Titanium phosphonate clusters were synthesized by the reactions of titanium tetraisopropoxide (Ti(OiPr)(4)) with arylphosphonic acids (ArPO3H2, Ar = Ph, 1-Nap, 4-MeOPh, 4-FPh, 4-ClPh, 4-BrPh, and 4-BrBn) and H2O in tetrahydrofuran (THF) at room temperature. [Ti-4(mu(3)-O)(OiPr)(5)(mu-OiPr)(3)(O3PAr)(3)]center dot solv (Ar = Ph (1), 1-Nap (2), 4-MeOPh (3), 4-FPh (4), 4 ClPh (5); solv = thf for 1 and 2 or 2-propanol for 3-5) were isolated as new Ti4P3-type clusters, while Ti-7(mu(3)-O)(2)(OiPr)(6)(mu-OiPr)(6)(O3PBnBr)(6) (6) was isolated as a Ti7P6-type cluster. A co-crystal of Ti4P3- (7a) and Ti7P6-type (7b) clusters were obtained when 4-BrPhPO3H2 was used, and [Ti(OiPr)(acac)(O3PPh)](4) (8), a new cage cluster, was obtained when Ti(acac)(2)(OiPr)(2) (Hacac = acetylacetone) was reacted with PhPO3H2.
