Poly[[diaqua(?(2)-4,4'-dipyridyl sulfide-?N:N')(4,4'-dipyridyl sulfide-?N)(2-hydroxy-5-sulfonatobenzoato-?O)nickel(II)] dihydrate].

ABSTRACT: The asymmetric unit of the title helical coordination polymer, {[Ni(C(7)H(4)O(6)S)(C(10)H(8)N(2)S)(2)(H(2)O)(2)]·2H(2)O}(n), is comprised of an Ni(II) ion, one 5-sulfosalicylic acid dianion (HSSA), two 4,4'-dipyridylsulfide (4,4'-dps) ligands, and two coordinated and two uncoordinated water mol-ecules. The Ni(II) ion is coordinated by two water mol-ecules, one carboxyl-ate O atom of the HSSA dianion and three N atoms from three 4,4'-dps ligands in a distorted octa-hedral environment. Half of the 4,4'-dps ligands are ?(2)-bridging ligands which link adjacent Ni(II) centers, forming a one-dimensional helical structure along the b axis. This helical structure is further stabilized by O-H?O intra- and inter-molecular hydrogen bonds.

catena-Poly[4,4'-bipyridinium [[diaqua-disulfatocadmium(II)]-?-4,4'-bipyridine-?N:N'] dihydrate].

Project description:The title compound, {(C(10)H(10)N(2))[Cd(SO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), consists of anionic chains of the Cd complex, diprotonated 4,4'-bipyridinium cations and uncoordinated water mol-ecules. In the anionic chain, the Cd atom lies on a center of inversion in an octa-hedral geometry. The midpoint of the coordinated bipyridine also resides on a center of inversion, as does the non-coordinated bipyridinium counterion. O-H?O and N-H?O hydrogen bonding inter-actions and ?-? stacking inter-actions in the structure are responsible for the supra-molecular assembly.

Poly[[(2,2'-bipyridine)-(μ(3)-2-sulfonatobenzoato)lead(II)] dihydrate].

Project description:In the title compound, {[Pb(sbc)(bpy)]·2H(2)O}(n) [bpy is 2,2'-bipyridine (C(10)H(8)N(2)) and sbc is the 2-sulfonatobenzoate dianion (C(7)H(4)O(5)S)], the Pb(II) ion is bonded to four O atoms including carboxyl-ate and sulfonate from three sbc dianions, and two N atoms from a chelating 2,2'-bipyridine ligand. The sbc ligand acts as a μ(3)-bridging ligand by one O atom of the sulfonate group and the two O atoms of the carboxyl-ate. Of these two last O atoms, one builds up a dinuclear framework arranged around an inversion center whereas the second one links each dinuclear unit, forming a chain extending along the b axis. These polymeric chains are linked through O-H⋯O hydrogen bonds involving the water mol-ecules, forming a layer parallel to (10).

Project description:The title coordination polymer, [Ni(C(10)H(8)O(6))(C(10)H(8)N(2))(H(2)O)(2)](n), was obtained by the hydro-thermal reaction of nickel(II) sulfate, benzene-1,4-dioxy-diacetic acid (p-phenyl-enedioxy-diacetic acid) and 4,4'-bipyridine (4,4'-bpy) in alkaline aqueous solution.

The Ni(II) atom and benzene-1,4-dioxy-diacetate and 4,4'-bpy moieties lie on inversion centres.
