Formation and Crystal Structure of an Oxygen Bridged Titanium Amino Bisphenoxide Di‐(μ‐oxo)‐titan‐bis[aminobisphenoxide] ( 3 ) was obtained by reaction of ( i ‐Prop) 2 TiL* ( 2 ) {L* = O‐4, 6‐( t ‐Bu) 2 C 6 H 2 ‐2‐CH 2 ‐[1, 4‐N 2 C 5 H 10 ]‐2'‐CH 2 ‐4', 6'‐( t ‐Bu) 2 C 6 H 2 O] with water in a molar ratio 1:1 in diethylether. Both i ‐Propyl moieties are substituted yielding the dimeric oxygen bridged amino bisphenoxide complex. The six coordinate Ti atoms are a result of Ti—N and Ti—O interactions of the corresponding atoms of the amino bisphenoxide ligand and the bridging O atoms. The central planar Ti 2 O 2 ring may be considered as the general structural feature of the title compound: Space group P1¯, Z = 1, lattice dimensions at —60°C: a = 11.6899(4), b = 11.7873(4), c = 12.6462(4) Å, α = 98.070(1), β = 99.660(1), γ = 95.343(1)°, R 1 = 0.0469, wR 2 = 0.1049, GooF = 0.939.
