trans-Bis(acetato-κO)diaquabis(2-aminopyrazine-κN4)manganese(II) dihydrate

The MnII atom in the title compound, [Mn(CH3COO)2(C4H5N3)2(H2O)2]·2H2O, is situated on a center of inversion and shows an octahedral coordination polyhedron made up by four O atoms and two N atoms. The octahedron is somewhat tetragonally distorted owing to the longer Mn—N bond [2.323 (3) Å]. The mononuclear complex molecule and uncoordinated water molecules are linked by O—H...N, N—H...O and O—H...O hydrogen bonds, generating a three-dimensional network.
