摘要

The treatment of EPh_2 (E = Te, Se) with Ag(O_3SCF _3) or Cu(O_3SCF_3)·1/2C_6H _6 in dichloromethane yields isomorphous complexes [Ag(TePh _2)_3](O_3SCF_3) (1), [Cu(TePh _2)_3](O_3SCF_3) (2), and [Cu(SePh _2)_3](O_3SCF_3) (3). The related reaction of TeTh_2 (Th = 2-thienyl, C_4H_3S) with Cu(O_3SCF_3)·1/2C_6H_6 affords [Cu(TeTh_2)_3](O_3SCF_3) (4). While not isomorphic with 1-3, its crystal structure bears a close relationship with them. The reaction of TeTh_2 or SePh_2 with Ag(O _3SCF_3) yields [Ag(TeTh_2)_2](O _3SCF_3) (5) and [Ag(SePh_2)_2](O _3SCF_3) (6), respectively. They form dinuclear complexes, the silver centers of which are coordinated to two terminal R_2E ligands and linked together by two bridging CF_3SO_3 ~- ligands. The dinuclear complexes further form supramolecular networks through π-π stacks of the aromatic rings. The treatment of Ag(O_3SCF_3) with Te(CH_2SiMe_3) _2 results in the formation of a mixture containing polynuclear [Ag{Ag[Te(CH_2SiMe_3)_2]}_4] _n(O_3SCF_3)_(5n) (7) and [Ag{Te(CH _2SiMe_3)_2}]_n(O_3SCF _3)_n (8). The cyclic repeating units in 7 are connected to polymeric chains by two bridging CF_3SO_3 ~- ligands. 8 contains a [-Ag-Te(CH_2SiMe_3)_2-] _n polymer. There are only weak van der Waals interactions between the polymer chains of 7 and 8.
