The syntheses of the three new guanidine-quinoline hybrid ligands TMGmqu, DMEGmqu and TMG t bqu are reported. Zinc chlorido and triflato complexes with these ligands were obtained and structurally characterised by X-ray crystallography. In the chlorido complexes the zinc atom is coordinated by two chlorido ligands and the bidentate guanidine ligand in a distorted tetrahedron. Using zinc triflate, tetrahedral bis(chelate) complexes are formed, and the triflate anions serve only for charge compensation. All reported complexes show activity in the polymerisation of rac-lactide, with the chlorido complexes only showing a poor activity. With the bis(chelate) triflato complexes a high polymerisation activity with a slight heterotactic bias was observed. Kinetic studies reveal a firstorder chain growth reaction for the lactide polymerisation with all complexes.
