Poly[?-aqua-aqua-(?-benzene-1,2,4,5-tetra-carboxyl-ato)gadolinate(III)potassium(I)].

ABSTRACT: In the title compound, [KGd(C(10)H(2)O(8))(H(2)O)(2)](n), the Gd(3+) ion is nine-coordinated by eight O atoms from five individual benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligands and one water mol-ecule, and the K(+) ion is eight-coordinated by six O atoms from five individual btec ligands and two water mol-ecules. In the crystal, the btec half-mol-ecules are completed by crystallographic inversion symmetry. GdO(9) and KO(8) polyhedra are connected, forming layers in the ab plane, which are further inter-connected by ?(8)- or ?(12)-bridging btec ligands, forming a three-dimensional structure.

Project description:The asymmetric unit of the title compound, {[Zn(2)(C(10)H(2)O(8))(H(2)O)(6)]·2H(2)O}(n), contains two distinct Zn atoms joined by a bridging water molecule and two bridging carboxyl-ate groups belonging to distinct halves of benzene-1,2,4,5-tetra-carboxyl-ate (tbec) tetra-anionic ligands, both lying on crystallographic inversion centres. The structure of this new isopolymorphic one-dimensional coordination polymer features asymmetric bimetallic octa-hedral knots. O-H?O hydrogen bonds between water molecules and carboxylate O atoms help to consolidate the crystal packing.

Poly[(μ-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.

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

Poly[[hexa-μ-aqua-diaqua-bis-(μ₄-dihydrogen benzene-1,2,4,5-tetra-carboxyl-ato)magnesiumdisodium] dihydrate].

Project description:The asymmetric unit of the title compound, {[MgNa₂(C₁₀H₄O₈)₂(H₂O)₈]·2H₂O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (-Na-Na-Mg-)(n) chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by μ₄-bridging btec ligands, which form inter-molecular O-H⋯O hydrogen bonds to uncoordinated water mol-ecules and the coordinated water mol-ecules of a neighbouring chain. In each btec ligand, there are also intramolecular O-H⋯O hydrogen bonds.

Poly[[diaqua-(μ(8)-benzene-1,2,4,5-tetra-carboxyl-ato)calciumzinc] monohydrate].

Project description:In the title complex, {[CaZn(C(10)H(2)O(8))(H(2)O)(2)]·H(2)O}(n), the Zn(II) ion is coordinated by four O atoms from four benzene-1,2,4,5-tetra-carboxyl-ate anions in a distorted tetra-hedral geometry. The Ca(II) ion is eight-coordinated by six O atoms from four benzene-1,2,4,5-tetra-carboxyl-ate anions and by two water mol-ecules in a distorted square-anti-prismatic geometry. The Ca(II) and Zn(II) ions and the lattice water mol-ecule are located on twofold rotation axes; the centroid of the benzene-1,2,4,5-tetra-carboxyl-ate anion is located on a centre of inversion. The μ(8)-bridging mode of the anion results in the formation of a three-dimensional structure with channels extending along [100] in which lattice water mol-ecules are situated. Inter-molecular O-H⋯O hydrogen bonds involving the coordinating and lattice water mol-ecules as donors and the carboxyl-ate O atoms and lattice water mol-ecules as acceptors are present in the structure.

Project description:The asymmetric unit of the polymeric title compound, {[Cu2(C10H2O8)(C3H4N2)4(H2O)2]·C3H7NO} n , contains two independent Cu(II) ions, each coordinated by one water mol-ecule, two imidazole N atoms and two carboxyl-ate O atoms from benzene-1,2,4,5-tetra-carboxyl-ate anions in a distorted square-pyramidal geometry. The benzene-1,2,4,5-tetra-carboxyl-ate anion bridges four Cu(II) ions, forming a polymeric sheet parallel to (010). In the crystal, extensive N-H⋯O and O-H⋯O hydrogen bonds link the polymeric sheets and di-methyl-formamide solvent mol-ecules into a three-dimensional supra-molecular structure.

Project description:In the title compound, [Sr(2)(C(8)H(6)O(8))(H(2)O)(4))](n), the Sr(II) ion is coordinated by six O atoms of four symmetry-related ligands and two water mol-ecules in a distorted bicapped trigonal-prismatic environment. The butane-1,2,3,4-tetra-carboxyl-ate ligands lie on inversion centers and bridge Sr(II) ions, forming a three-dimensional network. Within the three-dimensional structure, there are O-H?O hydrogen bonds involving the water mol-ecules and carboxyl-ate O 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.
