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

Abstract

The crystal structures of 119 fluoride and oxofluoride complexes of titanium(IV) (88 fluoride and 31 oxofluoride compounds) published to date have been analyzed and reviewed. Depending on the degree and nature of the association of structural units, the analyzed structures can be divided into monomeric, dimeric, oligomeric, and polymeric, including chain and layered polymeric structures. The manuscript describes the occurrence of various structural motifs, the coordination and geometry of complex anions and cations, as well as the driving forces behind supramolecular crystal assembly. A comprehensive table is compiled to provide details about composition, values of terminal and bridging TiF and TiO bonds, as well as the corresponding references. A table of crystallographic data for the investigated fluoride and oxofluoride complexes of titanium(IV) is presented in the Appendix.
