Halogenation of tellurium by SO2Cl2. Formation and crystal structures of (H3O)[Te3Cl13]·1/2SO2, [(C4H8O)2H][TeCl5]·(C4H8O), [(Me2SO)2H]2[TeCl6], and [Ni(NCCH3)6][Te2Cl10]
摘要:
The halogenation of elemental tellurium with SO2Cl2 in various solvents has been investigated. (H3O)[Te3Cl13].1/2SO(2) (1) and [(C4H8O)(2)H][TeCl5].(C4H8O) (2) were obtained in CS2 and THF, respectively. When DMSO is added into the THF solution of tellurium and SO2Cl2, [(Me2SO)(2)H](2)[TeCl6] (3) is formed. In the acetonitrile solution tellurium and SO2Cl2 form [Ni(NCCH3)(6)][Te2Cl10] (4) in the presence of metallic nickel. All compounds 1-4 were characterized by Te-125 NMR and by Xray crystallography. The formation of the anions has been discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.
