2D and 3D Zn(II) coordination polymers based on 4′-(Thiophen-2-yl)-4,2′:6′,4′'-terpyridine: Structures and features of sorption behavior

Reactions of Zn(II) nitrate, 4′-(Thiophen-2-yl)-4,2′:6′,4′'-terpyridine (ThioTerPy) and terephtalic (bdc) or 2-iodoterephtalic (2-I-bdc) acids result in 2D coordination polymer [Zn2bdc(ThioTerPy)2(OH)2] (1) or 3D metal-organic framework [Zn(2-I-bdc)(ThioTerPy)] (2), respectively. Both compounds were characterized by X-ray diffractometry. For 2, I2 absorption, as well as selectivity of sorption of different organic substrates from mixtures was studied. © 2022 Elsevier B.V.
