1666: 1591: 2057: 1624: 2370:), the structure is more ordered, resulting in a higher degree of crystallinity and purer cookeite. However, this direct relationship between pressure and structure has been called into question by the discovery of several samples of different crystallinity in the same sample from a low-pressure zone. Cookeites from high pressure always exhibit a high degree of crystallinity, but ordered cookeites can also be found at low pressure. The low-crystallinity crystals assumed to be characteristic of low pressures simply haven't yet reached the 1940:
length of 1.66 Ă…. There are two T-O'-T layers in the r-cookeite: the first is located at the edge of the cell, around the (x, y, z=0) coordinate plane, and the second is located in the center of the cell, around the (x, y, z=1/2) coordinate plane. These two layers are identical and equivalent through the translatory mirror c with coordinates (x, y, z=1/4). Since the O' layer has only one vacant site in the cell, when the layers are stacked, the vacant sites of the two layers are shifted in the (

The cell parameter of cookeite IIa is half that of r-cookeite: the difference between these two structures is due to the stacking of the O and T-O'-T layers. Within the layers themselves, there is no notable structural difference between this cookeite and the r-cookeite. However, the dioctahedral O'

layers of cookeite IIa are all identical and ordered so as to have the vacant sites one above the other in the stacking direction of the layers, whereas in r-cookeite, due to the translatory mirror c, the vacant sites of the O' layers do not overlap.
