✦ Synopsis

The title compound, [Mn(C 5 H 3 N 2 O 2 ) 2 (H 2 O)] n , prepared by hydrothermal synthesis, is isostructural with its Fe II , Co II , Ni II and Cu II analogues. The asymmetric unit contains two bidendate pyrazine-2-carboxylate anions coordinated to Mn II in the equatorial plane through one N and one O atom. The Mn II atoms are linked into chains by the second N atom of one of the pyrazine-2-carboxylate anions coordinating to an axial site of a neighbouring Mn II atom. The slightly distorted octahedral coordination around Mn II is completed by a water molecule, which forms hydrogen bonds to link the chains into a three-dimensional structure. The investigated crystal was an inversion twin.
