Monoclinic polymorph of poly[[di-?-aqua-triaquadi-?-oxalato-barium(II)-copper(II)] monohydrate].

ABSTRACT: A monoclinic polymorph of the title compound, {[BaCu(C(2)O(4))(2)(H(2)O)(5)]·H(2)O}(n), is reported. The structure is best described as a coordination polymer where the Cu(II) and Ba(II) centers are coordinated by five and nine O atoms, respectively, in capped quadratic antiprismatic and tetragonal pyramidal geometries. The polymerization arises due to the presence of bridging mono- and bidentate oxalate ligands as well as bridging water mol-ecules. The crystal structure is consolidated by a three-dimensional network of hydrogen bonding.

Hexa-aqua-nickel(II) bis-[tri-aqua-μ<sub>3</sub>-oxalato-di-μ-oxalato-bariumchromate(III)] tetra-hydrate.

Project description:The title compound, [Ni(H2O)6][BaCr(C2O4)3(H2O)3]2·4H2O, was obtained in the form of single crystals from the slow evaporation of an aqueous mixture of {Ba6(H2O)17[Cr(C2O4)3]4}·7H2O and NiSO4·6H2O in the molar ratio 1:4. Its structure is made up of corrugated anionic (101) layers of formula [BaCr(C2O4)3(H2O)3] n n - that leave voids accommodating the charge-compensating cations, [Ni(H2O)6]2+ (point group symmetry ), as well as the water mol-ecules of crystallization. The anionic layers are built from the connection of barium and chromium atoms through bridging oxalate ligands. The CrIII atom is hexa-coordinated by O atoms of three oxalate ligands while the BaII atom is tenfold coordinated by three O atoms of water mol-ecules and seven O atoms of four oxalate ligands. Each NiII atom sits on an inversion center and is coordinated by six water mol-ecules. One of the uncoordinated water mol-ecules is disordered over two sites, with a refined occupancy ratio of 0.51 (5):0.49 (5). In the crystal, extensive O-H⋯O hydrogen-bonding inter-actions link the anionic layers, the charge-balancing cations as well as the water mol-ecules of crystallization into a three-dimensional supra-molecular network.

Poly[tetra-aqua-di-μ(4)-malonato-barium(II)cadmium(II)].

Project description:In the title complex, [BaCd(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Ba(II) atoms, located on crystallographic twofold axes, adopt slightly distorted square-anti-prismatic coordination geometries, while the Cd(II) atoms, which lie on crystallographic centres of symmetry, have a distorted octa-hedral coordination. Each malonate dianion binds two different Cd(II) atoms and two different Ba(II) atoms. This connectivity generates alternating layers along [100] in the structure, with one type containing Cd(II) cations and malonate dianions, while the other is primarily composed of Ba(II) ions and coordinated water mol-ecules. The water mol-ecules also participate in extensive O-H⋯O hydrogen bonding.

Di-μ-azido-di-azidodi-μ-oxalato-di-histamine-tetra-copper(II) 0.9-hydrate.

Project description:The title compound, [Cu4(C2O4)2(N3)4(C5H9N3)2]·0.9H2O, contains a tetranuclear Cu(II)-based molecule composed of two oxalate-bridged Cu(II) dimers linked through end-on azide ions and related by an inversion center. The tetranuclear unit contains two crystallographically independent Cu(II) ions. One Cu(II) ion coordinates to two N atoms of a histamine mol-ecule, two O atoms of a bridging oxalate ligand, and an N atom of an end-on bridging azide ligand, leading to an elongated square-pyramidal coordination geometry in which the azide ion occupies the axial position. The other Cu(II) ion, which has a square-planar coordination geometry, is coordinated by two O atoms of a bridging oxalate ligand and two N atoms of two different azide ligands, one which is bridging. In the crystal, a two-dimensional network parallel to (010) is formed by N-H⋯N and N-H⋯O hydrogen bonds. A partially occupied solvent water mol-ecule refined to an occupancy of 0.447 (5). Two of the azide ligands were refined as disordered over two sets of sites with refined occupancies in the ratios 0.517 (8):0.483 (8) and 0.553 (5):0.447 (5).

μ-Oxalato-bis-[(2,2'-bipyridyl)-copper(II)] bis(perchlorate) dimethyl-formamide disolvate monohydrate.

Project description:The title compound, [Cu(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·2C(3)H(7)NO·H(2)O, contains doubly charged centrosymmetric dinuclear oxalato-bridged copper(II) complex cations, perchlorate anions, and DMF and water solvate mol-ecules. In the complex cation, the oxalate ligand is coordinated in a bis-bidentate bridging mode to the Cu atoms. Each Cu atom has a distorted tetra-gonal-bipyramidal environment, being coordinated by two N atoms of the two chelating bipy ligands and two O atoms of the doubly deprotonated oxalate anion. Pairs of perchlorate anions and water mol-ecules are linked into recta-ngles by O-H⋯O bonds in which the perchlorate O atoms act as acceptors and the water mol-ecules as donors. Methyl groups of the DMF solvent molecule are disordered over two sites with occupancies of 0.453 (7):0.547 (7), and the water molecule is half-occupied.

Poly[[μ-1,4-anhydro-erythritolato-di-μ-aqua-sodium(I)] monohydrate].

Project description:In the title compound, {[Na(C(4)H(7)O(3))(H(2)O)(2)]·H(2)O}(n), the sodium ion is octa-hedrally coordinated by two bridging 1,4-anhydro-erythritolate ligands, unexpectedly coordinated by the ring oxygen and four water ligands. This bonding pattern leads to one-dimensional anti-tactical polymeric chains along [010]. One of the exocyclic O atoms of the anhydro-erythritolate group is an acceptor in four hydrogen bonds, giving further evidence that it is deprotonated.

[Di-aqua-sesqui(nitrato-κO)hemi(perchlorato-κO)copper(II)]-μ-{bis-[5-methyl-3-(pyridin-2-yl)-1H-pyrazol-4-yl] selenide}-[tri-aqua-(perchlorato-κO)copper(II)] nitrate monohydrate.

Project description:In the binuclear title complex, [Cu2(ClO4)1.5(NO3)1.5(C18H16N6Se)(H2O)5]NO3·H2O, both Cu(II) ions are hexa-coordinated by O and N atoms, thus forming axially elongated CuO4N2 octa-hedra. The equatorial plane of each octa-hedron is formed by one chelating pyrazole-pyridine fragment of the organic ligand and two water mol-ecules. The axial positions in one octa-hedron are occupied by a water mol-ecule and a monodentately coordinated perchlorate anion, while those in the other are occupied by a nitrate anion and a disordered perchlorate/nitrate anion with equal site occupancy. The pyrazole-pyridine units of the organic selenide are trans-oriented to each other with a C-Se-C angle of 96.01 (14)°. In the crystal, uncoordinated nitrate anions and the coordinating water mol-ecules are involved in O-H⋯O and N-H⋯O hydrogen bonds, forming a bridge between the pyrazole group and the coordinating water mol-ecules. Further O-H⋯O hydrogen bonds between the complex mol-ecules and a π-π stacking inter-action with a centroid-centroid distance of 3.834 (4) Å are also observed.

Poly[μ-aqua-di-μ-benzoato-lead(II)].

Project description:The reaction of lead(II) nitrate and benzoic acid in aqueous solution yields the title polymer, [Pb(C(7)H(5)O(2))(2)(H(2)O)](n). The asymmetric unit contains one Pb(II) ion, two benzoate ligands and one water mol-ecule. The Pb-O bond distances are in the range 2.494 (4)-2.735 (4) Å. The Pb⋯Pb distance is 4.0683 (4) Å, indicating an insignificant metal-metal inter-action. The Pb(II) atom has a distorted penta-gonal-bipyramidal geometry chelated by two carboxyl-ate O atoms. The Pb atoms are bridged through a coordinating water mol-ecule and two carboxyl-ate O atoms from another two benzoate ligands, giving an infinite three-dimensional supra-molecular structure. O-H⋯O hydrogen-bonding inter-actions involved the coordinating water and carboxyl-ate O atoms enhance the stability of the supra-molecular arrangement.

catena-Poly[[(1,10-phenanthroline)copper(II)]-μ-oxalato].

Project description:In the title coordination polymer, [Cu(C(2)O(4))(C(12)H(8)N(2))](n), the Cu(II) atom is six-coordinated by four O atoms from two oxalate ligands and two N atoms from one 1,10-phenanthroline (phen) ligand in a distorted octa-hedral coordination geometry. The oxalate anions act as bis-bidentate ligands, bridging the Cu-phen units in zigzag chains extending parallel to [100]. Inter-chain C-H⋯O hydrogen bonding and π-π stacking inter-actions [centroid-centroid distance = 3.7439 (17) Å] assemble neighboring chains, forming a three-dimensional supra-molecular network.

Di-μ-glutarato-κO:O-bis-[aqua-(1,10-phenanthroline-κN,N')copper(II)].

Project description:In the centrosymmetric dinuclear title complex, [Cu(2)(C(5)H(6)O(4))(2)(C(12)H(18)N(2))(2)(H(2)O)(2)], the Cu(II) atom displays a dis-torted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water mol-ecule is located at the apical position. Of the two water H atoms, one is engaged in an intra-molecular hydrogen bond with a free oxygen of the dianion whereas the second is engaged in an inter-molecular hydrogen bond, building a corrugated layer parallel to (100). These layers are further connected through π-π stacking inter-actions involving symmetry-related phenanthroline rings [centroid-centroid distance = 3.5599 (17) and 3.5617 (18) Å], building a three dimensionnal network. C-H⋯π inter-actions involving the phenanthroline ring system are also observed.

Poly[tri-μ-aqua-di-aqua-μ-phosphono-formato-cobalt(II)sodium].

Project description:The title complex, [CoNa(CO5P)(H2O)5]n, was obtained by reacting sodium phosphono-formate with cobalt nitrate. The complex contains cobalt(II) and sodium ions, which are bridged by the O atoms of two aqua ligands. The Co(II) ion is octahedrally coordinated by three phosphonoformato ligands (one bi- and the other monodentate) and by two O atoms from the bridging aqua ligands. The sodium cation is hexa-coordinated by six O atoms from four bridging and two terminal aqua ligands. The complex mol-ecules are linked to give a three-dimensional structure by phosphono-formate ligands bridging Co(II) atoms and water mol-ecules establishing cobalt-sodium bridges. O-H⋯O hydrogen bonding between the aqua ligands and all O atoms of the phosphono-formato ligand and neighbouring aqua ligands help to consolidate the packing.
