title: cis-Dichloridobis(di-2-pyridyl-amine-κN,N')manganese(II).
abstract: In the title complex, [MnCl(2)(C(10)H(9)N(3))(2)], the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)Cl(2) octa-hedral environment defined by four N atoms of two chelating di-2-pyridyl-amine (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 mol-ecules are stacked in columns along the c axis and are connected by inter-molecular N-H⋯Cl hydrogen bonds, forming a three-dimensional network. Weak inter- and intra-molecular π-π inter-actions are present between the pyridine rings, the shortest centroid-centroid distance being 4.406 (3) Å.
