Chiral metal–organic and supramolecular interpenetrating 3-D frameworks constructed by one angular ligand and 4,4′-dipyridine

The self-assembly of 1,3,4-thiadiazole-2,5-di-4-pyridyl (L1), 4,4′-dipyridyl (L2) with Zn(II), Cu(II) salts afforded one unusual coordination polymer with left-handed homo-chiral 3-D open MOFs in which supramolecular left-handed methanol helices were selectively formed, and one 2-D coordination polymer where two-fold interpenetrated 3-D supramolecular frameworks were constructed by hydrogen bonds.

One left-handed homo-chiral 3-D metal–organic open framework hosting supramolecular left-handed methanol helices and one two-fold interpenetrated 3-D supramolecular framework have been constructed and structurally characterized.Figure optionsDownload as PowerPoint slide
