Abstract

A range of titanium compounds containing the naturally occurring dyes quinizarin (QH₂) and alizarin (AH₂) was synthesized and structurally characterized in the solid state. Among these is the first examples of a discrete metallocyclic arrangement formed exclusively using quinizarin ligands and the first examples of lanthanide containing titanium compounds of the alizarin family of ligands.
