Poly[diaqua-di-₃-malonato--pyrazine-dimanganese(II)]

Z.-F. Li, S.-W. Wang, Q. Zhang and X.-J. Yu

Abstract: The title compound, [Mn₂(C₃H₂O₄)₂(C₄H₄N₂)(H₂O)₂]_n, is isostructural with its Co^II, Ni^II, Zn^II and Cd^II analogues, and the complex resides on a crystallographic centre of inversion (at the pyrazine ring centroid). The Mn^II atoms are linked via coordinated malonates, forming a two-dimensional network with cavities. These sheets are further connected into a three-dimensional network by bridging pyrazine ligands which have inversion symmetry. The coordination geometry around the Mn^II atom is a tetragonally elongated octahedron, with pyrazine N and aqua O atoms at the axial positions.
