| Summary: | In the title coordination polymer, {[Tm(C7H2NO5)(H2O)3]·H2O}n, the TmIII atom is eight-coordinated by a tridentate 4-oxidopyridine-2,6-dicarboxylate trianion, two monodentate anions and three water molecules, forming a distorted bicapped trigonal–prismatic TmNO7 coordination geometry. The anions bridge adjacent TmIII ions into double chains. Adjacent chains are further connected into sheets. O—H...O hydrogen bonds involving both coordinated and uncoordinated water molecules generate a three-dimensional supramolecular framework. |
