A 3-D Fe^II Hofmann-type framework material has been prepared which contains a three-connecting pyridyl-donor ligand with amide functionality and [Au(CN)₂]⁻ metallo-ligands. The Fe^II sites display a rare Fe^II(py)₃(N [triple bond, length as m-dash]

C⋯)₃ coordination environment, which we show for the first time to be conducive to spin crossover (SCO).
