Crystal structure of a new polymorph of di(thio-phen-3-yl) ketone.

Project description:The crystal structure of the title compound, C9H6OS2, represents a new polymorph. The crystal structure was solved in the ortho-rhom-bic space group Pbcn with one half of the mol-ecule in the asymmetric unit. The thio-phene rings are perfectly planar and twisted with respect to each other, showing the mol-ecule to be in an S,O-trans/S,O-trans conformation. In the crystal, C-H⋯O hydrogen bonds connect the mol-ecules into layers extending parallel to the ab plane. The crystal structure also features π-π inter-actions.

Crystal structure of 8-hy-droxy-quinoline: a new monoclinic polymorph.

Project description:In an attempt to grow 8-hy-droxy-quinoline-acetamino-phen co-crystals from equimolar amounts of conformers in a chloro-form-ethanol solvent mixture at room temperature, the title compound, C9H7NO, was obtained. The mol-ecule is planar, with the hy-droxy H atom forming an intra-molecular O-H?N hydrogen bond. In the crystal, mol-ecules form centrosymmetric dimers via two O-H?N hydrogen bonds. Thus, the hy-droxy H atoms are involved in bifurcated O-H?N hydrogen bonds, leading to the formation of a central planar four-membered N2H2 ring. The dimers are bound by inter-molecular ?-? stacking [the shortest C?C distance is 3.2997?(17)?Å] and C-H?? inter-actions into a three-dimensional framework. The crystal grown represents a new monoclinic polymorph in the space group P21/n. The mol-ecular structure of the present monoclinic polymorph is very similar to that of the ortho-rhom-bic polymorph (space group Fdd2) studied previously [Roychowdhury et al. (1978 ?). Acta Cryst. B34, 1047-1048; Banerjee & Saha (1986 ?). Acta Cryst. C42, 1408-1411]. The structures of the two polymorphs are distinguished by the different geometries of the hydrogen-bonded dimers, which in the crystal of the ortho-rhom-bic polymorph possess twofold axis symmetry, with the central N2H2 ring adopting a butterfly conformation.

Crystal structure and Hirshfeld surface analysis of new polymorph of racemic 2-phenyl-butyramide.

Project description:A new polymorph of the title compound, C10H13NO, was obtained by recrystallization of the commercial product from a water/ethanol mixture (1:1 v/v). Crystals of the previously reported racemic and homochiral forms of 2-phenyl-butyramide were grown from water-aceto-nitrile solution in 1:1 volume ratio [Khrustalev et al. (2014 ▸). Cryst. Growth Des. 14, 3360-3369]. While the previously reported racemic and enanti-opure forms of the title compound adopt very similar supra-molecular structures (hydrogen-bonded ribbons), the new racemic polymorph is stabilized by a single N-H⋯O hydrogen bond that links mol-ecules into chains along the c-axis direction with an anti-parallel (centrosymmetric) packing in the crystal. Hirshfeld mol-ecular surface analysis was employed to compare the inter-molecular inter-actions in the polymorphs of the title compound.

Crystal structure of 2,4-di-nitro-phenyl 4-methyl-benzene-sulfonate: a new polymorph.

Project description:The title compound, C13H10N2O7S, was synthesized via a nucleophilic substitution reaction between 2,4-di-nitro-phenol and p-toluene-sulfonyl chloride. This crystal structure is a polymorph of CSD entry WUVYUH [Vembu et al. (2003). Acta Cryst, E59, o378-380]. The aromatic substituents on the sulfonate group are oriented gauche to one another with a C-O-S-C torsion angle of -62.0 (3)°. The supra-molecular features that contribute to the crystal stability are offset π-π [centroid-centroid distance = 3.729 (2) Å] and multiple C-H⋯O inter-actions.

Crystal structure of a new polymorph of 3-acetyl-8-meth-oxy-2H-chromen-2-one.

Project description:A new polymorphic form of the title compound, C12H10O4, is described in the ortho-rhom-bic space group Pbca and Z = 8, as compared to polymorph I, which crystallizes in the monoclinic space group C2/c and Z = 8 [Li et al. (2012). Chin. J. Struct. Chem. 31, 1003-1007.]. In polymorph II, the coumarin ring system is almost planar (r.m.s. deviation = 0.00129?Å). In the crystal, mol-ecules are connected by Csp 3-H?O and Car-H?O hydrogen bonds, forming mol-ecular sheets linked into zigzag shaped layers along the b-axis direction. The three-dimensional lattice is assembled through stacking of the zigzag layers by ?-? inter-actions with a centroid-to-centroid distance of 3.600?(9)?Å and anti-parallel C=O?C=O inter-actions with a distance of 3.1986?(17)?Å, which give rise to a helical supra-molecular architecture.

Crystal structure of a new hydrate form of the NSAID sodium diclofenac.

Project description:The crystal structure is reported of sodium 2-[2-(2,6-di-chloro-anilino)phen-yl]acetate 3.5-hydrate or tetra-?-aqua-?8 O:O-deca-aqua-bis-{?3-2-[2-(2,6-di-chloro-anilino)phen-yl]acetato-?3 O:O:O}tetra-sodium(I) bis-{2-[2-(2,6-di-chloro-anil-ino)phen-yl]acetate}, {[Na4(C14H10Cl2NO2)2(H2O)14](C14H10Cl2NO2)2} n , which re-presents a new hydrate form of the NSAID sodium diclofenac (SD). The triclinic unit cell contains one ionic compound with formula Na4(C14H10Cl2NO2)4(H2O)14, in which two symmetry-related carboxyl-ate anions C14H10Cl2NO2 - are bonded to a centrosymmetric [Na4]4+ core cationic cluster, while the others are only hydrogen bonded to the cationic cluster. The conformation for the anions is similar to that found in other diclofenac compounds, and the [Na4(Ocarbox)2(H2O)14]4+ cluster displays an unprecedented geometry, which can be described as an incomplete dicubane cluster formed by face-sharing incomplete cubes. A complex framework of O-H?O hydrogen bonds stabilizes the crystal structure. The herein reported crystal structure for SD·3.5H2O in space group P is different from those previously reported for other hydrates, namely SD·4.75H2O (P21) and SD·5H2O (P21/m).

Crystal structure of a new monoclinic polymorph of N-(4-methyl-phen-yl)-3-nitro-pyridin-2-amine.

Project description:The title compound, C12H11N3O2, is a second monoclinic polymorph (P21, with Z' = 4) of the previously reported monoclinic (P21/c, with Z' = 2) form [Akhmad Aznan et al. (2010 ?). Acta Cryst. E66, o2400]. Four independent mol-ecules comprise the asymmetric unit, which have the common features of a syn disposition of the pyridine N atom and the toluene ring, and an intra-molecular amine-nitro N-H?O hydrogen bond. The differences between mol-ecules relate to the dihedral angles between the rings which range from 2.92?(19) to 26.24?(19)°. The geometry-optimized structure [B3LYP level of theory and 6-311?g+(d,p) basis set] has the same features except that the entire mol-ecule is planar. In the crystal, the three-dimensional architecture is consolidated by a combination of C-H?O, C-H??, nitro-N-O?? and ?-? inter-actions [inter-centroid distances = 3.649?(2)-3.916?(2)?Å].

A new crystal form of GABARAPL2.

Project description:The Atg8 protein family comprises the GABA type A receptor-associated proteins (GABARAPs) and microtubule-associated protein 1 light chains 3 (MAP1LC3s) that are essential mediators of autophagy. The LC3-interacting region (LIR) motifs of autophagy receptors and adaptors bind Atg8 proteins to promote autophagosome formation, cargo recruitment, and autophagosome closure and fusion to lysosomes. A crystal structure of human GABARAPL2 has been published [PDB entry 4co7; Ma et al. (2015), Biochemistry, 54, 5469-5479]. This was crystallized in space group P21 with a monoclinic angle of 90° and shows a pseudomerohedral twinning pathology. This article reports a new, untwinned GABARAPL2 crystal form, also in space group P21, but with a 98° monoclinic angle. No major conformational differences were observed between the structures. In the structure described here, the C-terminal Phe117 binds into the LIR docking site (LDS) of a neighbouring molecule within the asymmetric unit, as observed in the previously reported structure. This crystal contact blocks the LDS for co-crystallization with ligands. Phe117 of GABARAPL2 is normally removed during biological processing by Atg4 family proteases. These data indicate that to establish interactions with the LIR, Phe117 should be removed to eliminate the crystal contact and liberate the LDS for co-crystallization with LIR peptides.

Crystal structure of a new polymorph of (2S,3S)-2-amino-3-methyl-penta-noic acid.

Project description:A new polymorph of (2S,3S)-2-amino-3-methyl-penta-noic acid, l-isoleucine C6H13NO2, crystallizes in the monoclinic space group P21 with four independent mol-ecules in the asymmetric unit. The mol-ecules are zwitterions. In the crystal, N-H?O hydrogen bonds link two pairs of independent mol-ecules and their symmetry-related counterparts to form two types of layers stacked in an anti-parallel manner parallel to (001). The hydro-phobic aliphatic isopropyl groups protrude from these layers.

Synthesis and crystal structure of a new polymorph of potassium europium(III) bis(sulfate) mono-hydrate, KEu(SO4)2·H2O.

Project description:The mixed-metal sulfate, KEu(SO4)2·H2O, has been obtained as a new polymorph using hydro-thermal conditions. The crystal structure is isotypic with NaCe(SO4)2·H2O and shows a three-dimensional connectivity of the tetra-hedral sulfate units with EuIII and KI ions. Tricapped trigonal-prismatic EuO9 units and square-anti-prismatic KO8 units link the SO4 tetra-hedra, building the three-dimensional structure. Topological analysis reveals the existence of two nodes with 6- and 10-connected nets. The compound was previously reported [Kazmierczak & Höppe (2010 ?). J. Solid State Chem.183, 2087-2094] in the monoclinic space group P21/c with a similar structural connectivity and coordination environments to the present compound.
