One sodium cation is bonded to four water O atoms and one vanillinate O atom in a distorted square-based pyramidal arrangement; the other Na+ ion is six-coordinated by four water O atoms and two vanillinate O atoms in an irregular geometry. One of the vanillinate anions is directly bonded to two sodium ions, whilst the other only interacts with the polymeric network by way of hydrogen bonds. In the crystal, a two-dimensional polymeric array is formed; this is reinforced by O—H⋯O hydrogen bonds, which generate R               2               1(6) and R               2               2(20) loops.In the title coordination polymer, {[Na DOI: 10.1107/S1600536810000711/hb5277Isup2.hkl            Structure factors: contains datablocks I.

The CuI atom is coordinated by four N atoms from two bidentate chelating phen ligands in a distorted tetrahedral geometry. The hexatungstate anion, lying on an inversion center and possessing the well known Lindqvist structure, is formed by six edge-sharing WO6 octahedra, thus exhibiting an approximate hO symmetry. Three kinds of O atoms exist in the hexatungstate, viz. terminal Oa, bridging Ob and central Oc atoms. Besides the electrostatic effects between the anions and cations, weak C—H⋯O hydrogen bonds exist between the phen ligands and Oa or Ob atoms. The mean interplanar distances of 3.485 (1) and 3.344 (1) Å indicate π–π stacking interactions between neighboring phen ligands. These weak hydrogen bonds and π–π stacking interactions lead to a two-dimensional network.The title compound, [Cu(C DOI: 10.1107/S1600536809020170/hy2197Isup2.hkl            Structure factors: contains datablocks I.

The PbII atom is chelated by acetate and substituted quinolin-8-olate anions; the O atoms of the quinolin-8-olates also bridge to confer a five-coordinate status to each metal center. The geometry approximates a distorted Ψ-fac octahedron in which one of the sites is occupied by a stereochemically active lone pair.The molecule of the title compound, [Pb DOI: 10.1107/S1600536809003559/tk2365Isup2.hkl            Structure factors: contains datablocks I.

The Cu atom lies at the centre of a triangle formed by the coordination of three monodentate groups, viz. two thiosemicarbazide ligands and one NCS− anion. Weak intermolecular N—H⋯S interactions generate a two-dimensional network.In the title complex, [Cu(CH DOI: 10.1107/S1600536808013068/bg2183Isup2.hkl            Structure factors: contains datablocks I.
