Poly[diammonium [(?(4)-butane-1,2,3,4-tetra-carboxyl-ato)zincate] tetra-hydrate].

ABSTRACT: In the title compound, {(NH(4))(2)[Zn(C(8)H(6)O(8))]·4H(2)O}(n), the asymmetric unit contains one ammonium cation, half of a butane-1,2,3,4-tetra-carboxyl-ate anion, one Zn(2+) cation and two water mol-ecules. The butane-1,2,3,4-tetra-carboxyl-ate ligand is located about an inversion centre at the mid-point of the central C-C bond. The Zn(2+) cation is situated on a twofold rotation axis and is surrounded by four O atoms from four symmetry-related butane-1,2,3,4-tetra-carboxyl-ate anions in a distorted tetra-hedral environment. In turn, each anion coordinates to four Zn(2+) cations. The bridging mode of the anions leads to a three-dimensional framework structure with channels extending along [110] and [010] in which the ammonium cations and the water mol-ecules are located. N-H?O and O-H?O hydrogen bonding between the cations and water mol-ecules and the uncoordinating O atoms of the carboxyl-ate groups consolidates the crystal packing.

Project description:The asymmetric unit of the title Mn(II) coordination polymer, {[Mn(2)(C(8)H(6)O(8))(H(2)O)(3)]·H(2)O}(n), contains two crystallographic-ally independent Mn(II) cations, two half butane-1,2,3,4-tetra-carboxyl-ato anions, each lying on a centre of inversion, and four water mol-ecules.

The other Mn centre is coordinated by five carboxyl-ate O atoms from four different anions and one water O atom. One water mol-ecule does not coordinate to a Mn centre. The crystal packing is stabilized by several O-H?O hydrogen bonds, forming a three-dimensional framework.

Project description:The asymmetric unit of the title compound, [Ni(2)(C(8)H(6)O(8))(C(12)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains a half of the centrosymmetric dinuclear complex mol-ecule and three uncoordinated water mol-ecules.

Each Ni(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, one O atom from the BTC(4-) anion and three aqua ligands in a distorted octa-hedral geometry. Inter-molecuar O-H?O hydrogen bonds and ?-? stacking inter-ations [centroid-centroid distances = 3.646?(2), 3.781?(2) and 3.642?(2)?Å] consolidate the crystal packing.

Poly[triaqua-(?-butane-1,2,3,4-tetra-carboxyl-ato)dicadmium(II)].

Project description:The asymmetric unit of the title Cd(II) coordination polymer, [Cd(2)(C(8)H(6)O(8))(H(2)O)(3)](n), contains two crystallographically independent Cd(II) cations, one-half each of two independent anionic butane-1,2,3,4-tetra-carboxyl-ate units (L) and three water mol-ecules. Both anionic units lie on inversion centers. One of the Cd(II) ions is six-coordinated by four carboxyl-ate O atoms from four L anions and two water O atoms in a distorted octa-hedral coordination environment. The other Cd(II) ion is eight-coordinated by seven carboxyl-ate O atoms from four L anions and one water O atom. The anionic units bridge neighboring Cd(II) centers, forming a three-dimensional framework. O-H?O hydrogen-bonding inter-actions between the water mol-ecules and carboxyl-ate O atoms further stabilize the structure.

Project description:There are three independent Cd(II) ions in the title complex, {[Cd(3)(C(10)H(3)O(8))(2)(H(2)O)(4)]·4H(2)O}(n), one of which is coordinated by four O atoms from three 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands and by two water mol-ecules in a distorted octa-hedral geometry. The second Cd(II) ion is coordinated by five O atoms from four 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands and by one water mol-ecule also in a distorted octa-hedral geometry while the third Cd(II) ion is coordinated by five O atoms from three 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands and by one water mol-ecule in a highly distorted octa-hedral geometry. The 5-carboxybenzene-1,2,4-tri-carboxyl-ate ligands bridge the Cd(II) ions, resulting in the formation of a three-dimensional structure. Intra- and inter-molecular O-H?O hydrogen bonds are present throughout the three-dimensional structure.

Acridinium (6-carboxy-pyridine-2-carboxyl-ato)(pyridine-2,6-dicarboxyl-ato)zincate(II) penta-hydrate.

Project description:The reaction of Zn(NO(3))(2) with pyridine-2,6-dicarboxylic acid (pydcH(2)) and acridine (acr) in aqueous solution leads to the formation of the title compound, (C(13)H(10)N)[Zn(C(7)H(3)NO(4))(C(7)H(4)NO(4))]·5H(2)O or (acrH)[Zn(pydcH)(pydc)]·5H(2)O. In the title compound, the Zn(II) atom is coordinated by four O atoms and two N atoms from the tridentate chelating rings of (pydc)(2-) and (pydcH)(-) anions. The geometry of the resulting ZnN(2)O(4) coordination can be described as distorted octa-hedral. To balance the charges, one protonated acridine (acrH)(+) cation is present. In the crystal structure, extensive O-H?O and N-H?O hydrogen bonds involving acrH(+), the complex anion and uncoordinated water mol-ecules form a three-dimensional network.

Poly[[tetra-aqua-tris-(?(3)-hexane-1,6-di-carboxyl-ato)diterbium(III)] 0.25-hydrate].

Project description:In the title terbium coordination polymer, {[Tb(2)(C(6)H(8)O(4))(3)(H(2)O)(4)]·0.25H(2)O}(n), the Tb(III) atom is nine-coordinated, forming a TbO(9) polyhedra. Furthermore, two symmetric TbO(9) polyhedra share their edges, forming Tb(2)O(16) dimers, which are linked by adipate bridges into a layered structure. Inter-molecular O-H?O hydrogen bonds link these layers into a three-dimensional network. One of the C atoms of the adipate ligand is disordered over two positions with site-occupancy factors of 0.622?(9) and 0.378?(9). The structure also contains a disordered mol-ecule of water of hydration, lying close to a special position, with partial occupancy.

Propane-1,3-diammonium bis-[aqua-chlorido(4-hydroxy-pyridine-2,6-di-carboxyl-ato-κO,N,O)mercurate(II)] tetra-hydrate.

Project description:The reaction of mercury(II) chloride dihydrate, propane-1,3-diamine and 4-hydroxy-pyridine-2,6-dicarboxylic acid in a 1:1:1 molar ratio in aqueous solution, resulted in the formation of the title compound, (C(3)H(12)N(2))[Hg(C(7)H(3)NO(5))Cl(H(2)O)](2)·4H(2)O or (pnH(2))[Hg(hypydc)Cl(H(2)O)](2)·4H(2)O (where pn is propane-1,3-diamine and hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid). The metal atom is coordinated by one chloride group, one water mol-ecule cis to the chloride ligand and one (hypydc)(2-) ligand. The coordinated water mol-ecule is almost perpendicular to the plane of the aromatic ring of (hypydc)(2-). The geometry of the resulting HgClNO(3) coordination can be described as distorted square-pyramidal. This structure also contains propane-1,3-diammonium (site symmetry 2) as a counter-ion and four uncoordinated water mol-ecules. There is a wide range of non-covalent inter-actions consisting of hydrogen bonding [of the types O-H⋯O, N-H⋯O and C-H⋯O, with D⋯A ranging from 2.548 (5) to 3.393 (6) Å] and ion pairing.

Poly[(?-benzene-1,2,4,5-tetra-carboxyl-ato)tetra-silver(I)].

Project description:In the centrosymmetric title compound, [Ag(4)(C(10)H(2)O(8))](n), the benzene ring has irregular bond lengths but remains planar (r.m.s. deviation 0.0002?Å). The Ag-O bond lengths are in the range 2.153?(3)-2.615?(4)?Å. The carboxyl-ate groups are oriented at dihedral angles of 26.4?(5) and 74.9?(4)° to the benzene ring. The coordination behaviour of each carboxyl-ate O atom is different: in one carboxylate, the O atoms are coordinated to a single and two Ag atoms; in the other carboxylate, the O atoms are coordinated to two and three Ag atoms. Non-classical inter-molecular C-H?O hydrogen bonding is present in the crystal structure. The title compound forms a three-dimensional polymeric network due to the coordination of the Ag atoms.

Poly[[octaaqua-?4-(benzene-1,2,4,5-tetra-carboxyl-ato)-dicobalt(II)] octa-hydrate].

Project description:The title polymeric coordination compound, {[Co2(C10H2O8)(H2O)8]·8H2O} n , was obtained by slow diffusion of a dilute aqueous solution of CoCl2 and the sodium salt of benzene-1,2,4,5-tetracarboxylic acid (H4btec) through an agar-agar gel bridge in a U-shaped tube. The two independent Co(2+) ions are each situated on an inversion centre and are coordinated in a slightly distorted octa-hedral geometry by four water O atoms and two carboxyl-ate O atoms from two btec(4-) ligands (-1> symmetry), forming a layer parallel to (11-1). This layer can be described as a mol-ecular two-dimensional square grid with the benzene rings at the nodes and the Co(II) atoms connecting the nodes. O-H?O hydrogen-bonding interactions involving the coordinating water molecules, the carboxylate O atoms and lattice water molecules lead to the formation of a three-dimensional network.
