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.
Three new supramolecular complexes, [Zn(dpds)(C6H5COO)2] n (1), [Zn(dpds)(C7H7COO)2] n (2), and [{Zn(dpds)[C6H4(COO)2]} · H2O] n (3) (dpds = 4,4′-dipyridyldisulfide, C6H5COOH = benzoic acid, C7H7COOH = m-methylbenzoic acid, C6H4(COOH)2 = phthalic acid), have been synthesized by using the flexible ligand 4,4′-dipyridyldisulfide (dpds) with benzoic acid, m-methylbenzoic acid, and phthalic acid. The [Zn(C6H5COO)2] moieties in 1 are connected by dpds to generate a 1-D helical chain. In 2, the [Zn(C7H7COO)2] moieties are bridged by two dpds ligands of different chiralities to form a discrete achiral macrocycle chair-like structure. The ZnN2O2 tetrahedra in 3 are alternately linked by a pair of dpds and phthalato ligands to form a 1-D double-stranded chain, which are assembled via S ··· S weak interactions into a 2-D layer. The resulting 2-D layers are inclined parallel into 3-D supramolecular architecture.
