Supramolecular Framework with Two Different Kinds of Channels via Self-Assembly of 1D Coordination Polymers in a Prismatic Manner

Slow diffusion of Cu(ClO4)2 with p-C6H4(SiMe2(4-Py))2 yields a
supramolecular framework consisting of two kinds of channels via
self-assembly of a 1D double-stranded chain in a prismatic fashion.
The channel has a 11 × 11 Å2 cross section (Cu···C = 11.13 Å)
with a 6 × 6 Å2 square pore. The channels are infinitely arranged,
resulting in another kind of channel with similar pores. Thus, two
different kinds of channels with different solvate molecules coexist
in a 1:2 ratio. Weak C−H···π interaction may be one of the driving
forces in the assembly of the prismatic channel structure.
