Two novel bismuth succinate hydrates, namely, poly[[diaqua(μ₃-butane-1,4-dicarboxylato)hemi(μ-butane-1,4-dicarboxylato)bismuth] monohydrate], {[Bi(C₄H₄O₄)_1.5(H₂O)₂]·H₂O}_n (1), and poly[[μ-aqua-aqua(μ₃-butane-1,4-dicarboxylato)(μ-butane-1,4-dicarboxylato)-μ-oxido-dibismuth] monohydrate], {[Bi₂(C₄H₄O₄)₂O(H₂O)₂]·H₂O}_n (2), have been synthesized. Their crystal structures were determined by single-crystal X-ray diffraction and the compounds were characterized by IR and Raman spectroscopy, powder X-ray diffraction and thermal analysis. The crystal structure analysis revealed that the compounds are coordination polymers, with 1 having a two-dimensional layered structure and 2 displaying a three-dimensional (3D) framework. Fully deprotonated succinate anions (C₄H₄O₄²⁻) in two different conformations (trans and gauche) are included in their composition. The Bi³⁺ cations are surrounded by O atoms from the carboxylate groups of succinate anions and aqua ligands. BiO₉ coordination polyhedra in 1 are connected in pairs by edges. These pairs are bound together by bridging succinate ligands to form layers. Bismuth coordination polyhedra of two different types (BiO₉ and BiO₇) in 2 are connected by edges to form infinite ribbons. Ribbons of polyhedra with bridging succinate ligands form a 3D polymeric structure.
