Description

General description

4′-Chloro-2,2′:6′,2′′-terpyridine (4′-Cltpy, Cltpy, Cl-terpy) is a tridentate ligand that contains a terpyridine (tpy) site with a Cl site at the 4 -position. It coordinates with various metal ions through these two sites to form different coordination polymers. Crystal structure study shows terpyridine unit of Cltpy adopts a trans, trans conformation. Mol­ecules assemble themselves into stacked columns along the b axis, with an inter­planar distance of 3.51Å. It undergoes Williamson type ether reactions with α,ω-bishydroxy-functionalized poly(propylene oxide). It undergoes Williamson type reaction with α-hydroxy-ω-carboxy-functionalized poly(ethylen-oxide) to afford monoterpyridine terminated telechelics.
