Abstract:
Two bismuth(III) complexes {[Bi(btx) 0.5 Cl 4 ](Hbtx)} n ( 1 ) and [Bi 2 (Fbtx)Cl 10 ](H 2 Fbtx) 2 (MeOH) ( 2 ) based on the nonfluorinated ligand 1,4‐bis[(1,2,4‐triazole‐1‐yl)methyl] benzene (btx) or the perfluorinated analogue 1,4‐bis[(1,2,4‐triazole‐1‐yl)methyl] ‐2,3,5,6‐benzene (Fbtx) were synthesized and characterized. Single‐crystal X‐ray diffraction revealed that 1 is a coordination polymer consisting of an anionic one‐dimensional chain, whereas 2 shows a discrete ionic‐paired structure. Furthermore, 1 was found to be more active than 2 toward the bulk solvent‐free polymerization of glycolide, giving poly(glycolic acid) (PGA) with high molecular weights and moderate molecular weight distributions. The results indicated that the substituent effect plays an important role in controlling the structure and catalytic activity of such complexes.
