摘要:
Tetrahydrofuran (thf) adducts of a chlorobismuthate(III) and of antimony triiodide have been pre and characterized by X-ray crystallography. The former compound, bis[tetrakis(tetrahydrofuran-O)-lithium(I)] di-mu-chloro-bis[trichloro(tetrahydrofuran-O)-bismuthate(III)], [Li(C4H8O)(4)](2)[Bi2Cl8(C4H8O)(2)], contains centrosymmetric edge-shared bi-octahedral dianions with the formula [Bi2Cl6(thf)(2)(mu-Cl)(2)](2-) in which the thf ligands occupy terminal sites at 90 degrees to the Bi-2(mu-Cl)(2) plane; the cations are [Li(thf)(4)](+). The latter structure, triiodo(tetrahydrofuran-O)antimony(III), [SbI3(C4H8O)], comprises a polymeric arrangement of SbI3(thf) units, the antimony centres being bridged alternately by pairs of I atoms and pairs of thf ligands.
