title: Tris(ethyl-enediamine)manganese(II) sulfate.
abstract: In the title compound, [Mn(C(2)H(8)N(2))(3)]SO(4), the metal atom (site symmetry 3.2) is coordinated by six N atoms from three ethyl-enediamine (en) ligands in a slightly distorted octa-hedral geometry. The en ligands are generated from one half-mol-ecule in the asymmetric unit. The O atoms of the sulfate anion (S site symmetry 3.2) are disordered over four orientations in a 0.220 (12):0.210 (13):0.203 (14):0.10 (2) ratio, with one of the O atoms having site symmetry 3. In the crystal, the ions are connected by N-H⋯O hydrogen bonds, forming a three-dimensional network.
