Crystal structure of (S)-1-O-tert-butyl-diphenyl-silylglycerol: eight chiral mol-ecules in a triclinic cell.

ABSTRACT: The asymmetric unit of the title compound {systematic name: 3-[(tert-butyl-diphenyl-sil-yl)-oxy]propane-1,2-diol, C₁₉H₂₆O₃Si}, contains eight chiral mol-ecules (Z' = 8). These mol-ecules are connected via a complex system of hydrogen bonds into an infinite assembly along the [100] axis; hydro-phobic tert-butyl and phenyl groups form an external coating of the assembly. These assemblies are packed by weak inter-molecular inter-actions in a peculiar formation resembling a 'header bond' masonry brick wall. Disorder of flexible fragments increases with temperature but the same crystal structure exists from 120 to 220 K (and most probably to the melting point at 334 K).

Crystal structure of tert-butyl-diphenyl-phosphine oxide.

Project description:In the structure of the title triorganophosphine oxide, C16H19OP, the P-O bond is 1.490 (1) Å. The P atom has a distorted tetrahedral geometry. The O atom inter-acts with both phenyl groups of a neighboring mol-ecule [C⋯O = 2.930 (3) and 2.928 (4) Å]. The C-O interaction directs an extended supramolecular arrangement along the a-axis.

Crystal structure of a 2:1 piroxicam-gentisic acid co-crystal featuring neutral and zwitterionic piroxicam mol-ecules.

Project description:A new 2:1 co-crystal of piroxicam and gentisic acid [systematic name: 4-hy-droxy-1,1-dioxo-N-(pyridin-2-yl)-2H-1λ6,2-benzo-thia-zine-3-carboxamide-2-(4-oxido-1,1-dioxo-2H-1λ6,2-benzo-thia-zine-3-amido)-pyridin-1-ium-2,5-di-hydroxy-benzoic acid, 2C15H13N3O4S·C7H6O4] has been synthesized using a microfluidic platform and initially identified using Raman spectroscopy. In the co-crystal, one piroxicam mol-ecule is in its neutral form and an intra-molecular O-H⋯O hydrogen bond is observed. The other piroxicam mol-ecule is zwitterionic (proton transfer from the OH group to the pyridine N atom) and two intra-molecular N-H⋯O hydrogen bonds occur. The gentisic acid mol-ecule shows whole-mol-ecule disorder over two sets of sites in a 0.809 (2):0.191 (2) ratio. In the crystal, extensive hydrogen bonding between the components forms layers propagating in the ab plane.

A triclinic polymorph of bis-(μ-di-tert-butyl-phosphanido)bis-[(di-tert-butyl-phosphane)palladium(I)].

Project description:A new polymorph of the title compound, [Pd(2)(C(8)H(18)P)(2)(C(8)H(19)P)(2)], has been found. It belongs to the triclinic P-1 space group, whereas the known form [Leoni, Sommovigo, Pasquali, Sabatino & Braga (1992 ▶), J. Organo-met. Chem.423, 263-270] crystallizes in the monoclinic C2/c space group. The title compound features a dinuclear palladium complex with a planar central Pd(2)(μ-P)(2) core (r.m.s. deviation = 0.003 Å). The Pd-Pd distance of 2.5988 (5) Å is within the range of a Pd(I)-Pd(I) bond. The mol-ecules of both polymorphs are located on a crystallographic centre of inversion. The mol-ecular conformations of the two polymorphs are essentially identical. The crystal packing patterns, on the other hand, are slightly different.

Synthesis and crystal structure of a new hybrid organic-inorganic material containing neutral mol-ecules, cations and hepta-molybdate anions.

Project description:The title compound, hexa-kis-(2-methyl-1H-imidazol-3-ium) hepta-molybdate 2-methyl-1H-imidazole disolvate dihydrate, (C4H7N2)6[Mo7O24]·2C4H6N2·2H2O, was prepared from 2-methyl-imidazole and ammonium hepta-molybdate tetra-hydrate in acid solution. The [Mo7O24]6- hepta-molybdate cluster anion is accompanied by six protonated (C4H7N2)+ 2-methyl-imidazolium cations, two neutral C4H6N2 2-methyl-imidazole mol-ecules and two water mol-ecules of crystallization. The cluster consists of seven distorted MoO6 octa-hedra sharing edges or vertices. In the crystal, the components are linked by N-H⋯N, N-H⋯O, O-H⋯O, N-H⋯(O,O) and O-H⋯(O,O) hydrogen bonds, generating a three-dimensional network. Weak C-H⋯O inter-actions consolidate the packing.

Crystal structure of tert-butyl-N-phenyl-carbonitrilium tetra-chlorido-aluminate.

Project description:In the title compound, (C11H14N)[AlCl4], the nitrilium (systematic name: 2,2-dimethyl-N-phenyl-propane-nitrilium) ion adopts a slightly distorted linear configuration [C-N C = 178.87 (16) and N C-C = 179.13 (17)°]. In the crystal, while there are no inter-molecular hydrogen bonds, pairs of nitrilium ions are linked through π-π inter-actions [inter-centroid distance = 3.8091 (13) Å].

Crystal structure of 1,2-bis-[(2-tert-butyl-phen-yl)imino]-ethane.

Project description:The whole molecule of the title compound, C22H28N2, (I), is generated by inversion symmetry. The mol-ecule is rather similar to that of 2,3-bis-[(2-tert-butyl-phen-yl)imino]-butane, (II), a di-imine ligand comprising similar structural features [Ferreira et al. (2006 ▶). Acta Cryst. E62, o4282-o4284]. Both ligands crystallize with the -N=C(R)-C(R)=N- group around an inversion centre, in a trans configuration. Comparing the two structures, it may be noted that the independent planar groups in both mol-ecules [the central link, -N=C(R)-C(R)=N-, and the terminal aromatic ring] subtend an angle of 69.6 (1)° in (II) and 49.4 (2)° in (I). Ferreira and co-workers proposed that such angle deviation may be ascribed to the presence of two non-classical intra-molecular hydrogen bonds and steric factors. In fact, in (I), similar non-classical hydrogen bonds are observed, and the larger angular deviation in (II) may be assigned to the presence of methyl groups in the di-imino fragment, which can cause steric hindrance due to the presence of bulky tert-butyl substituents in the aromatic rings. The C=N bond lengths are similar in both compounds and agree with comonly accepted values.

Synthesis and crystal structure of 1,3-di-tert-butyl-2-chloro-4,4-diphenyl-1,3,2λ3,4-di-aza-phospha-siletidine.

Project description:The chemical reaction of di-lithium N,N'-di( t but-yl)-Si,Si-di-phenyl-silanedi-amide and PCl3 yielded an off-white solid. Sublimation of the crude product under reduced pressure at elevated temperature gave colourless prismatic crystals of the title compound, C20H28ClN2PSi, which crystallizes in the non-centrosymmetric monoclinic space group Cc. The asymmetric unit of the crystal structure contains one mol-ecule and it is dominated by the central SiN2P four-membered ring, which is almost planar with a mean deviation of the atoms from the best plane of 0.014 Å. The angles between the plane defined by the silicon atom and the two nitro-gen atoms and the best planes of the Si-phenyl groups are 85.1 (2) and 77.4 (2)°, with the tilt of the phenyl rings in the opposite direction. Both tert-butyl groups suffer from a two-position rotational disorder with site occupancies of 0.752 (6)/0.248 (6) and 0.878 (9)/0.122 (9). The P-Cl bond [2.2078 (17) Å] is remarkably elongated compared to the P-Cl distance in PCl3 [2.034 Å; Galy & Enjalbert (1982). J. Solid State Chem. 44, 1-23].

Crystal structure of 4-azido-methyl-6-tert-butyl-2H-chromen-2-one.

Project description:In the title compound, C14H15N3O2, one of the methyl C atoms of the tert-butyl group lies almost in the plane of the chromene ring system [deviation = -0.097 (2) Å], one lies above and one lies below [deviations = 1.460 (3) and 1.006 (3) Å, respectively]. The C-C-N-N torsion angle is 142.33 (17)°. In the crystal, moelcules are linked by weak C-H⋯O hydrogen bonds to generate C(6) chains propagating in the [010] direction.
