The preparation of 1,4,7-{NH(2-C6H4F)SiMe 2}3-1,4,7-triazacyclononane (H3N 3-F[9]N3) and 1,4,8-{N(H)PhSiMe2} 3-1,4,8-triazacycloundecane (H3N3[11]N 3), and their sodium derivatives Na3N 3-F[9]N3(THF)2 and Na3N 3[11]N3(THF)2, is described. The reaction of [TiCl3(THF)3] with Na3N3-F[9]-N 3(THF)2 and Na3N3[11]N 3(THF)2 leads to [Ti{N3-F[9]N3}] and (Ti(N3[11]N3)]. The titanium complexes react readily with I2 to give the TiIV derivatives [Ti{N 3-F[9]N3}]I and [Ti{N3[11]N3}]I. All titanium compounds display distorted trigonal prismatic geometries where the metal is coordinated to the six nitrogen donors. Fluxional processes that convert the conformations of the five- and six-membered metallacycles and the Δ and Λ enantiomers of [Ti{N3[11]N3}]I have been identified in solution.
