Abstract: | A polymeric heterometallic compound, {Gd2Zn3(C4H4O5)6(H2O)6]·12H2O}n, comprising zinc(II) and gadolinium(III) cations bridged by carboxylate groups from oxydiacetate ligands, is presented. The GdIII cations lie at sites with crystallographic 32 symmetry and display a tricapped trigonal‐prism arrangement, which is defined by six carboxyl and three ether O atoms. The ZnII cations lie at sites with imposed 2/m symmetry and are octahedrally coordinated by four carboxyl O atoms and two apical water ligands, which form strong intramolecular hydrogen bonds. Comparison is made with the previously reported isostructural homologous copper–gadolinium complex. |
