Poly[di-?(4)-benzene-1,4-dicarboxyl-ato-?(6)-succinato-diholmium(III)].

ABSTRACT: The title compound, [Ho(2)(C(4)H(4)O(4))(C(8)H(4)O(4))(2)](n), was synthesized hydro-thermally. The Ho atom is coordinated by four O atoms from four benzene-1,4-dicarboxyl-ate (BDC) anions and four O atoms from three succinate anions, in a distorted square-anti-prismatic coordination geometry. The anti-prisms are bridged by the benzene-1,4-dicarboxyl-ate and succinate anions, into a three-dimensional coordination network. The succinate anions are located on centres of inversion.

Poly[[dodeca-aqua-(?(4)-benzene-1,4-dicarboxyl-ato)(?(2)-4,4'-bipyridine-?(2)N:N')dicerium(III)] bis-(benzene-1,4-dicarboxyl-ate)].

Project description:The asymmetric unit of the title compound, {[Ce(2)(C(8)H(4)O(4))(C(10)H(8)N(2))(H(2)O)(12)](C(8)H(4)O(4))(2)}(n), consists of half a Ce(III) cation, a quarter of a coordinated benzene-1,4-dicarboxyl-ate (bdc(2-)) dianion, a quarter of a 4,4'-bipyridine (bpy) mol-ecule, three water mol-ecules and a half of an uncoordinated benzene-1,4-dicarboxyl-ate dianion. The Ce(III) ion is located on a twofold rotation axis and exhibits a distorted trigonal prism square-face tricapped coordination geometry. The coordinated and uncoordinated bdc(2-) ions and the bpy mol-ecule lie about special positions of site symmetries 2/m, m and 2/m, respectively. The Ce(III) ions are bridged by the bdc(2-) and bpy ligands, giving a sheet structure parallel to the ac plane. The uncoordinated bdc(2-) dianion exists between the sheets and links the sheets by inter-molecular O-H?O hydrogen bonds between the uncoordinated bdc(2-) and coordinated water mol-ecules. A ?-? stacking inter-action between the uncoordinated bdc(2-) dianion and the bpy ligand [centroid-centroid distance = 3.750?(4)?Å] is also observed.

Poly[diaqua-penta-kis(?(4)-benzene-1,2-dicarboxyl-ato)(?(3)-benzene-1,2-dicarboxyl-ato)tetra-thulium(III)].

Project description:The title compound, [Tm(4)(C(8)H(4)O(4))(6)(H(2)O)(2)](n), has been synthesized hydro-thermally. The asymmetric unit has four unique Tm(III) ions that are six-, seven-, eight- and nine-coordinate. The cations are inter-connected by bridging benzene-1,2-dicarboxyl-ate (BDC) anions to form an infinite two-dimensional framework, in which the BDC ligands adopt three different coordination modes. Adjacent sheets are further packed to form a three-dimensional supra-molecular framework through O-H?O hydrogen bonds.

Poly[tris-(?-2-amino-benzene-1,4-dicarboxyl-ato)tetra-kis-(N,N-dimethyl-formamide)-diyttrium(III)].

Project description:The asymmetric unit of the title coordination polymer, [Y(2)(C(8)H(5)NO(4))(3)(C(3)H(7)NO)(4)](n), contains one Y(3+) ion, three half-mol-ecules of the 2-amino-benzene-1,4-dicarboxyl-ate (abz) dianion and two O-bonded N,N-dimethyl-formamide (DMF) mol-ecules. Each abz half-mol-ecule is completed by crystallographic inversion symmetry and its -NH(2) group is disordered in each case [relative occupancies within the asymmetric unit = 0.462?(18):0.538?(18), 0.93?(2):0.07?(2) and 0.828?(16):0.172?(16)]. The combination of disorder and crystal symmetry means that each of the four C-H atoms of the benzene ring of each of the dianions bears a statistical fraction of an -NH(2) group. The coordination geometry of the yttrium ion is a fairly regular YO(8) square anti-prism arising from its coordination by two DMF mol-ecules, four monodentate abz dianions and one O,O-bidentate abz dianion. The polymeric building unit is a dimeric paddle-wheel with two metal ions linked by four bridging abz dianions. Further bridging linkages connect the dimers into a three-dimensional framework containing voids in which highly disordered DMF mol-ecules are presumed to reside.

Poly[piperazinediium [[aqua-bismuth-ate(III)]-di-?-pyridine-2,6-dicarboxyl-ato-bis-muthate(III)-di-?-pyridine-2,6-dicarboxyl-ato] monohydrate].

Project description:The title compound, {(C(4)H(12)N(2))[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)]·H(2)O}(n) or {(pipzH(2))[Bi(2)(pydc)(4)(H(2)O)]·H(2)O}(n), where pydcH(2) is pyridine-2,6-dicarboxylic acid and pipz is piperazine, was obtained by reaction of Bi(NO(3))(3)·5H(2)O with (pipzH(2))(pydc-H)(2)·3H(2)O in a 1:2 molar ratio in aqueous solution. There are two independent Bi(III) atoms in the structure, one of which is eight-coordinate with a distorted bicapped trigonal-prismatic geometry, and another which is nine-coordinate with a distorted tricapped trigonal-prismatic geometry. The carboxyl-ate groups of the (pydc)(2-) ligands link dinuclear [Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)](2-) units into one-dimensional coordin-ation polymers. The pipzH(2) (2+) cations (site symmetry ) and non-coordinated water mol-ecules lie between these polymers, forming N-H?O and O-H?O hydrogen bonds to the O atoms of the carboxylate groups.

catena-Poly[[[aqua-(1,10-phenan-throline)cadmium(II)]-?-benzene-1,4-dicarboxyl-ato] benzene-1,4-dicarboxylic acid hemisolvate].

Project description:A new cadmium(II) coordination polymer, {[Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5C(8)H(6)O(4)}(n), has been synthesized under hydro-thermal conditions. The asymmetric unit contains one Cd(II) atom, one benzene-1,4-dicarboxyl-ate anion, one 1,10-phenanthroline ligand, one coordinated water mol-ecule and half of an uncoordinated benzene-1,4-dicaboxylic acid solvent mol-ecule. The Cd(II) atom is in the centre of a monocapped distorted octa-hedron made up of four O atoms of two chelating benzene-1,4-dicarboxyl-ate anions, one water O atom and two 1,10-phenanthroline N atoms. The metal centres are connected via bis-chelating benzene-1,4-dicarboxyl-ate anions into a zigzag chain structure along [001]. These chains are further connected by O-H?O hydrogen bonds between the water mol-ecules and adjacent carboxyl-ate O atoms. Additional O-H?O hydrogen bonding between the uncoordinated benzene-1,4-dicaboxylic acid mol-ecules along [010] consolidates the structure.

Poly[tris-(2,5-dimethyl-benzene-1,4--dicarboxyl-ato)bis-(pyridine)trizinc(II)].

Project description:The asymmetric unit of the title polymeric compound, [Zn(3)(C(10)H(8)O(4))(3)(C(5)H(5)N)(2)](n) or [Zn(3)(dmbdc)(3)(py)(2)](n) (dmbdc = 2,5-dimethyl-benzene-dicarboxyl-ate; py = pyridine) contains two Zn(II) ions, one of which is located on an inversion centre, one and a half 2,5-dimethyl-benzene-dicarboxyl-ate ligands and one pyridine ligand. Each ZnO(6) octa-hedron is sandwiched between two ZnO(4)N square-pyramids, forming a trinuclear zinc secondary building unit (SBU); each SBU is further linked by six 2,5-dimethyl-benzene-dicarboxyl-ate ligands with six adjacent trinuclear zinc SBU's, forming a two-dimensional layer structure with a (3,6) net. One of the three zinc ions is octa-hedrally coordinated and the other two are square-pyramidally coordinated. The coordination modes for 2,5-dimethyl-benzene-dicarboxyl-ates are bis-(bidentate) or bidentate-tridentate.

Poly[[aqua-tris-(?-benzene-1,4-dicarboxyl-ato)tricobalt(II)] methanol monosolvate monohydrate].

Project description:The asymmetric unit of the title compound, {[Co(3)(C(8)H(4)O(4))(3)(H(2)O)]·CH(3)OH·H(2)O}(n), consists of four crystallographically independent Co cations, four benzene-1,4-dicarboxyl-ate (bdc) anions, two water and one methanol solvent mol-ecule. Two of the Co cations and two of the bdc anions are located on centres of inversion, whereas all other atoms are located in general positions. In the crystal, two Co atoms are only fourfold coordinated by three O atoms from three bdc ligands and by one O atom from one coordinated water mol-ecule, while a third Co atom is coordinated by four O atoms from four bdc ligands within a strongly distorted tetra-hedral geometry. The other two Co cations are octa-hedrally coordinated by six O atoms from six bdc anions. The Co cations are linked by the bdc anions into a three-dimensional framework. From this arrangement, cavities are formed in which additional methanol and water mol-ecules are embedded.

Project description:The asymmetric unit of the title coordination polymer, {[La(2)(C(8)H(4)O(4))(3)(H(2)O)]·0.5H(2)O}(n), contains two independent La(III) atoms, one of which is surrounded by eight carboxyl-ate-O atoms from six benzene-1,2-dicarboxyl-ate (BDC) anions in a bicapped trigonal-prismatic geometry. The other La(III) atom is nine-coordinated in a tricapped trigonal-prismatic geometry, formed by eight carboxyl-ate-O atoms from six BDC anions and a coordinated water mol-ecule. The BDC anions bridge the La(III) atoms, forming a two-dimensional polymeric complex parallel to (001). The crystal structure contains weak O-H?O and non-classical C-H?O hydrogen bonds. A C-H?? inter-action is also present in the crystal structure. The uncoordinated water molecule shows half-occupation.

Project description:The asymmetric unit of the title complex, [Sr(5)(C(8)H(4)O(4))(4)(HCO(2))(2)](n), contains three independent Sr(II) ions, one of which is located on an inversion center.
