摘要

Three crystalline complexes were prepared by the inclusion complexation of p-sulfonatothiacalix[ 4] arene with [Cu(2-DPD) (2+)(2)] (2; 2-DPD represents 2,2'-dipyridine), [Cu( Phen)(2)(2+)] ( 4; Phen represents 1,10-phenanthroline), and [Co(Phen)(3)(2+)] ( 5), respectively. These crystal structures are comparable to those reported p-sulfonatothiacalix[ 4] arene complexes with 2-DPD ( 1), [Ni(2-DPD)(3)(2+)] ( 3), and 4,4'-dipyridine (4-DPD) ( 6), indicating that p-sulfonatothiacalix[ 4] arene in 2, 4, and 5 is cleft to a pinched cone (C-2v) to different extents upon cocomplexation with metal 2-DPD ( or Phen) complexes, while p-sulfonatothiacalix[ 4] arene in 1 maintains the conventional cone shape of C-4v symmetry with shallow inclusion of 2-DPD. Particularly, p-sulfonatothiacalix[ 4]arene assumes the partial-cone conformation in 3 and the 1,2-alternate conformer in 6, respectively. Furthermore, the assembly behavior of p-sulfonatothiacalix[ 4] arene is influenced dramatically by the presence of various guests, such as bilayer arrangements for 1 and 2, corrugated bilayers for 4 and 5, and even water-filled channels for 3 and hydrogen-bonded polymers for 6.
