摘要：

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 "quasichair" 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 I-h, 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 angstrom).
