Synthesis and X-ray crystal structure of the dimeric compound [C16H16N2O2Ti(BH3)2]2, a dimer of NN′-ethylenebis(salicylidenaminato)titanium containing seven-co-ordinate titanium(IV) and amino-borane as donor groups

Abstract

The reaction of dichloro-NN′-ethylenebis(salicylidenaminato)titanium(IV), [Ti(salen)Cl₂], with lithium tetrahydroborate gave, via addition of BH₄^– to the imino-functions of the ligand, a dimeric seven-co-ordinate titanium(IV) compound containing amine-boranes as donor groups; its crystal and molecular structure together with spectroscopic data are reported.
