摘要：Hydrated cation-pi interaction, as a kind of non-covalent interaction, is essential to the study of soft condensed matter. This paper reviews the recent progress in the two-dimensional crystals of unconventional stoichiometries induced by the hydrated cation-pi interaction, and their distinguished features. These crystals include Na2Cl, Na3Cl and CaCl at ambient conditions. These crystals have abnormal cation-anion ratios different from those of normal three-dimensional crystals and unique electronic structures. Consequently, their physical and chemical properties are usually different from those of normal three-dimensional crystals, including the room temperature ferromagnetism. These ferromagnetic materials of unconventional stoichiometries may provide new insight into biomagnetism, medicine.related magnetism and the design of low.dimensional ferromagnetic materials.
