This journal is © The Royal Society of Chemistry, 2026.A metal–organic framework (MOF), UoB-200, with a necklace topology that exhibits rare 1D → 1D parallel interpenetration is reported. UoB-200 exhibits significant negative linear compressibility (NLC) over a pressure range up to 3.44 GPa. When pressure is applied, elongation along the crystallographic c axis is observed via a wine-rack mechanism. The experimental results are modelled by simulations, which closely reproduce the mechanical response and suggest that the presence of solvent within the UoB-200 pores has minimal impact on the NLC behaviour at comparatively low pressures.
