A new (3,18)‐connected 3D metal–organicframework [Co(PYNT)(H2O)2]n (ZZU‐1) (H2PYNT=5‐(3′‐carboxylphenyl) nicotic acid) has been reported. Amazingly, ZZU‐1 captureswatermolecules and transforms into the hydrated framework [Co3(PYNT)3(H2O)6]⋅H2O}n (ZZU‐2) at 160 °C in refluxing hydrated DMF, but not at 100 °C in refluxing neat water or from the solvothermal synthesis conducted at 90 °C (see figure)
