In the title complex, [MnCl2(C10H9N3)2], the MnII ion is six-coordinated in a considerably distorted cis-N4Cl2 octahedral environment defined by four N atoms of two chelating di-2-pyridylamine (dpa) ligands and two Cl− anions. In the crystal, the dpa ligands are not planar, the dihedral angles between the two pyridine rings being 29.3 (2) and 30.9 (2)°. The complex molecules are stacked in columns along the c axis and are connected by intermolecular N—H⋯Cl hydrogen bonds, forming a three-dimensional network. Weak inter- and intramolecular π–π interactions are present between the pyridine rings, the shortest centroid—centroid distance being 4.406 (3) Å.

To a solution of MnCl2.4H2O (0.1988 g, 1.005 mmol) in EtOH (20 ml) was added di-2-pyridylamine (0.3465 g, 2.024 mmol) and stirred for 3 h at room temperature. The formed precipitate was separated by filtration and washed with EtOH and acetone, and dried at 323 K, to give a white powder (0.2982 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a CH3CN solution.
Carbon-bound H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.95 Å and Uiso(H) = 1.2Ueq(C)]. Nitrogen-bound H atoms were located from Fourier difference maps then allowed to ride on their parent atoms in the final cycles of
with N—H = 0.92 Å and Uiso(H) = 1.5 Ueq(N). The highest peak (0.51 e Å-3) and the deepest hole (-0.56 e Å-3) in the difference Fourier map are located 1.40 Å and 1.08 Å from the atoms H9 and N4, respectively.Data collection: SMART (Bruker, 2000); cell

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. |

Neutral and cationic MnII complexes of the di-2-pyridylamine (dpa; C10H9N3) ligand, such as [MnX2(dpa)2].H2O, [MnX(dpa)2(H2O)]ClO4 (X = N3-, NCO-) (Bose et al., 2005) and [MnX(dpa)2(H2O)]X (X = I, Br) (Ha, 2011a,b), have been investigated previously.
In the title complex, [MnCl2(dpa)2], the MnII ion is six-coordinated in a considerably distorted cis-N4Cl2 octahedral environment defined by four N atoms of two chelating dpa ligands and two Cl- anions (Fig. 1). The main contributions to the distortion are the tight N—Mn—N chelating angles (Table 1), which results in non-linear trans axes [N3—Mn1—N4 = 161.55 (11)°, N6—Mn1—Cl1 = 173.54 (11)° and N1—Mn1—Cl2 = 170.18 (10)°]. Because the Mn—N bond lengths are nearly equivalent (Table 1), the different trans effects of the Cl and N atoms cannot be observed reliably. In the crystal structure, the dpa ligands are not planar, the dihedral angles between the two pyridine rings being 29.3 (2)° and 30.9 (2)°. The complex molecules are stacked in columns along the c axis and connected by intermolecular N—H···Cl hydrogen bonds, forming a three-dimensional network (Fig. 2, Table 2). In the columns, numerous weak inter- and intramolecular π—π interactions are present between the pyridine rings, the shortest centroid-centroid distance being 4.406 (3) Å.
