Abstract

Calix[4]thiacrowns with hetero-L¹ and a homodonor set (L ²) were synthesized and characterized by X-ray analysis. From the reaction of L² with AgPF₆, disilver complex [Ag ₂(L²)](PF₆)₂ (1) was isolated. By comparing 1,3-alternate conformations of L² and 1, we found a considerable decrease of dihedral angles of two opposite aromatic rings upon complexation. This finding can be explained in terms of the "chopsticks process", which illustrates how Ag⁺-arene π-coordination occurs. Heterobinuclear complexation of L¹ in solution was also observed.
