Abstract: The title dysprosium coordination polymer [Dy(IN)₃(H₂O)₂]_n, where IN^- is the isonicotinate anion C₆H₄NO₂^-, has been hydrothermally synthesized. The polymer exhibits a doubly carboxylate-bridged infinite chain-like structure with the metal center lying on a crystallographic twofold axis and coordinating by two carboxylate O atoms from a chelating isonicotinate group (also lying on a twofold axis), four carboxylate O atoms from four bridging isonicotinate ligands, and two water molecules, to yield an eight-coordinate square-antiprismatic geometry.
