Whereas … WebAug 21, 2024 · Which structure a simple 1:1 compound like NaCl or CsCl crystallizes in depends on the radius ratio of the positive and the negative ions. If the radius of the positive ion is bigger than 73% of that of the negative ion, then 8:8-coordination is possible. Less than that (down to 41%) then you get 6:6-coordination.

Crystalline Canopy Theory - Carl Baugh
WebWhen water freezes into ice, the water molecules stack together to form a regular crystalline lattice, and the ice lattice has six-fold symmetry (see the Primer). It is this hexagonal crystal symmetry that ultimately determines the symmetry of snow crystals. But then one must ask how molecular forces, which operate at the molecular scale to ...
