The reaction of the cyclotetraphosphate ion (P4O124-) with [Cp*TiCl3] (CP* = eta(5)-C5Me5) gives [(Cp*Ti)(2)(P4O12)(2)](2-) where the P4O12 ligands adopt a saddle conformation, while that with [(Cp*TiCl)(3)(mu-O)(3)] leads to [(Cp*Ti)(3)(mu-O)(3)(P4O12)](-) containing a crown form P4O12 ligand; both products feature their unique cage structures. On the other hand, the reactions of the cyclotriphosphate ion (P3O93-) with [(Cp*TiCl2)(2)(mu-O)] and [(Cp*TiCl)(3)(mu-O)(3)] afford [(Cp*Ti)(2)(mu-O)(P3O9)(2)](2-) and [(Cp*Ti)(3)(mu-O)(3)Cl(P3O9)](-), respectively, and in both cases the P3O9 ligands bridge two titanium centers with an eta(2):eta(1) mode.
