Abstract By changing the ancillary ligands, three new zinc-based coordination polymers (CPs), [Zn(4,4′-bpy)(H2O)4]·(TDC)·(H2O)}n (1), [Zn(2,2′-dmbpy)(TDC)]n (2), and [Zn2(3,3′-dmbpy)(TDC)2]n (3) (H2TDC =2,5-thiophenedicarboxylic acid, 4,4′-bpy =4,4′-bipyridine, 2,2′-dmbpy =2,2′-dimethyl-4,4′-bipyridine, 3,3′-dmbpy =3,3′-dimethyl-4,4′-bipyridine) have been synthesized under the same reaction conditions
