Why are water crystals hexagonal?

Many compounds, like water, even show multiple different stable crystal forms in reality (at different pressure, or at different temperature). Apparently, water molecules can energetically form nice 6-membered rings of hydrogen bonds, and such configurations appearing in the crystal structure make the hexagonal structure the best one. read more

On the other hand, unorganized water has been described surrounding diseased and abnormal cells. As shown above, Hexagonal Water is composed of six individual molecules of water, held together by common hydrogen bonds. This unique water structure is capable of rapid penetration within the cells of the body. read more

The hexagonal crystal family consists of two crystal systems: trigonal and hexagonal. A crystal system is a set of point groups in which the point groups themselves and their corresponding space groups are assigned to a lattice system (see table in Crystal system#Crystal classes). The trigonal crystal system consists of the 5 point groups that have a single three-fold rotation axis. read more
