Crystal structure of catena-poly[[[trans-bis(aceto­nitrile-κN)diaquacobalt(II)]-μ-pyrazine-κ2 N:N′] dinitrate]


The central structural motif of the title coordination polymer, [Co(NO3)2(C4H4N2)(CH3CN)2(H2O)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 mol-ecules and two N atoms of aceto-nitrile… (More)
