Darifenacin hydro-bromide.

ABSTRACT: In the title compound {systematic name: (S)-3-[(aminocar-bonyl)diphenylmethyl]-1-[2-(2,3-di-hy-dro-benzofuran-5-yl)ethyl]pyrrolidinium bromide}, C(28)H(31)N(2)O(2) (+)·Br(-), the pyrrolidine rings adopts an envelope conformation. The two phenyl rings make a dihedral angle of 72.5?(1)°. The four coplanar atoms of the pyrrolidine ring makes dihedral angles of 33.1?(2) and 82.8?(2)° with the two phenyl rings. The mol-ecular conformation is influenced by a C-H?O inter-action. In the crystal packing, there are two N-H?Br hydrogen bonds running in opposite directions. They appear to form C(10) and C(9) chain motifs in the unit cell. In addition, the mol-ecular packing is further stabilized by C-H?Br and C-H?O hydrogen bonds. The C atom bonded to the benzofuran ring system is disordered in a 0.66:0.34 ratio.

Bupropion hydro-bromide propanol hemisolvate.

Project description:The title compound {systematic name: N-[1-(3-chloro-phen-yl)-1-oxopropan-2-yl]-tert-butanaminium bromide propanol hemisolvate}, C(13)H(19)ClNO(+)·Br(-)·0.5C(3)H(8)O, crystallizes with two independent bupropion hydro-bromide ion pairs and a solvent 1-propanol mol-ecule in the asymmetric unit. In both mol-ecules, the expected proton transfer from HBr to the amino group of the bupropion mol-ecule is observed, and intra- and inter-molecular N-H?Br hydrogen-bond inter-actions are formed. These inter-actions link the mol-ecules into hydrogen-bond dimers. The side chains of the two cations have slightly different orientations. The 1-propanol solvent mol-ecule is linked to a bromide ion by an O-H?Br hydrogen bond.

Redetermination of l-tryptophan hydro-bromide.

Project description:The redetermined crystal structure of the title compound, C(11)H(13)N(2)O(2) (+)·Br(-), is reported. Data collection at 100?K about three crystallographic axes resulted in a crystal structure with significantly higher precision in comparison to the two-dimensional data collected at 176?K [Takigawa et al. [(1966) Bull. Chem. Soc. Jpn, 39, 2369-2378]. The carboxyl group and indole ring system are planar, with maximum deviations of 0.002?(2) and 0.007?(2)?Å, respectively, and make an angle of 70.17?(1)° with each other. The mol-ecules are arranged in double layers of carboxyl and amino groups parallel to the ab plane, stabilized by an extensive network of N-H?Br and O-H?Br hydrogen bonds. The polar layer is held together by a network of three N-H?Br hydrogen bonds and one O-H?Br hydrogen bond. In the non-polar layer, the indole rings are linked mainly by electrostatic N-H?C inter-actions between the polarized bond N-H (H is ?(+)) of the pyrrole unit and two of the ring C atoms (?(-)) of the benzene rings of adjacent mol-ecules. The distances of these electrostatic inter-actions are 2.57 and 2.68?Å, respectively. C-H?O and C-H?? inter-actions are also present.

(S)-2-Oxotetra-hydro-furan-3-aminium bromide.

Project description:In the title HBr salt of (S)-homoserine lactone, C(4)H(8)NO(2) (+)·Br(-), the five-membered ring has an envelope conformation, with the -CH(2)- C atom adjacent to the N-substituted C atom at the flap position. The four-atom mean plane (r.m.s. deviation = 0.005 Å) of the envelope forms a dihedral angle of 32.12 (9)° with the three-atom flap plane. The distorted square-pyramidal coordination about the anion involves five surrounding cations, with the square base defined by three N-H⋯Br hydrogen bonds [Br⋯N = 3.3046 (10), 3.3407 (12) and 3.3644 (13) Å] and near-contact with an H atom attached to C [Br⋯C = 3.739 (1) Å]. Another Br⋯C contact of 3.427 (1) Å defines the apex. There is also an N-H⋯O hydrogen bond present linking the cations.

1-Benzyl-2-dimethyl-amino-3-methyl-3,4,5,6-tetra-hydro-pyrimidin-1-ium bromide.

Project description:In the title molecular salt, C(14)H(22)N(3) (+)·Br(-), the ring incorporating the guanidinium grouping exhibits a half-chair conformation and the dihedral angle between the N-C-N and C-C-C planes is 55.0?(3)°. The C-N bond lengths in the central CN(3) unit are 1.333?(4), 1.338?(3) and 1.341?(4)?Å, indicating partial double-bond character. The central C atom is bonded to the three N atoms in a nearly ideal trigonal-planar geometry and the positive charge is delocalized in the CN(3) plane. The distances between the N atom and the terminal methyl C atoms [1.453?(4)-1.461?(4)?Å] are all close to a typical single C-N bond length.

Project description:X-ray crystallographic analysis of the title hydro-bromide salt, C(10)H(20)N(+)·Br(-), of (1R,2S,3R,5R,8aR)-3-hydroxy-meth-yl-5-methyl-octa-hydro-indolizine-1,2-diol defines the absolute and relative stereochemistry at the five chiral centres in steviamine, a new class of polyhydroxy-lated indolizidine alkaloid isolated from Stevia rebaudiana (Asteraceae) leaves. In the crystal structure, mol-ecules are linked by inter-molecular O-H?Br and N-H?Br hydrogen bonds, forming double chains around the twofold screw axes along the b-axis direction.

Crystal structure and Hirshfeld surface analysis of a pyridiniminium bromide salt: 1-[2-([1,1'-biphen-yl]-4-yl)-2-oxoeth-yl]-3-methyl-1,4-di-hydro-pyridin-4-iminium bromide.

Project description:In the cation of the title salt, C20H19N2O+·Br-, the phenyl rings are inclined to one another by 38.38 (8)°, whereas the central phenyl ring and the pyridiniminium ring are almost perpendicular with a dihedral angle of 87.37 (9)°. The N+=C cationic double bond was verified by the shortened bond length of 1.337 (2) Å. In the crystal, the Br- anion is linked to the cation by an N-H⋯Br hydrogen bond. C-H⋯O hydrogen bonds link adjacent pyridiniminium cations into inversion dimers with an R22(18) graph-set motif. These dimers are stacked in a phen-yl-phenyl T-shaped geometry through C-H⋯π inter-actions. A Hirshfeld surface analysis was conducted to verify the contributions of the different inter-molecular inter-actions.

Crystal structure of 2-amino-1,3-di-bromo-6-oxo-5,6-di-hydro-pyrido[1,2-a]quinoxalin-11-ium bromide monohydrate.

Project description:In the title hydrated salt, C12H8Br2N3O(+)·Br(-)·H2O, which was synthesized by the reaction of the pyridine derivative Schiff base N (1),N (4)-bis-(pyridine-2-yl-methyl-ene)benzene-1,4-di-amine with bromine, the asymmetric unit contains a 2-amino-1,3-di-bromo-6-oxo-5,6-di-hydro-pyrido[1,2-a]quinoxalin-11-ium cation, with a protonated pyridine moiety, a bromide anion and a water mol-ecule of solvation. The cation is non-planar with the di-bromo-substituted benzene ring, forming dihedral angles of 24.3?(4) and 11.5?(4)° with the fused pyridine and pyrazine ring moieties, respectively. In the crystal, the cations are linked through a centrosymmetric hydrogen-bonded cyclic R 4 (2)(8) Br2(H2O)2 unit by N-H?Br, N-H?O and O-H?Br hydrogen bonds, forming one-dimensional ribbons extending along b, with the planes of the cations lying parallel to (100).

Crystal structure of tris-(1,3-dimesityl-4,5-di-hydro-1H-imidazol-3-ium) tetra-bromido-cobaltate(II) bromide chloro-form hexa-solvate.

Project description:In the unit cell of the title compound, (C21H27N2)3[CoBr4]Br·6CHCl3, the tetrabromidocobaltate(II) anion and the bromide anion are located on a crystallographic threefold rotation axis. For the [CoBr4](2-) group, the axis runs through one of the Br ligands and the Co(II) atom. All other structure moieties lie on general sites. Various tris-(1,3-dimesityl-4,5-di-hydro-1H-imidazol-3-ium) structures with different counter-ions have been reported. In the title compound, the N-C-N angle is 113.7 (5)°, with short C-N bond lengths of 1.297 (7) and 1.307 (7) Å. The two mesityl planes make a dihedral angle of 34.6 (1)° and the dihedral angles between the mesityl and N-C-N planes are 82.0 (1) and 88.5 (1)°, respectively. The imidazoline ring is almost planar, with atom deviations in the range 0.003 (5)-0.017 (5) Å from the best plane; the mean deviation is 0.012 (5) Å. In the crystal, non-covalent inter-actions of the C-H⋯Br type occur between the Br(-) anion and the cation, as well as between the [CoBr4](2-) anion and both the chloro-form solvent mol-ecules. These H⋯A distances are slightly shorter than the sum of van der Waals radii.
