Channels:
 
[001] 12 6.4 x 7.0* <-> [100] 10 4.5 x 5.1* <-> [010] 10 4.5 x 5.1*
Dimensionality
  Sorption (molecular cross section > 3.4Å): 3-dimensional
  Topological (pore opening > 6-ring): 3-dimensional
    Note:
The 10-ring shown on the right (viewed along [010]) limits the channel dimensions of both 10-ring channels (along [100] and along [010]).
