Poly[[?-aqua-bis-(?-4,4'-bipyridine-?N:N')bis-(?-3-hy-droxy-adamantane-1-carboxyl-ato-?O:O')bis-(3-hy-droxy-adamantane-1-carboxyl-ato-?O)dicobalt(II)] hepta-hydrate].

ABSTRACT: The title coordination compound, {[Co(C(11)H(15)O(3))(4)(C(10)H(8)N(2))(2)(H(2)O)]·7H(2)O}(n), consists of a pair of Co(II) atoms, four 3-hy-droxy-adamantane-1-carboxyl-ate anions (L), one water mol-ecule, two bridging 4,4'-bipyridine (4,4'-bpy) ligands and seven uncoordinated water mol-ecules. Both of the Co(II) ions are coordinated in a distorted octa-hedral geometry. Four L ligands bind to each pair of Co(II) atoms in a plane, two of which bridge the two Co(II) atoms as bidentate groups while the other two coordinate to a single Co(II) atom in a monodentate mode. Two half-mol-ecules of 4,4'-bipyridine coordinate the Co(II) atoms from the upside and underside. The packing features extensice O-H?O hydrogen bonding.

Project description:In the title coordination polymer, {[Zn(C(11)H(15)O(3))(2)(C(10)H(8)N(2))(C(11)H(16)O(3))]·H(2)O}(n), the Zn(II) ion is five coordinated by two N atoms from two 4,4'-bipyridine (4,4'-bpy) mol-ecules and three O atoms from two 3-hy-droxy-adamantane-1-carboxyl-ate anions (L) and one 3-hy-droxy-adamantane-1-carb-oxy-lic acid (HL) mol-ecule. The resulting coordination polyhedron is a near regular ZnN(2)O(3) trigonal bipyramid, with the N atoms in axial sites. The 4,4'-bpy mol-ecules [dihedral angle between the aromatic rings = 17.2?(2)°] act as bridges, connecting the metal ions into an infinite polymeric chain propagating in [[Formula: see text]01]. O-H?O hydrogen bonds help to consolidate the packing.

Poly[[nona-aqua-bis-(?-5-hy-droxy-benzene-1,3-di-carboxyl-ato)(5-hy-droxy-benzene-1,3-di-carboxyl-ato)dicerium(III)] hexa-hydrate].

Project description:In the title coordination polymer, {[Ce2(C8H4O5)3(H2O)9]·6H2O} n , the asymmetric unit is formed by two Ce(III) atoms, three 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands, nine coordinating water mol-ecules and six water mol-ecules of crystallization. The two Ce(III) atoms are bridged by 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands acting in a bis-bidentate coordination mode, generating infinite chains along [101]. Both independent metal atoms are nine-coordinated, one by four O atoms from the carboxyl-ate groups of two bridging 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands and five O atoms from water mol-ecules, generating a tricapped trigonal-prismatic geometry. The coordination around the second Ce(III) atom is similar, except that one of the water mol-ecules is replaced by an O atom from an additional 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligand acting in a monodentate coordination mode and forming a capped square-anti-prismatic geometry.

?-4,4'-Bipyridine-bis-[aqua-(4-hy-droxy-pyridine-2,6-dicarboxyl-ato)copper(II)].

Project description:The title compound, [Cu(2)(C(7)H(3)NO(5))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a centrosymmetric binuclear molecule. Each completely deprotonated 4-hy-droxy-pyridine-2,6-dicarb-oxy-lic acid mol-ecule assumes a tridentate chelating coordination mode. The square-pyramidal coordination geometry around the Cu(II) ion is completed by the bridging bipyridine ligand and an apical water molecule. Adjacent complexes are connected via O-H?O and C-H?O hydrogen bonds to generate a three-dimensional supra-molecular structure.

Bis(6'-carb-oxy-2,2'-bipyridine-6-carboxyl-ato-?N,N',O)nickel(II) tetra-hydrate.

Project description:In the title compound, [Ni(C(12)H(7)N(2)O(4))(2)]·4H(2)O, the Ni atom is located at the centre of a distorted octa-hedron, formed by four N atoms and two O atoms from the same two tridentating chelated 6-carb-oxy-2,2'-bipyridine-6'-carboxyl-ate (L) ligands. Face-to-face ?-stacking inter-actions between inversion-related pyridine rings with centroid-centroid distances of 3.548?(3) and 3.662?(3)?Å (perpendicular distances between the respective rings are 3.314 and 3.438?Å) are found. Inter-molecular O-H?O hydrogen bonds between water mol-ecules and L ligands form R(5) (3)(10), R(6) (5)(14) and R(5) (5)(12) rings and also a centrosymmetric cage-like unit of water mol-ecules, which link eight adjacent Ni(II) centers, forming a three-dimensional framework.

Poly[[hepta-?(2)-aqua-bis-(?(2)-pyrazine-2-carboxyl-ato)dibarium] bis-(pyrazine-2-carboxyl-ate)].

Project description:In the layered title coordination polymer, {[Ba(2)(C(5)H(3)N(2)O(2))(2)(H(2)O)(7)](C(5)H(3)N(2)O(2))(2)}(n), the coordination geometries around the two independent Ba(II) ions can be described as bicapped square-anti-prismatic [BaNO(9)] arrangements. A two-dimensional polymeric framework with (6,3) topology can be observed in the ac plane, the nodes being provided by Ba(II) ions and the connectors being N and O atoms belonging to pyrazine-2-carboxyl-ate ligands and O atoms of bridging water mol-ecules. Non-coordinating pyrazine-2-carboxyl-ate ions are located between the polymeric layers in the crystal and are interconnected through extensive O-H?N,O hydrogen bonding.

Project description:The asymmetric unit of the title coordination polymer, {[Gd(2)(C(8)H(4)O(5))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)]·3H(2)O}(n), contains two Gd(III) cations, one of which is surrounded by three 5-hy-droxy-isophthalate anions, one 2,2'-bipyridine ligand and two water mol-ecules in a distorted N(2)O(7) tricapped trigonal-prismatic coordination geometry. The other Gd cation is coordinated by four 5-hy-droxy-isophthalate anions and one 2,2'-bipyridine ligand in a distorted N(2)O(7) tricapped trigonal-prismatic coordination geometry. The 5-hy-droxy-isophthalate anions bridge the Gd cations, forming a layer structure. The layers are further connected by extensive O-H?O hydrogen bonding, assembling a three-dimensional supra-molecular network.

Project description:In the title dinuclear complex, [Tm(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, the Tm(III) atoms are coordinated by eight O atoms from four 2-(4-hy-droxy-phen-yl)acetate (HPAA) ligands and a water mol-ecule, and one N atom from a 4,4'-bipyridine ligand in a distorted tricapped trigonal-prismatic geometry. While four of the HPAA ligands coordinate to just one Tm atom, the remaining two HPAA ligands bridge the two Tm atoms. In the crystal, O-H?O and O-H?N hydrogen bonds link the mol-ecules into a three-dimensional network.
