Crystal structure of rubidium methyl-diazo-tate.

ABSTRACT: The title compound, Rb⁺·H₃CN₂O^-, has been crystallized in liquid ammonia as a reaction product of the reductive ammonolysis of the natural compound streptozocin. Elemental rubidium was used as reduction agent as it is soluble in liquid ammonia, forming a blue solution. Reductive bond cleavage in biogenic materials under kinetically controlled conditions offers a new approach to gain access to sustainably produced raw materials. The anion is nearly planar [dihedral angle O-N-N-C = -0.4?(2)°]. The Rb⁺ cation has a coordination number of seven, and coordinates to five anions. One anion is bound via both its N atoms, one by both O and N, two anions are bound by only their O atoms, and the last is bound via the N atom adjacent to the methyl group. The diazo-tate anions are bridged by cations and do not exhibit any direct contacts with each other. The cations form corrugated layers that propagate in the (-101) plane.

Crystal structure of rubidium peroxide ammonia disolvate.

Project description:The title compound, Rb2O2·2NH3, has been obtained as a reaction product of rubidium metal dissolved in liquid ammonia and glucuronic acid. As a result of the low-temperature crystallization, a disolvate was formed. To our knowledge, only one other solvate of an alkali metal peroxide is known: Na2O2·8H2O has been reported by Grehl et al. [Acta Cryst. (1995), C51, 1038-1040]. We determined the peroxide bond length to be 1.530?(11)?Å, which is in accordance with the length reported by Bremm & Jansen [Z. Anorg. Allg. Chem. (1992), 610, 64-66]. One of the ammonia solvate molecules is disordered relative to a mirror plane, with 0.5 occupancy for the corresponding nitrogen atom.

Crystal structure of 2-diazo-imidazole-4,5-dicarbo-nitrile.

Project description:In the title compound, C5N6, all the atoms are approximately coplanar. In the crystal, mol-ecules are packed with short contact distances of 2.885 (2) (between the diazo N atom connected to the ring and a cyano N atom on a neighboring mol-ecule) and 3.012 (2) Å (between the terminal diazo N atom and an N atom of a neighboring imidazole ring).

Crystal structure of 2-(methyl-amino)-tropone.

Project description:The title compound, 2-(methyl-amino)-cyclo-hepta-2,4,6-trien-1-one, C8H9NO, crystallizes in the monoclinic space group P21/c, with three independent mol-ecules in the asymmetric unit. The planarity of the mol-ecules is indicated by planes fitted through the seven ring carbon atoms. Small deviations from the planes, with an extremal r.m.s. deviation of 0.0345 Å, are present. In complexes of transition metals with similar ligands, the large planar seven-membered aromatic rings have shown to improve the stability of the complex. Two types of hydrogen-bonding inter-actions, C-H⋯O and N-H⋯O, are observed, as well as bifurcation of these inter-actions. The N-H⋯O inter-actions link mol-ecules to form infinite chains. The packing of mol-ecules in the unit cell shows a pattern of overlapping aromatic rings, forming column-like formations. π-π inter-actions are observed between the overlapping aromatic rings at 3.4462 (19) Å from each other.

Crystal structure of 3-methyl-5-tri-methyl-silyl-1H-pyrazole.

Project description:The title compound, C7H14N2Si, crystallizes in a tetra-gonal space group and exists as an N-H?N hydrogen-bonded tetra-mer, formed around the crystallographic fourfold rotoinversion axis. The mol-ecular identity is clearly the 5-tri-methyl-silyl-3-methyl-1H-pyrazole tautomer and the structure is isomorphous with that of 5-tert-butyl-3-methyl-1H-pyrazole [Foces-Foces & Trofimenko (2001 ?). Acta Cryst. E57, o32-o34].

Crystal structure of p-toluene-sulfonyl-methyl isocyanide.

Project description:The mol-ecule of the commercially available title compound, C9H9NO2S, has crystallographically imposed mirror symmetry, the mirror plane passing through the isocyanide group and the para-C atoms, the methyl C atom and the S atom of the methyl 4-tolyl sulfone moiety. In the crystal, C-H?O hydrogen-bond inter-actions link the mol-ecules into chains running parallel to the b axis.

Crystal structure of 2,4,6-tri-methyl-benzoic anhydride.

Project description:The title compound, C20H22O3, was formed in the reaction between 2,4,6-tri-methyl-benzoic acid and N,N-diiso-propyl-ethyl-amine in the presence of 1,3-di-chloro-1,3-bis-(di-methyl-amino)-propenium hydrogen dichloride, and was recrystallized from diethyl ether solution. It is the first exclusively alkyl-substituted benzoic anhydride to have been structurally characterized. The asymmetric unit consists of a half mol-ecule, the other half of which is generated by twofold rotation symmetry; the dihedral angle between the symmetry-related aromatic rings is 54.97?(3)°. The geometric parameters of the aromatic ring are typical of those for 2,4,6-tri-methyl-phenyl substituted groups. The C=O and C-O bond lengths are 1.1934?(12) and 1.3958?(11)?Å, respectively, and the angle between these three atoms (O=C-O) is 121.24?(9)°. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds and C-H?? inter-actions. The packing features wavy chains that extend parallel to [001].

Crystal structure of methyl N-ferro-cenyl-carbamate.

Project description:The asymmetric unit of the title compound, [Fe(C5H5)(C7H8NO2)], contains two independent mol-ecules consisting of a ferrocenyl moiety and a nitro-gen-bound methyl carbamate. These units are almost perpendicular to each other, making dihedral angles of 87.74?(9) and 87.32?(8)°. In each independent mol-ecule, the cyclo-penta-dienyl rings deviate slightly from an eclipsed conformation and lie virtually parallel [dihedral angles = 1.42?(15) and 0.49?(13)°]. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds into chains along the a-axis direction.

Crystal structure of methyl 1,3-benzoxazole-2-carboxylate

Project description:The herringbone structure of methyl 1,3-benzoxazole-2-carboxylate is characterized by strong C—H⋯N and weak C—H⋯O hydrogen bonds, and further stabilized by C—O⋯π and π–π interactions. The title compound, C9H7NO3, crystallizes in the monoclinic (P21) space group. In the crystal, the almost planar molecules display a flattened herringbone arrangement. Stacking molecules are slipped in the lengthwise and widthwise directions and are linked by π–π interactions [d(Cg⋯Cg = 3.6640 (11) Å]. The structure is characterized by strong C—H⋯N and weak C—H⋯O hydrogen bonds, and further stabilized by C–O⋯π interactions.

Crystal structure of 2,5-di-methyl-anilinium salicylate.

Project description:The title mol-ecular salt, C8H12N(+)·C7H5O3 (-) arose from the proton-transfer reaction between 2,5-xylidine and salicylic acid. In the anion, the dihedral angle between the planes of the aromatic ring and the -CO2 (-) group is 11.08 (8)°; this near planarity is consolidated by an intra-molecular O-H⋯O hydrogen bond. In the crystal, the components are connected by N-H⋯O hydrogen bonds, with all three O atoms in the anion acting as acceptors; the result is a [100] chain. The structure also features weak C-H⋯O bonds and aromatic π-π stacking [centroid-to-centroid distance = 3.7416 (10) Å] inter-actions, which lead to a three-dimensional network.

Crystal structure of 4-methyl-N-(4-methyl-benz-yl)benzene-sulfonamide.

Project description:The title compound, C15H17NO2S, was synthesized via a substitution reaction between 4-methyl-benzyl-amine and p-toluene-sulfonyl chloride. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules, forming ribbons running along the b-axis direction. One of the aromatic rings hosts two inter-molecular C-H⋯π inter-actions that link these hydrogen-bonded ribbons into a three-dimensional network.
