• The central structural motif of the title coordination polymer, [Co(C 4 H 4 N 2 )(CH 3 CN) 2 (H 2 O) 2 (NO 3 ) 2 ] n , is a chain composed of Co II ions linked by bis-monodentate bridging pyrazine ligands through their N atoms. Nitrate anions are situated in the space between the Co II chains The central structural motif of the title coordination polymer, [Co(NO 3 ) 2 (C 4 H 4 N 2 )(CH 3 CN) 2 (H 2 O) 2 ] n , is a chain composed of Co II ions linked by bis-monodentate bridging pyrazine ligands through their N atoms. The Co II ion is located on an inversion center and is additionally coordinated by two O atoms of water mol­ecules and two N atoms of aceto­nitrile mol­ecules. The resultant N 4 O 2 coordination sphere is distorted octa­hedral. The linear cationic chains extend parallel to the a axis and are aligned into layers parallel to the ac plane. Nitrate anions are situated in the space between the Co II chains and form O—H⋯O hydrogen bonds with the coordinating water mol­ecules, leading to a three-dimensional network structure. Weak C—H⋯O hydrogen bonds are also present between pyrazine or aceto­nitrile mol­ecules and the nitrate anions.
