Partial packing diagram of [CsKA'2], illustrating some of the interchain contacts, predominantly K1…C8 at 3.20 Å, and Cs3…C22 at 3.44 Å, that promote sheet formation. The metal centers are colored in a pie chart fashion according to the proportion of K+ (purple) or Cs+ (pink) of each; translucent wedges (visible on K1 and Cs1) indicate the percentage of partial vacancy at the site. The C–C and C–Si bonds are rendered as sticks.
