Poly[?(2)-aqua-diaqua-(?(8)-3-nitro-benzene-1,2-dicarboxylato)(?(6)-3-nitro-benzene-1,2-dicarboxylato)tetra-sodium].

ABSTRACT: In the title layered coordination polymer, [Na(4)(C(8)H(3)NO(6))(2)(H(2)O)(3)](n), the doubly deprotonated 3-nitro-benzene-1,2-dicarboxyl-ate ligands exhibit ?(8)- and ?(6)-coordination modes to the sodium ions, generating sheets lying parallel to (001). The coordination environments of the sodium ions are distorted octa-hedral, distorted trigonal-bipyramidal and moncapped trigonal-prismatic. One of the nitro groups is disordered over two sets of sites with site-occupancy factors 0.580?(8):0.419?(2). A network of O-H?O and O-H?N hydrogen bonds helps to establish the packing.

The Ni and Na atoms are linked by water bridges, forming infinite chains, which are connected by strong O-H?O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules into a three-dimensional network.

Poly[tetra-μ-aqua-diaqua-tetra-kis-[μ-(E)-2-nitro-cinnamato]tetra-rubidium].

Project description:In the structure of the title compound, [Rb(4)(C(9)H(6)NO(4))(4)(H(2)O)(6)](n), the asymmetric unit comprises four rubidium cations, two of which have an RbO(7) coordination polyhedron with a monocapped distorted octa-hedral stereochemistry and two of which have a distorted RbO(6) octa-hedral coordination. The bonding about both the seven-coordinate cations is similar, comprising one monodentate water mol-ecule together with three bridging water mol-ecules and three carboxyl-ate O-atom donors, two of which are bridging. The environments around the six-coordinate cations are also similar, comprising a monodentate nitro O-atom donor, a bridging water mol-ecule and four bridging carboxyl-ate O-atom donors [overall Rb-O range = 2.849 (2)-3.190 (2) Å]. The coordination leads to a two-dimensional polymeric structure extending parallel to (001), which is stabilized by inter-layer water O-H⋯O hydrogen-bonding associations to water, carboxyl and nitro O-atom acceptors, together with weak inter-ring π-π inter-actions [minimum ring centroid-centroid separation = 3.5319 (19) Å].

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[[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.

Project description:In the title compound, {[Fe(II)(C(8)H(4)N(2))(2)(H(2)O)(2)][Fe(III)Cl(4)](2)·4CH(3)NO(2)}(n), the Fe(II) and Fe(III) ions are hexa- and tetra-coordinated, respectively.

Poly[[μ(2)-aqua-tetraaquahexakis(μ(4)-naph-thalene-2,6-dicarboxylato)tetra-holmium(III)] 1.75-hydrate].

Project description:In the title compound, {[Ho(4)(C(12)H(6)O(4))(6)(H(2)O)(5)]·1.75H(2)O}(n), which is isostructural with its Tb(3+)- and Eu(3+)-containing analogues, there are four crystallographically independent Ho(3+) centres, each exhibiting a highly distorted HoO(8) bicapped trigonal-prismatic coordination environment. Adjacent polyhedra are inter-connected via the carboxyl-ate groups and one μ(2)-bridging water mol-ecule, forming one-dimensional chains propagating along [100]. The naphthalene-2,6-dicarboxylate ligands further inter-connect these chains into a three-dimensional framework, which has zigzag channels housing the water mol-ecules. Two naphthalene-2,6-dicarboxylate bridging ligands have their centroids located on crystallographic centres of inversion. One water O atom has a fixed site occupancy factor of 0.75.
