N,N'-Di-hydroxy-benzene-1,2:4,5-tetra-carboximide dihydrate.

ABSTRACT: In the title compound, C10H4N2O6·2H2O, the organic mol-ecule has crystallographically imposed inversion symmetry. The atoms of the three fused rings of the mol-ecule are coplanar within 0.0246?(8)?Å, while the two hy-droxy O atoms are displaced from the mean plane of the mol-ecule by 0.127?(1)?Å. In the crystal, infinite near-planar layers of close-packed mol-ecules are formed by hydrogen bonding between water O-H donor groups and carbonyl O-atom acceptors, and by weak inter-actions between C-H donor groups and water O-atom acceptors. The layers are parallel to the {102} family of planes. The stacked planes are held together by hydrogen bonding between N-OH donor groups and water O-atom acceptors.

In the title compound, C10H4N2O6·2H2O, the organic mol-ecule has crystallographically imposed inversion symmetry. The atoms of the three fused rings of the mol-ecule are coplanar within 0.0246 (8) Å, while the two hy-droxy O atoms are displaced from the mean plane of the mol-ecule by 0.127 (1) Å. In the crystal, infinite near-planar layers of close-packed mol-ecules are formed by hydrogen bonding between water O-H donor groups and carbonyl O-atom acceptors, and by weak inter-actions between C-H ...[more]

1,2-Bis(1H-tetra-zol-5-yl)benzene dihydrate.

Project description:The asymmetric unit of the title compound, C(8)H(6)N(8)·2H(2)O, contains one half-mol-ecule, with the benzene ring on a centre of symmetry, and two uncoordinated water mol-ecules. The benzene ring is oriented at a dihedral angle of 34.43?(12)° with respect to the tetra-zole ring. Strong O-H?N hydrogen bonds link the water mol-ecules to the N atoms of the tetra-zole ring. In the crystal structure, strong inter-molecular O-H?O and O-H?N hydrogen bonds link the mol-ecules into a network. One of the water H atoms is disordered over two positions and was refined with occupancies of 0.50.

Crystal structure of tetra-ethyl-ammonium chloride 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene.

Project description:Equimolar qu-anti-ties of tetra-ethyl-ammonium chloride (Et4NCl) and 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene (o-DITFB or o-C6F4I2) have been co-crystallized in a solution of di-chloro-methane yielding a pure halogen-bonded compound, 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene-tetra-ethyl ammonium chloride (2/1), Et4N(+)·Cl(-)·2C6F4I2, in the form of translucent needles. [(Et4NCl)(o-C6F4I2)2] packs in the C2/c space group. The asymmetric unit includes one mol-ecule of DITFB, one Et4N(+) cation located on a twofold rotation axis, and one chloride anion also located on a twofold rotation symmetry axis. This compound has an inter-esting halogen-bonding environment surrounding the halide. Here, the chloride anion acts as a tetra-dentate halogen bond acceptor and forms a distorted square-pyramidal geometry, with I?Cl(-)?I angles of 80.891?(6) and 78.811?(11)°, where two crystallographically distinct iodine atoms form halogen bonds with the chloride anion. Resulting from that square-pyramidal geometry are short contacts between some of the adjacent F atoms. Along the b axis, the halogen-bonding inter-action results in a polymeric network, producing a sheet in which the two closest chloride ions are 7.8931?(6)?Å apart. The Et4N(+) cation alternates in columns with the halide ion. The expected short contacts (shorter than the sum of their van der Waals radii) are observed for the halogen bonds [3.2191?(2) and 3.2968?(2)?Å], as well as almost linear angles [170.953?(6) and 173.529?(6)°].

Crystal structures of sodium-, lithium-, and ammonium 4,5-di-hydroxy-benzene-1,3-di-sulfonate (tiron) hydrates.

Project description:The solid-state structures of the Na+, Li+, and NH4+ salts of the 4,5-di-hydroxy-benzene-1,3-di-sulfonate (tiron) dianion are reported, namely disodium 4,5-di-hydroxy-benzene-1,3-di-sulfonate, 2Na+·C6H4O8S22-, μ-4,5-di-hydroxy-benzene-1,3-di-sulfonato-bis-[aqua-lithium(I)] hemihydrate, [Li2(C6H4O8S2)(H2O)2]·0.5H2O, and di-ammonium 4,5-di-hydroxy-benzene-1,3-di-sulfonate monohydrate, 2NH4+·C6H4O8S22-·H2O. Inter-molecular inter-actions vary with the size of the cation, and the asymmetric unit cell, and the macromolecular features are also affected. The sodium in Na2(tiron) is coordinated in a distorted octa-hedral environment through the sulfonate oxygen and hydroxyl oxygen donors on tiron, as well as an inter-stitial water mol-ecule. Lithium, with its smaller ionic radius, is coordinated in a distorted tetra-hedral environment by sulfonic and phenolic O atoms, as well as water in Li2(tiron). The surrounding tiron anions coordinating to sodium or lithium in Na2(tiron) and Li2(tiron), respectively, result in a three-dimensional network held together by the coordinate bonds to the alkali metal cations. The formation of such a three-dimensional network for tiron salts is relatively rare and has not been observed with monovalent cations. Finally, (NH4)2(tiron) exhibits extensive hydrogen-bonding arrays between NH4+ and the surrounding tiron anions and inter-stitial water mol-ecules. This series of structures may be valuable for understanding charge transfer in a putative solid-state fuel cell utilizing tiron.

1,2-Diiodo-4,5-dimethyl-benzene.

Project description:The structure of the title compound, C(8)H(8)I(2), conforms closely to the mm2 symmetry expected for the free mol-ecule and is the first reported structure of a diiodo-dimethyl-benzene. Repulsion by neighboring I atoms and the neighboring methyl groups opposite to them results in a slight elongation of the mol-ecule along the approximate twofold rotation axis that bis-ects the ring between the two I atoms. In the extended structure, the mol-ecules form inversion-related pairs which are organized in approximately hexa-gonal close-packed layers and the layers then stacked so that mol-ecules in neighboring layers abut head-to-tail in a manner that optimizes dipole-dipole inter-actions.

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. In the crystal, the Sr(II) ions (coordination numbers 8, 9 and 12) are connected by two crystallographically distinct benzene-1,2-dicarboxyl-ate ligands and one formate ligand, forming a two-dimensional polymer parallel to (001).

Crystal structure of tetra-butyl-ammonium bromide-1,2-di-iodo-3,4,5,6-tetra-fluoro-benzene-di-chloro-methane (2/2/1).

Project description:The crystallization of a 1:1 molar solution of 1,2-di-iodo-3,4,5,6-tetra-fluoro-benzene (o-DITFB) and tetra-butyl-ammonium bromide (n-Bu4NBr) from di-chloro-methane yielded pure white crystals of a halogen-bonded compound, C16H36N(+)·Br(-)·C6F4I2·0.5CH2Cl2 or [(n-Bu4NBr)(o-DITFB)]·0.5CH2Cl2. The compound may be described as a quaternary system and may be classified as a salt-cocrystal solvate. The asymmetric unit contains one mol-ecule of solvent, two o-DITFB mol-ecules, two cations (n-Bu4N(+)) and two crystallographically distinct bromide ions [?I ? Br- ? I = 144.18?(1) and 135.35?(1)°]. The bromide ion is a bidentate halogen-bond acceptor which inter-acts with two covalently bonded iodines (i.e. halogen-bond donors), resulting in a one-dimensional polymeric zigzag chain network approximately along the a axis. The observed short contacts and angles are characteristic of the non-covalent inter-action [d C-I?Br = 3.1593?(4)-3.2590?(5)?Å; ?C-I?Br = 174.89?(7) and 178.16?(7)°]. It is noted that iodine acts as both a halogen-bond donor and a weak CH hydrogen-bond acceptor, while the bromide ions act as acceptors for weak CH hydrogen bonds and halogen bonds.
