چکیده
The title compound, [Li(C(5)H(4)N(3)O(2))(H(2)O)](n), is composed of centrosymmetric dinuclear units, in which the Li(I) ions are bridged by two carboxyl-ate O atoms donated by two ligands. The dinuclear unit is nearly planar [r.m.s. deviation = 0.0125 (2) Å]. The Li(I) ion is coordinated by an N,O-chelating ligand, a bridging carboxyl-ate O atom from another ligand and two bridging water O atoms in a distorted trigonal-bipyra-midal geometry. The water O atoms bridge the dinuclear units into a polymeric mol-ecular column along [010]. The columns are held together by O-H⋯O and N-H⋯N hydrogen bonds. An intra-molecular N-H⋯O inter-action also occurs.

In the title polymeric complex, [Ni(C(2)H(6)NO(3)S)(2)](n), the Ni(II) ion occupies a special position on an inversion centre and displays a slightly distorted octa-hedral coordination geometry, being linked to four sulfonate O atoms and to two N atoms of the taurine ligands. The sulfonate groups doubly bridge symmetry-related Ni(II) centers, forming polymeric chains along the a axis.

The title compound [Cu(2)(C(6)H(3)BrNO(2))(4)](n), forms sheets in the bc plane. The structure features the dinuclear paddle-wheel cage motif common to copper(II) carboxyl-ates. The polymeric structure is achieved through bridging between binuclear units by the pyridyl donors of two of the four carboxyl-ates of the cage. Each cage engages in axial bonding at each copper atom to a pyridyl nitro-...
