Reactions of ClF3 with Main Group and Transition Metal Oxides: Access to Dioxychloronium(V) Fluoridometallates and Oxidofluoridometallates

“…The experimental and calculated vibrational frequencies are listed in Table 8. Similar vibrational frequencies were reported for [ClO 2 ] + in compounds such as [ClO 2 ][GeF 5 ], [ClO 2 ][ M F 6 ] ( M =Ru, Pt, Au, Sb), [ClO 2 ][ClO 4 ], [ClO 2 ][Cd(ClO 4 ) 3 ], [ClO 2 ][Au(ClO 4 ) 4 ] and [ClO 2 ][ M (ClO 4 ) 4 ] ( M =In, Tl) [34,37,40,42,43,115–118] . This indicates a minor effect of the anions and bridging atoms (O or F) on the vibrational frequencies of the [ClO 2 ] + cation.…”

“…Due to the shorter Cl−O bonds in comparison to the much longer Cl ⋅ ⋅ ⋅ μ−F interactions, the Cl atom is displaced from the center of the coordination polyhedron. In comparison to previously reported crystal structures of [ClO 2 ] + compounds, such as [ClO 2 ][BF 4 ], [ClO 2 ][RuF 6 ], [ClO 2 ][SbF 6 ], [ClO 2 ][Sb 2 F 11 ], or [ClO 2 ][ClO 4 ], the coordination number of the Cl atom is unexpectedly high [34,39,41,43,44] . Usually, only four short contacts of O or F atoms from surrounding anions are observed.…”

“…13) with two formula units per unit cell, Pearson code mP 20, and Wyckoff sequence 13. g 4 fe . The compound is, as are [ClO 2 ][SbF 6 ] and [BrO 2 ][SbF 6 ], isotypic to [ClO 2 ][RuF 6 ] [43] . Selected crystallographic data and details of the structure determination are given in Table 1.…”

“…In the case of [ClO 2 ] + cations, reactions of Cl 2 O 6 (“[ClO 2 ][ClO 4 ]”) with metals or chlorides often lead to the formation of dioxychloronium(V) perchloratometallates, where [ClO 4 ] − anions are bound as ligands [35–40] . Crystal structures of [ClO 2 ] + salts with the following anions have been reported: [BF 4 ] − , [GeF 2/2 F 4/1 ] − , [RuF 6 ] − , [SbF 6 ] − , [Sb 2 F 11 ] − , [ClO 4 ] − , [Au(ClO 4 ) 4 ] − and [Sn(ClO 4 ) 6 ] 2− [34,37–44] . Recently, compounds were published containing the complex [Cl 2 BrO 6 ] + cation that might be considered as a central [BrO 2 ] − anion coordinating to two [ClO 2 ] + cations [45] …”

Difluorochloronium(III) Fluoridometallates – from Molecular Building Blocks to (Helical) Chains

“…Crystal structures were reported for ClF 2 [BF 4 ] and ClF 2 [MF 6 ] (M = Nb, Ta, Ru, Os, As, Sb, Bi). [9,10,[22][23][24][25][26] In the reported crystal structure of ClF 2 [OsF 6 ], a disordered ClF 2 + cation was proposed, which prompted us to redetermine some of the reported crystal structures.…”
