title: trans-Bis(acetato-κO)diaquabis-(2-amino-pyrazine-κN)manganese(II) dihydrate.
abstract: The Mn(II) atom in the title compound, [Mn(CH(3)COO)(2)(C(4)H(5)N(3))(2)(H(2)O)(2)]·2H(2)O, is situated on a center of inversion and shows an octa-hedral coordination polyhedron made up by four O atoms and two N atoms. The octa-hedron is somewhat tetra-gonally distorted owing to the longer Mn-N bond [2.323 (3) Å]. The mononuclear complex mol-ecule and uncoordinated water mol-ecules are linked by O-H⋯N, N-H⋯O and O-H⋯O hydrogen bonds, generating a three-dimensional network.
