Monoclinic polymorph of poly[aqua(?(4)-hydrogen tartrato)sodium].

ABSTRACT: A monoclinic polymorph of the title compound, [Na(C(4)H(5)O(6))(H(2)O)](n), is reported and complements an ortho-rhom-bic form [Kubozono, Hirano, Nagasawa, Maeda & Kashino (1993 ?). Bull. Chem. Soc. Jpn, 66, 2166-2173]. The asymmetric unit contains a hydrogen tartrate anion, an Na(+) cation and a water mol-ecule. The Na(+) ion is surrounded by seven O atoms derived from one independent and three symmetry-related hydrogen tartrate anions, and a water mol-ecule, forming a distorted penta-gonal-bipyramidal geometry. Independent units are linked via a pair of inter-molecular bifurcated O-H?O acceptor bonds, generating an R(2) (1)(6) ring motif to form polymeric two-dimensional arrays parallel to the (100) plane. In the crystal packing, the arrays are linked by adjacent ring motifs, together with additional inter-molecular O-H?O inter-actions, into a three-dimensional network.

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

Project description: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.

A monoclinic polymorph of sodium birnessite for ultrafast and ultrastable sodium ion storage.

Project description:Sodium transition metal oxides with layered structures are attractive cathode materials for sodium-ion batteries due to their large theoretical specific capacities. However, these layered oxides suffer from poor cyclability and low rate performance because of structural instability and sluggish electrode kinetics. In the present work, we show the sodiation reaction of Mn3O4 to yield crystal water free NaMnO2-y-?(OH)2y, a monoclinic polymorph of sodium birnessite bearing Na/Mn(OH)8 hexahedra and Na/MnO6 octahedra. With the new polymorph, NaMnO2-y-?(OH)2y exhibits an enlarged interlayer distance of about 7?Å, which is in favor of fast sodium ion migration and good structural stability. In combination of the favorable nanosheet morphology, NaMn2-y-?(OH)2y cathode delivers large specific capacity up to 211.9?mAh?g-1, excellent cycle performance (94.6% capacity retention after 1000 cycles), and outstanding rate capability (156.0?mAh?g-1 at 50?C). This study demonstrates an effective approach in tailoring the structural and electrochemical properties of birnessite towards superior cathode performance in sodium-ion batteries.

A second monoclinic polymorph of ethyl-enediammonium bis-(hydrogen squarate) monohydrate.

Project description:The title compound, C(2)H(10)N(2) (2+)·2HC(4)O(4) (-)·H(2)O, a new polymorph of ethyl-enediammonium bis-(hydrogen squarate) monohydrate, was synthesized by slow evaporation of an acid solution. The asymetric unit contains two hydrogen squarate anions, two half-mol-ecules of protonated ethyl-enediamine arranged around a twofold axis and one water mol-ecule. In the crystal, N-H?O and O-H?O hydrogen bonds between the hydrogen squarate anions, protonated N atoms from the amine group and water mol-ecules lead to a three-dimensional framework. In particular, the cohesion between the squarate groups is ensured by very short intermolecular hydrogen bonds bonds. The title compound crystallized together with the previously reported polymorph [Mathew et al. (2002 ?). J. Mol. Struct.641, 263-279].

2-Pyridone: monoclinic polymorph.

Project description:The asymmetric unit in the title compound, C(5)H(5)NO, comprises two independent but virtually identical mol-ecules of 2-pyridone, and represents a monoclinic polymorph of the previously reported ortho-rhom-bic (P2(1)2(1)2(1)) form [Penfold (1953 ?). Acta Cryst.6, 591-600; Ohms et al. (1984 ?). Z. Kristallogr.169, 185-200; Yang & Craven (1998 ?). Acta Cryst. B54, 912-920]. The independent mol-ecules are linked into supra-molecular dimers via eight-membered {?HNC(O)}(2) amide synthons in contrast to the helical supra-molecular chains, mediated by {?HNC(O)} links, found in the ortho-rhom-bic form.

A monoclinic polymorph of theophylline.

Project description:A monoclinic polymorph of theophylline, C(7)H(8)N(4)O(2), has been obtained from a chloro-form/methanol mixture by evaporation under ambient conditions. The new polymorph crystallizes with two mol-ecules in the asymmetric unit. The structure features inter-molecular N-H⋯O hydrogen bonds, resulting in the formation of dimers between two crystallographically different mol-ecules; each mol-ecule acts as both donor and acceptor.

catena-Poly[[aqua-(ethyl anilinophospho-nato-?O)sodium(I)]-di-?-aqua].

Project description:In the title compound, [Na(C(8)H(11)NO(3)P)(H(2)O)(3)](n), the sodium cation is octa-hedrally coordinated by five water mol-ecules and one O-bonded ethyl anilinophospho-nate anion. Four of the water mol-ecules bridge to adjacent sodium ions, resulting in an infinite chain of edge-sharing NaO(6) polyhedra. A network of N-H?O and O-H?O hydrogen bonds helps to stabilize the crystal structure.

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.

Dicyclo-hexyl-ammonium thio-cyanate: monoclinic polymorph.

Project description:The title salt, C(12)H(24)N(+)·NCS(-), represents a monoclinic polymorph of the previously reported ortho-rhom-bic form [Khawar Rauf et al. (2008 ?). Acta Cryst. E64, o366]. Two independent formula units comprise the asymmetric unit with the major difference in their mol-ecular structures relating to the relative dispositions of the cyclo-hexyl rings [dihedral angles = 79.88?(6) and 67.72?(5)°]. Further, the independent anions form distinctive patterns of hydrogen-bonding inter-actions, i.e. 2 × N-H?N versus N-H?N and N-H?S. The resulting supra-molecular architecture is a supra-molecular chain along the c axis based on a square-wave topology.

Project description:The asymmetric unit of the title compound, [Na(C(13)H(9)BrNO(4)S)(H(2)O)(0.5)](n), contains two Na(+) cations, two substituted benzoate anions and one water molecule of crystallization. The Na(+) cations are coordinated in an octa-hedral geometry by two carboxyl-ate O atoms, two sulfonyl O atoms and two water O atoms. The latter two ligands occupy trans positions. The polymeric network structure of the title complex is characterized by a layered assembly parallel to (001) and is further consolidated by N-H?O, O-H?O and C-H?O hydrogen-bonding inter-actions.

Poly[?(2)-aqua-(?(3)-2,5-dichloro-benzene-sulfonato)sodium].

Project description:In the title compound, [Na(C(6)H(3)Cl(2)O(3)S)(H(2)O)](n), the Na(I) ion is penta-coordinated by three dichloro-benzene-sulfonate anions and two water mol-ecules, forming a distorted trigonal-bipyramidal geometry. The Na(I) ions are bridged by the sulfonate groups and the water mol-ecules, leading to a polymeric layer structure parallel to the bc plane in which O-H?O hydrogen bonds are observed.
