Abstract
In the title compound, {[Dy(C(8)H(6)NO(4))(H(2)O)(5)]Cl(2)·H(2)O} (n) the central Dy(III) atom is nine-coordinated by four oxygen atoms from two symmetry-related chelating carboxyl-ate groups and five water mol-ecules, resulting in a distorted polyhedral geometry best described as 'muffin'-type by continuous shape measure analysis. The bridging ligands generate infinite [10] chains and the structure is consol-idated by an extensive hydrogen-bonding network and weak π-π stacking inter-actions.
