摘要
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.
