چکیده
The title coordination polymer, {[Cd(2)(C(8)H(4)O(5))(2)(C(14)H(8)N(4))(2)]·2H(2)O}(n), has a layered structure. The asymmetric unit contains two Cd(II) ions, two pyrazino-[2,3-f][1,10]phenanthroline, two 5-hy-droxy-isophthalate (hip) ligands and two lattice water mol-ecules. Each Cd(II) ion is coordinated by two N atoms from a chelating pyrazino-[2,3-f][1,10]phenanthroline and four O atoms from three different hip ligands, resulting in a distorted CdN(2)O(4) octa-hedral coordination environment. The hip ligand connects adjacent Cd(II) ions, forming forming layers parallel to (010). Intralayer O-H⋯O hydrogen bonds involving the hydroxy groups and solvent water molecules consolidate the crystal packing.

In the title compound, [Pb₂(C₇H₄O₆S)₂(C₁₂H₈N₂)₂(H₂O)₂]·CH₃COOH, the seven-coordinate Pb(II) atom is chelated by two N atoms of one 1,10-phenanthroline ligand, four O atoms from three 5-sulfosalicylate dianions and one water O atom. Each dianion serves as a bridging ligand, connecting adjacent Pb(II) atoms into a centrosymmetric polymeric chain extending parallel to [001]. There are π-π inter-ac...

In the title coordination polymer, [Cd₂(C₄H₄O₄)(NO₃)₂(C₁₂H₈N₂)₂(H₂O)₂](n), the Cd(II) ion is seven-coordinated within a distorted penta-gonal-bipyramidal O₅N₂ environment. The succinate anions, located on an inversion centre, adopt a bis-monodentate bridging mode, leading to the formation of rods along [100]. The rods are connected by O-H⋯O hydrogen bonds between the coordinating water mol-ecul...

The title copper coordination polymer, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(10)H(8)N(2))(2)](n), was synthesized by reacting Cu(NO(3))(2), isophthalic acid and 1,10-phenanthroline under hydro-thermal conditions. The trinuclear unit presents a central almost planar CuO(4) chromophore with the cation on a symmetry center, and two symmetry-related CuN(2)O(3) groups with the metal centre in a...

In the title polymer, [Pb(C(7)H(4)ClO(3))(2)(C(12)H(8)N(2))](n), the Pb(II) ion displays a distorted pseudo-octa-hedral coordination geometry. The metal center is coordinated by six O atoms from four 5-chloro-salicylate ligands and two N atoms from a chelating phenanthroline ligand. The polymeric structure is built up from bridging carboxyl-ate O atoms, forming chains along [100]. The crystal s...
