An open chain trinuclear titanium(IV) isopropoxide species formed with the tridentate ligand cis,cis–cyclohexane–1,3,5-trialkoxide [C6H9O3]3–. Crystal structure of [{Ti(OPri)3}2{µ-Ti(C6H9O3-O1,O5)2}]
Abstract
Reaction of titanium(IV) tetraisopropoxide with cis,cis-cyclohexane-1,3,5-triol [C6H9(OH)3, H3L] affords the novel trinuclear titanium(IV) alkoxide species [{Ti(OPri)3}2{µ-Ti(C6H9O3-O1,O5)2}] {L = [C6H9O3]3–} which possesses a unique open-chain V-shaped arrangement of three titanium atoms, with the central 6-co-ordinate Ti atom bonded to two tridentate L groups, and with each of the two terminal Ti atoms 5-co-ordinate, forming bonds to three non-bridging isopropoxide groups, and to two bridging oxygen atoms, one from each of the two ligands L.
