Crystal Structure of a Trinuclear Titanium(IV) Complex with (rac)‐3,3′‐Bis(methoxymethyl)‐BINOLate

Reaction of (rac)‐3,3′‐bis(methoxymethyl)‐BINOL [H 2 (CH 3 OCH 2 ) 2 BINO] with excess Ti(O i Pr) 4 and one equivalent of H 2 O in CH 2 Cl 2 affords a trinuclear titanium(IV) complex [{(CH 3 OCH 2 ) 2 BINO}Ti 3 ( μ 3 ‐O)(O i Pr) 6 ( μ 2 ‐O i Pr) 2 ]. By dissolving it in dichloromethane and hexane and cooling to 0 °C, plate‐like pale yellow single crystals (monoclinic, P 2 1 / n , a = 12.605(3), b = 21.994(5), c = 19.090(4) Å, β = 92.764(8)°, V = 5286.2(19) Å 3 , T = 293(2) K) were obtained. Each oxygen atom at 2 or 2′ position of the (CH 3 OCH 2 ) 2 BINO ligand bonds to only one titanium atom. There is no interaction between the third Ti atom and the two oxygen atoms of 3,3′‐bis(methoxymethyl)‐BINOLate.
