Abstract:

In the title compound, [MnBr(C(10)H(9)N(3))(2)(H(2)O)]Br, the Mn(II) ion is six-coordinated in a considerably distorted cis-N(4)BrO octa-hedral environment defined by four N atoms of two chelating di-2-pyridyl-amine (dpa) ligands, one Br(-) anion and one O atom of a water ligand. As a result of the different trans effects of Br, N and O atoms, the Mn-N bond trans to the Br atom is slightly longer than the Mn-N bond trans to the N or O atoms. In the crystal, the dpa ligands are not planar, the dihedral angles between the two pyridine rings being 29.2 (4) and 28.2 (3)°. The complex cations and the Br(-) anions are linked by inter-molecular O-H⋯Br and N-H⋯Br hydrogen bonds. Inter-molecular π-π inter-actions are present between the pyridine rings, with a centroid-centroid distance of 3.793 (4) Å.
