Channels:
 
{([010] 8 3.3 x 3.5 <-> [100] 8 3.6 x 3.9*) <-> ([001] 8 3.6 x 3.6* <-> [100] 8 3.7 x 3.9* <-> [001] 8 3.8 x 3.9*)}**
Dimensionality
  Sorption (molecular cross section > 3.4Å): 2-dimensional
  Topological (pore opening > 6-ring): 2-dimensional
    Note:
There is no channel along [010], it is only one 8-ring connection of channel A to the main 2-D channel system
