资源简介:
Metal-center-driven spontaneous resolution of a chiral coordination polymer, [Ni­(SDB)­(BIX)]n (1), from achiral precursors has been probed by single-crystal X-ray diffraction and circular dichroism spectroscopy. Enantiomorphs 1P and 1M showed a parallel interpenetrated 2D → 3D chiral framework with (82.10) topology. Switching of the metal center under the same reaction parameters resulted in isostructural achiral and noninterpenetrating (4,4) grid-type sql networks [M­(SDB)­(BIX)]n, where M = CoII, ZnII, and CdII for 2–4, respectively.
