Acta Crystallographica Section EStructure Reports Online was launched in January 2001 as the IUCr's first electronic-only journal. It is a rapid communication journal for the publication of concise reports on inorganic, metal-organic and organic structures, and benefits from an enhanced electronic publication procedure. Each published report includes a set of key indicators, giving a summary of the main descriptors of the precision and completeness of the study, with indications of problems such as disorder. The publication...4-(E)-Phenyliminomethylbenzonitrile- April 2, 2008 In the molecule of the title compound, C14H10N2, the two aromatic rings are oriented at a dihedral angle of 32.22(6). In the crystal structure, intermolecular CH...N hydrogen bonds link the molecules into centrosymmetric R22(10) dimers. A weak interaction between the cyanobenzene rings, with a centroidcentroid distance of 3.8447(3), further stabilizes the crystal structure. There is also a CH... interaction between the aniline ring and a CH group of the cyanobenzene ring.http://scripts.iucr.org/cgi-bin/paper?hk2445 Bis(chloroacetato)-2O,O;O-methanol-O-bis(2-methylfuro3,2-cpyridine-N)copper(II)- April 2, 2008 In the title compound, Cu(C2H2ClO2)2(C8H7NO)2(CH4O), the Cu2+ ion has a highly distorted square-bipyramidal (4+1+1) coordination environment and is bonded to three carboxylate O atoms of two chloroacetate anions (monodentate and asymmetrically bidentate), two pyridine N atoms of 2-methylfuro3,2-cpyridine and one methanol O atom. There is an intramolecular OH...O hydrogen bond. Intermolecular CH...O hydrogen bonds result in the formation of a three-dimensional network and stacking interactions..http://scripts.iucr.org/cgi-bin/paper?om2220 (E)-2-N-Ethyl-4-(4-nitrophenyl)diazenylanilinoethyl acrylate- April 2, 2008 In the molecule of the title compound, C19H20N4O4, the rings are almost coplanar, forming a dihedral angle of 0.76(3). In the crystal structure, intermolecular CH...O hydrogen bonds link the molecules.http://scripts.iucr.org/cgi-bin/paper?hk2424 1,2-Bis(N-benzoylthioureido)benzene- April 2, 2008 The title compound, C22H18N4O2S2, was characterized by 1H and 13C NMR, solid-state IR spectroscopy and X-ray crystallographic techniques. The crystal structure determination reveals that the twisting modes of the two side arms are different CNCO and CNCN torsion angles = 1.2(3) and 1.1(3), respectively, in one arm and 24.1(3) and 5.1(3), respectively, in the other. The crystal structure involves NH...O and NH...S hydrogen bonds.http://scripts.iucr.org/cgi-bin/paper?ww2115 1-(4-Hydroxy-2-methyl-1,1-dioxo-2H-1,2-benzothiazin-3-yl)ethanone- April 2, 2008 In the title compound, C11H11NO4S, the thiazine ring adopts a distorted half-chair conformation. The enolic H atom is involved in an intramolecular OH...O hydrogen bond, forming a six-membered ring. Molecules are linked through weak intermolecular CH...O hydrogen bonds, resulting in chains lying along the b axis.http://scripts.iucr.org/cgi-bin/paper?pv2072 Tetraaquabis(biuret-2O,O)gadolinium(III) trichloride- April 2, 2008 In the title compound, Gd(C2H5N3O2)2(H2O)4Cl3, which is isostrucutural with its yttrium analogue, the Gd3+ ion (site symmetry 2) is bonded to eight O atoms (arising from two O,O-bidentate biuret molecules and four water molecules) in a distorted square-antiprismatic arrangement. A network of NH...O, NH...Cl and OH...Cl hydrogen bonds helps to establish the packing, leading to a three-dimensional network. One of the chloride ions has site symmetry 2.http://scripts.iucr.org/cgi-bin/paper?sg2230 3-(3,5-Dichloroanilinocarbonyl)propionic acid- April 2, 2008 The crystal structure of the title compound, C10H9Cl2NO3, consists of dimers due to intermolecular OH...O hydrogen bonding forming an R22(8) ring through the carboxyl groups. These dimers are linked to each other by intermolecular hydrogen bonds between the amine group and the adjacent carbonyl O atom. A single CCl... interaction is also observed between the chloro-substituted aromatic rings.http://scripts.iucr.org/cgi-bin/paper?fj2109 Low-temperature phase of hexaguanidinium heptamolybdate monohydrate- April 2, 2008 The crystal structure of the title compound, C(NH2)36Mo7O24H2O, previously determined at room temperature in the monoclinic space group C2c from Weissenberg techniques Don & Weakley (1981). Acta Cryst. B37, 451453, has been redetermined from low-temperature single-crystal data in the monoclinic space group P21c. The asymmetric unit contains one heptamolybdate anion, six guanidinium cations and one water molecule of hydration. The anions and cations are linked by an extensive network of...http://scripts.iucr.org/cgi-bin/paper?mg2049 N-Methyl-1-oxoisoindoline-2-carboxamide monohydrate- April 2, 2008 The title compound, C10H10N2O2H2O, is dimerized by inversion-related intermolecular NH...O hydrogen bonding. There is an intramolecular NH...O bond, resulting in a six-membered ring. Each dimer interacts with other dimers through hydrogen bonding with water molecules. The water molecules are linked to each other in a stair-like chain, thus generating two-dimensional polymeric strips. The dimers are also linked to each other through intermolecular CH...O hydrogen bonding. There are interactions.http://scripts.iucr.org/cgi-bin/paper?bq2071 Decacarbonyl-13C,23C,34C--hydrido-1:22H:H-(-quinoline-2-thiolato-1:22S:S)diosmium(I)osmium(0)(3 OsOs)- April 2, 2008 The title compound, Os3(C9H6NS)H(CO)10, contains a nearly equilateral triangle of Os atoms. Two of the Os atoms are bridged by an S atom of the quinoline-2-thiolate ligand. Ten carbonyl groups complete the cluster, resulting in a distorted octahedral geometry for each Os atom. The hydride atom, which was located in a difference Fourier map and refined isotropically, bridges the shortest OsOs edge.http://scripts.iucr.org/cgi-bin/paper?hy2117 |
