Crystal Structure of Te2O3F2

Single crystal growth and crystal structure of HgTeO2FOH—a layered fluorohydroxooxotellurate(IV) stabilized by weak F⋯OH interactions

“…Other crystallographically well-characterized representatives include H 2 Te 2 O 3 F 4 [10,11], (NH 4 )TeO(OH)F 2 [11], MTe(OH)F 4 (M = K, Rb) [12], as well as the double-salts Na 2 Te(OH)F 3 (SO 4 ) and (NH 4 ) 2 Te(OH)F 3 (SO 4 ) [13]. Further known structures are the related fluorooxotellurate(IV) KTeOF 3 [11], and the tellurium(IV) oxidefluorides Te 2 O 3 F 2 [14] and TeOF 2 [15]. Table 4. atoms are located at considerably longer distances of about 2.65 Å.…”

Synthesis and structure determination of In3TeO3F7: An indium oxyfluorotellurate IV derived from W bronze structure with Te4+ in hexagonal tunnels

“…Only slight improvements result from longer time or multiple annealing.

“…Introducing an extra anion as F − , acting as a modifier of tellurates IV environment, successively, new oxyfluorides, TeOF 2 [1] and Te 2 O 3 F 2 [2], oxyfluorotellurates: MTeO 3 F (M = Fe, Cr, Ga, In, Sc) [3,4], V 2 Te 2 O 7 F 2 [5], TiTeO 3 F 2 [5] and InTe 2 O 5 F [6] have been synthesized and structurally characterized. In these last phases, the trivalent or tetravalent cation associated to tellurium IV is in octahedral coordination.…”

New oxyfluorotellurates(IV):MTeO3F (M= FeIII, GaIIIand CrIII)

“…Following on from the structural characterization of the TeOF 2 (Guillet et al, 1999), Te 2 O 3 F 2 (Ider et al, 1996) and KTe 3 O 6 F (Laval et al, 2002) phases, this paper deals with the syntheses and crystal structure determination of a new isomorphous series of oxy¯uorides, MTeO 3 F, with M = Fe III , Ga III and Cr III .…”
