Self-assembly of [Sn(OPMe)(CFSO)] metallocyclic Sn() hexamer stacks with CF-lined channel interiors
[Sn(OPMe 3 ) 3 (CF 3 SO 3 ) 2 ] 6 ( 1 ) self-assembles to form a highly unusual hexagonal metallocyclic array with bridging CF 3 SO 3 − groups. The discrete hexamers stack along the c -axis to form hydrophobic CF 3 -lined channels with an F F distance across the channel diameter of 0.8 nm. This Sn(...
