Water-filled channels constructed by supramolecular complex of partial-cone thiacalix[4]arene tetrasulfonate

A novel crystal containing water-filled channel structures was prepared under hydrothermal conditions utilizing thiacalix[4]arene tetrasulfonate, Ni(ClO4)2, and 2,2′-bipyridine, in which thiacalix[4]arene tetrasulfonate molecules assumed the so-called partial-cone conformation.
