摘要

Dark red crystals of the composition H3OTeBr5 . 3 C4H8O2 (1) were isolated from a saturated solution of TeBr4 in 1,4-dioxane containing a small amount of water. In this compound (space group P2(1)/m, a = 8.922(4) Angstrom, b = 13.204(7) Angstrom, c = 9.853(5) Angstrom, beta = 91.82(4)degrees at 150 K) a square pyramidal TeBr5(-) anion has been isolated for the first time. The coordination sphere of the anion is completed to a distorted octahedron by weak interaction with a dioxane molecule of the cationic system. The (HO)-O-3(+) cations are connected to chains by dioxane molecules. At room temperature the compound is stable only in its mother liquor. CrystallineH3O(2)SeBr6 (2) (space group Fm3m, a = 10.421(1) Angstrom at 170 K) is a bromoselenous acid of high symmetry. The H3O(+) ion is only weakly coordinated by Br atoms of the anion. The anions are isolated octahedral SeBr6(2-) units. The structure is isotypic to the K-2PtCl6 structure. Despite being a halogeno-chalcogen(IV) acid, 2 exhibits a remarkable thermal stability. Both oxonium compounds were characterized by single-crystal X-ray structure analyses. Vibrational spectra of 2 are reported. References: 20
