The solid-state structures of two metal-pyridine-sulfate compounds, namely -poly[[tetra-kis-(pyridine-κ)iron(II)]-μ-sulfato-κ:'], [Fe(SO)(CHN)] , (), and -poly[[tetra-kis-(pyridine-κ)cobalt(II)]-μ-sulfato-κ:'-[tetra-kis-(pyridine-κ)cobalt(II)]-μ-sulfato-κ,':''-[tris-(pyridine-κ)cobalt(II)]-μ-sulfato-κ:'], [Co(SO)(CHN)] , (), are reported. The iron compound () displays a polymeric structure, with infinite chains of Fe atoms adopting octa-hedral NO coordination environments that involve four pyridine ligands and two bridging sulfate ligands. The cobalt compound () displays a polymeric structure, with infinite chains of Co atoms. Two of the three Co centers have an octa-hedral NO coordination environment that involves four pyridine ligands and two bridging sulfate ligands. The third Co center has an octa-hedral NO coordination environment that involves three pyridine ligands, and two bridging sulfate ligands with one sulfate chelating the cobalt atom.
