چکیده

The asymmetric unit of the title compound, [Li(3)(C(6)H(5)N(2)O(2))(2)(NO(3))(H(2)O)(2)](n) contains three Li(I) ions, two ligand anions, two water mol-ecules and a nitrate anion. Related by a centre of inversion, they form a centrosymmetric mol-ecular cluster in which one of the Li(I) ions shows trigonal-bipyramidal and the other two distorted tetra-hedral coordination. Li(I) ions are bridged by water O atoms and carboxyl-ate O atoms donated by one of the ligands. The clusters, bridged by two nitrato O atoms, form mol-ecular columns along [010], which are held together by O-H⋯O and O-H⋯N hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.694 (1) and 3.796 (1) Å].

In the title coordination polymer, [PbBr(C(6)H(5)N(2)O(2))(H(2)O)](n), the Pb(II) atom is coordinated by one pyrazine N atom, two bridging Br atoms, a water mol-ecule and three carboxyl-ate O atoms. Bridging by the two anions generates a layer structure parallel to (001); the layers are linked by O-H⋯N and O-H⋯Br hydrogen bonds, forming a three-dimensional network. The lone pair is stereochemic...

The title compound, [Sn(4)(C(8)H(17))(8)O(2)(C(6)H(5)N(2)O(2))(4)], is a tetra-nuclear Sn(IV) complex, built up by inversion symmetry around the central Sn(2)O(2) ring. The Sn(IV) coordination geometries are distorted SnO(3)C(2) trigonal-bipyramidal and distorted SnO(4)C(2) octa-hedral. The three-coordinate μ(3)-oxido bridging O atom in the Sn(2)O(2) ring is attached to three Sn atoms. All non-...
