; N, 11.77. Selected IR data (cm-1, KBr pellet): 1635.
All H(C) atoms were located in difference maps. They were then treated as riding in geometrically idealized positions, with C—H = 0.93 (aryl), or 0.97 Å (CH2), and with Uiso(H)=1.2 Ueq(C). Water-H atoms could not be detected reliably. One low-resolution reflection (111) was omitted due to beamstop shading (OMIT instruction in SHELX97-L)).
In the title compound, the MnII ion displays a fivefold coordination geometry by three nitrogen atoms from the ligand molecule and two chloride atoms in terminal positions. A non-coordinated solvent water molecule is present. The bond lengths between the N atoms and the metal ion vary between 2.226 (3) Å [Mn1—N2] and 2.259 (3) Å [Mn1—N1]. These values are comparable to the bond lengths in similar manganese complex [2.2227 (16)–2.2628 (16) Å] (Marzec et al., 2011). The Mn—Cl bond distances are 2.4554 (11) Å for Mn1—Cl1 and 2.4338 (10) Å for Mn1—Cl2. The Cl1—Mn1—Cl2 measures 99.89 (4)° and the angles between the MnII ion and the coordinating N atoms located in the basal plane vary between 74.40 (11) ° [N2—Mn1—N3] and 159.28 (11)° [N3—Mn1—N1]. The largest angles around the MnII center are: β=N2—Mn—Cl2=161.52 (8)° and α = N1—Mn—N3=159.28 (11)°. Since the distortion value of the τ=(β-α)/60, is evaluated by the two largest angles a in five-coordination geometry (Addison et al., 1984), the value of τ=0.037 which can be compared with the ideal value of 1 for a trigonal-bipyramidal environment and 0 for a square-pyramidal environment, indicates a distorted square-pyramidal geometry around the Mn center with N1, N2, N3, and Cl2 in the plane. The apical position is occupied by Cl1. The configuration around C8 is assigned to be E, as the torsion angles N2—C8—C9—C10 and C7—N2—C8—C9 are 178.9 (3)° and -178.7 (3)°, respectively.

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. |

In the title compound, the MnII ion displays a fivefold coordination geometry by three nitrogen atoms from the ligand molecule and two chloride atoms in terminal positions. A non-coordinated solvent water molecule is present. The bond lengths between the N atoms and the metal ion vary between 2.226 (3) Å [Mn1—N2] and 2.259 (3) Å [Mn1—N1]. These values are comparable to the bond lengths in similar manganese complex [2.2227 (16)–2.2628 (16) Å] (Marzec et al., 2011). The Mn—Cl bond distances are 2.4554 (11) Å for Mn1—Cl1 and 2.4338 (10) Å for Mn1—Cl2. The Cl1—Mn1—Cl2 measures 99.89 (4)° and the angles between the MnII ion and the coordinating N atoms located in the basal plane vary between 74.40 (11) ° [N2—Mn1—N3] and 159.28 (11)° [N3—Mn1—N1]. The largest angles around the MnII center are: β=N2—Mn—Cl2=161.52 (8)° and α = N1—Mn—N3=159.28 (11)°. Since the distortion value of the coordination polyhedron, τ=(β-α)/60, is evaluated by the two largest angles a in five-coordination geometry (Addison et al., 1984), the value of τ=0.037 which can be compared with the ideal value of 1 for a trigonal-bipyramidal environment and 0 for a square-pyramidal environment, indicates a distorted square-pyramidal geometry around the Mn center with N1, N2, N3, and Cl2 in the plane. The apical position is occupied by Cl1. The configuration around C8 is assigned to be E, as the torsion angles N2—C8—C9—C10 and C7—N2—C8—C9 are 178.9 (3)° and -178.7 (3)°, respectively.
