Structural chemistry of fluoride and oxofluoride complexes of titanium(IV)

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

“…The anion can be described with the Niggli formula . The structural chemistry of fluoridotitanates(IV) is rich and many different structural motifs have been described [81] . The simplest discrete anion of the fluoridotitanates(IV) is the [TiF 6 ] 2− anion, which has been observed in the crystal structures of salts such as A I 2 [TiF 6 ] ( A I =Li – Cs) and A II [TiF 6 ] ( A II =Ag, Ca, Sr, Ba) [82–87] .…”

Guanidinium Perfluoridotitanate(IV) Compounds: Structural Determination of an Oligomeric [Ti6F27]3– Anion, and an Example of a Mixed‐Anion Salt Containing Two Different Fluoridotitanate(IV) Anions

“…Together with [H 3 O][TiF 5 ], [H 3 O][Ti 2 F 9 ], [H 3 O] 2 [TiF 6 ], [H 3 O] 3 [Ti 6 F 27 ], [H 3 O][H 5 O 2 ][TiF 6 ] and [H 5 O 2 ] 2 [TiF 6 ] · 2H 2 O,, the [H 5 O 2 ] 4 [Ti 8 F 36 ] represents a new example of a compound prepared in the H 2 O/HF/TiF 4 system, showing the diversity of such a simple system.…”

“…The single‐crystal structure of [N(C 2 H 4 NH 3 ) 3 ][TiF 6 ]F was also determined, but was later corrected to [N(C 2 H 4 NH 3 ) 3 ][TiF 4,7 (OH) 1,3 ]F . Examples of the crystal structures of perfluoridotitanate(IV) compounds containing two different perfluoridotitanate(IV) anions were not known before this study , …”

Synthesis, crystal structure, and NMR investigation of 4-amino-1,2,4-triazolium hexafluoridotitanate(IV)

“…Isolated octahedral complex [TiF 6 ] 2À anions were found in crystal structures of a large number of hexafluoridotitanates(IV) [4]. Regular octahedral complex [TiF 6 ] 2À anions with Ti-F distances in the octahedron slightly different from 1.860 Å and F-Ti-F angles virtually equal to 90 and 1808 are present in just an insignificant number of structurally studied hexafluoridotitanates(IV) [4].…”

“…Isolated octahedral complex [TiF 6 ] 2À anions were found in crystal structures of a large number of hexafluoridotitanates(IV) [4]. Regular octahedral complex [TiF 6 ] 2À anions with Ti-F distances in the octahedron slightly different from 1.860 Å and F-Ti-F angles virtually equal to 90 and 1808 are present in just an insignificant number of structurally studied hexafluoridotitanates(IV) [4]. In all other studied structures of hexafluoridotitanates(IV), octahedral [TiF 6 ] 2À anions are insignificantly distorted at different degrees, whereas this degree of distortion and, therefore, the lengths of Ti-F bonds in the anion depend on the character of hydrogen bonds formed by F atoms and the effect of the outersphere cation.…”
