Catena-Poly[[[bis-[μ-3-(4-carb-oxy-phen-oxy)propionato]-κO,O:O;κO:O,O-bis-[aqua-(N,N-dimethyl-formamide-κO)cadmium]]-μ-4,4'-bipyridine-κN:N'] dinitrate].

ABSTRACT: In the title coordination polymer, {[Cd(2)(C(10)H(9)O(5))(2)(C(10)H(8)N(2))(2)(C(3)H(7)NO)(2)(H(2)O)(2)](NO(3))(2)}(n), the 3-(4-carb-oxy-phen-oxy)propionate monoanion O,O'-chelates to a Cd(II) cation through the aliphatic carboxyl-ate end. One of these O atoms is also connected to the metal cation from an inversion-related metal atom. The five O atoms bonded to the metal centre form a penta-gon, above and below which are located the N atoms of the 4,4'-bipyridine mol-ecules. The polycationic ribbon propagates along the b axis of the unit cell. The (aromatic) carboxyl end of the monoanion connects adjacent ribbons into a layer motif in the (102) plane. The nitrate ions are hydrogen bonded to the layer. The geometry of the Cd(II) atom is a trans-N(2)O(5)Cd penta-gonal bipyramid.

Project description:The polymeric title compound, {[Bi(C(9)H(4)O(6))(NO(3))(C(10)H(8)N(2))(C(2)H(6)OS)]·C(2)H(6)OS}(n), was obtained by the reaction of bis-muth(III) nitrate, bipyridine (bpy) and 1,3,5-benzene-tricarb-oxy-lic acid (H(3)BTC).

The crystal packing is stabilized by O-H⋯O and C-H⋯O hydrogen bonds. The S atom of the non-coordinating dimethyl sulfoxide mol-ecule is disordered over two sets of sites with refined site-occupancies of 0.430 (19) and 0.570 (19).

μ-4,4'-Bipyridine-κN:N'-bis-[aqua-(4,4'-bi-pyridine-κN)(l-valinato-κN,O)copper(II)] dinitrate dihydrate.

Project description:In the title dinuclear complex, [Cu(2)(C(5)H(10)NO(2))(2)(C(10)H(8)N(2))(3)(H(2)O)(2)](NO(3))(2)·2H(2)O, each of the two l-valinate anions chelates a Cu(II) center through the amino N and carboxyl-ate O atom, forming a five-membered ring. A 4,4'-bipyridine mol-ecule bridges two water-coordinated Cu atoms, each of which is connected to another 4,4'-bipyridine, giving rise to a square-pyramidal coordination geometry for the Cu(II) centers. The dinuclear dications, nitrate anions and uncoord-inated water mol-ecules are linked into a two-dimensional structure.

Poly[triaqua-[μ(4)-3-(4-carboxyl-atophen-oxy)propionato-κO:O':O'':O'''][μ(3)-3-(4-carboxyl-atophen-oxy)propionato-κO:O':O'']dizinc].

Project description:The coordination polymer [Zn(2)(C(10)H(8)O(5))(2)(H(2)O)(3)](n) adopts a layer structure in which the two independent Zn(II) ions exist in trigonal-bipyramidal coordination geometries. One carboxyl-ate dianion binds to a monoaqua-coordinated metal ion through the aliphatic carboxyl-ate end and to the diaqua-coordinated metal ion through the aromatic carboxyl-ate end; the other dianion binds in the reverse manner. Three of the four carboxyl-ate ends of the two dianions are also engaged in bridging inter-actions; these lead to a layer structure parallel to (100). Adjacent layers are linked by O-H(water)⋯O hydrogen bonds into a three-dimensional network.

Project description:The title compound, [Cu(C(8)H(7)O(3))(2)(C(10)H(8)N(2))]·H(2)O, is comprised of a Cu(II) ion, two 3-meth-oxy-benzoate ligands, a 2,2'-bipyridine (bipy) ligand and one uncoordinated water mol-ecule. The Cu(II) ion and the water O atom lie on a twofold axis. The Cu(II) ion exhibits a six-coordinate distorted octa-hedral geometry, with two N atoms from the bipy ligand [Cu-N = 1.9996 (16) Å] and four O atoms from two 3-meth-oxy-benzoate ligands [Cu-O = 1.9551 (15) and 2.6016 (16) Å]. The mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.

Tetra-aqua-(2,2'-bipyridine-κN,N')manganese(II) di-μ-aqua-bis-[aqua-(2,2'-bipyridine-κN,N')(5-sulfonatoisophthalato-κO)manganate(II)] tetra-hydrate.

Project description:The crystal structure of the title salt, [Mn(C(10)H(8)N(2))(H(2)O)(4)][Mn(2)(C(8)H(3)O(7)S)(2)(C(10)H(8)N(2))(2)(H(2)O)(4)]·4H(2)O, consists of mononuclear manganese(II) cations, dinuclear manganate(II) dianions and uncoordinated water mol-ecules. The dianion is located about an inversion center; the Mn(II) atom is coordinated by a 2,2'-bipyridine ligand, a sulfonatoisophthalate group, a water mol-ecule along with two bridging water mol-ecules in an octa-hedral geometry. The cation lies on a twofold rotation axis; the Mn(II) atom is coordinated by four water mol-ecules and a chelating 2,2'-bipyridine ligand in a distorted octa-hedral geometry. A partially overlapped arrangement between the bipyridine ligands and the aromatic ring of the sulfoisophthalate group of adjacent anions is observed; the distance (3.357 Å) indicates π-π stacking. Hydrogen bonds, with the water mol-ecules serving as hydrogen-bond donors, lead to a three-dimensional network architecture.
