Poly[[triaqua-(?(3)-pyridine-2,4,6-tricarboxyl-ato)terbium(III)] monohydrate].


ABSTRACT: The asymmetric unit of the title compound, {[Tb(C(8)H(2)NO(6))(H(2)O)(3)]·H(2)O}(n), contains one Tb(III) ion, one pyridine-2,4,6-tricarboxyl-ate (ptc) anion, three aqua ligands and one lattice water mol-ecule. The Tb(III) ion is nine coordinated by one N and five O atoms from three ptc ligands and by three O atoms from the three aqua ligands in a distorted bicapped trigonal-prismatic geometry. The ptc ligands bridge the Tb(III) ions into a two-dimensional polymeric framework parallel to (100). An extensive O-H?O hydrogen-bonding network consolidates the crystal packing.
