Connectivity pattern

Examples

The layers are stacked along the [001] direction using the following connectivity patterns

Symmetry Operation^*	Translation^*	Comment	Image
i	None	one inversion center shown as an open circle in the example
m	None	mirrow plane shown as a solid line in the example

^* relative to the previous layer


Effect on channel system
	The disorder does not block the channel system

Simplest ordered end members

The color of each layer reflects the symmetry/translation operation used to generate it from the previous layer (see table above).

	rth

In this space group and setting, the PerBUs are stacked along [001]
Adjacent layers generated by the same connectivity pattern (same basic color) are shown with different shades for clarity.

	Note: This polymorph corresponds to the ordered framework RTH
