Cover Story: The word “terpyridine” is synonymous with the chelating ligand 2,2′:6′,2″-tpy. However, another 47 isomers of terpyridine can be drawn, and 3,2′:6′,3″-tpy is one isomer that is suited to the assembly of coordination polymers. The 3,2′:6′,3”-tpy unit offers three possible planar conformations and with this conformational change comes a change in the vectorial properties of the outer pyridine donors. In this paper, the 3,2′:6′,3”-tpy is functionalized in the 4'-position with a 1,1'-biphenyl group, which bears a 4'-X group (X = H, F, Cl, Br, Me). In [Cu2(μ-OAc)4L]n 1D-coordination polymers (L is a 3,2′:6′,3”-tpy), the increased steric demands of H or F versus Cl, Br, or Me group induce a conformational switch of the 3,2′:6′,3”-tpy metal-binding domain, and a concomitant change in dominant packing interactions.
