Zinc blende 9: the conformation of the six-membered rings

The six-membered rings in zinc blende all have the same conformation, namely the "chair" conformation, which is illustrated in green in the image above. By rotating the structure with your mouse you should be able to appreciate why it is called the chair conformation. The chair conformation is also the only conformation in the analogous structure of diamond. This is in contrast to its hexagonal analogue, wurtzite, where there are both chair and boat conformations.
