A Two‐Dimensional Supramolecular Ice Layer Containing “Quasi‐Chair” (H₂O)₆ Hexagons Templated by Organic Carboxylic Host

Abstract

Despite a myriad of investigations have been performed both experimentally and theoretically, water remains not fully understood. Here, a new two‐dimensional (2D) supramolecular ice layer, which containing (H2O)6 hexagonal rings with “quasi‐chair” conformation, has been templated by an organic carboxylic host 1‐methyl‐4‐imidazole‐carboxylic acid. This unique infinite 2D ice layer, which is almost identical to ice Ih, packed into three‐dimensional architecture via hydrogen bonding contacts regulated by 1D chains of organic hosts, giving a slit‐width between adjacent layers of about 1.2 nm (12 Å).

Reversibly Stretching Cocrystals by the Application of a Magnetic Field

“…In other words, the physical/chemical properties of the stretched cocrystal should be closer to its coformers, when compared with the unstretched cocrystal. To verify this conclusion, vibrational spectra (IR and Raman), Hirshfeld surfaces analysis, and thermal studies (TGA and DSC) for cocrystals 1 -0.0T, 1 -0.5T, and 1 -1.0T were performed. The IR spectra showed no discernible difference (Figure S5), but the Raman spectra did (Figure ): that is, the more stretching effect on the cocrystal, the closer were Raman spectra to the individual 4,5-dci, which confirmed the above conclusion.…”
