Abstract: The title samarium(III) coordination polymer, [Sm(C₆H₄NO₂)(C₇H₃NO₄)(H₂O)₂]_n, has a pyridine-3,4-dicarboxylate-bridged ribbon structure. The isonicotinate (ina) anion chelates to the water-coordinated metal atom, which shows ninefold coordination. The ina unit arises from the decarboxylation of pyridine-3,4-dicarboxylic acid under the hydrothermal conditions of the synthesis.
