Syntheses and crystal structures of the cerium-based coordination polymers poly[(acetic acid)bis-(μ-5-carb-oxy-thio-phene-2-carboxyl-ato)bis-(μ-thio-phene-2,5-di-carboxyl-ato)dicerium(III)] and poly[(μ-acetato)-aqua-(μ₄-thio-phene-2,5-di-carboxyl-ato)cerium(III)].

ABSTRACT: The title compounds, [Ce₂(C₆H₃SO₄)₂(C₆H₂SO₄)₂(CH₃COOH)] _n (1) and [Ce(CH₃COO)(C₆H₂SO₄)(H₂O)] _n (2) were synthesized by solvothermal reaction of Ce(NO₃)₃·6H₂O with 2,5-thio-phenedi-carb-oxy-lic acid (H₂TDC, C₆H₄SO₄) and acetic acid in aceto-nitrile or ethanol/water, respectively. These compounds were obtained as single crystals among other crystalline phases. Both compounds belong to the family of three-dimensional coordination polymers. The asymmetric unit of 1 consists of two Ce^III ca
