Water, in its numerous forms, has long captivated scientific inquiry, ranging from the intricate structures of ice to the complex arrangements of clathrate hydrates. Over twenty water structures have been found and proved to be ice, and new ice structures have recently been found, starting with clathrate hydrates which originally contains guest molecules such as inert gases inside the host water lattices. Among these numerous forms of water, clathrate hydrates represent a particularly fascinating subject due to their beautiful molecular architecture made of the simple triatomic molecule. Beyond their physicochemical interests, clathrate hydrates are known to play pivotal roles in areas such as energy resources and environmental science and technology . In their structures, water shows self-assembling around guest substances to make FK type polyhedral framework. Although they are open to exploring structures with many options for guest substances, their fragile framework of hydrogen bonds still makes it difficult to arrange water molecules as intended, which is a simple, small, and highly stable molecule that does not readily bind to other materials.
