摘要

A strongly anisotropic architecture of stacked metal–organic grids, with pores arranged through their eyes, has been revealed for the new coordination polymer Ni(bipy)(hip)(H_(2)O)_(2)·DMF·CH_(3)OH·H_(2)O, where bipy is 4,4′-bipyridine and hip is 5-hydroxyisophthalic acid. This porous crystal, when submerged in various nonpenetrating oils used as the hydrostatic media, displays a negative volume compressibility. This counterintuitive effect results in the zone amorphization injecting the contents of collapsing pores into the retained crystalline portions of the sample. This additional contents of the pores supports the crystalline parts and prevents their amorphization.
