Bis-(2-bromo-eth-yl)ammonium bromide.

ABSTRACT: The title salt, C(4)H(10)Br(2)N(+)·Br(-), crystallizes with four cations and four anions in the asymmetric unit. In the crystal, the bis-(2-bromo-eth-yl)ammonium cations and bromide anions are linked into chains by N-H?Br hydrogen bonds describing a binary C(2) (1)(4) motif along [010]. Each of these chains is formed by a unique cation and anion pair. The ammonium cations occur in the less preferred anti conformation, characterized by different NCCBr torsion angles. Adjacent chains are linked by weak C-H?Br inter-actions, forming a three-dimensional network. The crystal studied was a pseudo-merohedral twin with twin ratio 0.640?(2):0.360?(2).

Bis-(2-hy-droxy-eth-yl)ammonium 2-bromo-phenolate.

Project description:In the crystal structure of the 1:1 title salt, C(4)H(12)NO(2) (+)·C(6)H(4)BrO(-), hydrogen-bonding inter-actions originate from the ammonium cation, which adopts a syn conformation. A gauche relationship between the C-O and C-N bonds of the 2-hy-droxy-ethyl fragments also facilitates O-H?O inter-actions of bis-(2-hy-droxy-eth-yl)ammonium cation chains to phenolate O atoms. The resulting double-ion chains along [100] are further linked by N-H?O inter-actions, forming chains parallel to [110].

Bis(2-chloro-benz-yl)dimethyl-ammonium bromide.

Project description:In the title compound, C(16)H(18)Cl(2)N(+)·Br(-), the dihedral angle between the aromatic ring planes is 57.73?(5)°. In the absence of any strong hydrogen bonds, the structure results from a large number of competing weaker inter-actions including Cl?Cl [3.4610?(5)?Å] and C-H?Cl contacts and both (aryl) C-H?Br and N(+)-Csp(3)-H?Br(-) cation-anion inter-actions.

Bis(2-hy-droxy-eth-yl)ammonium picrate.

Project description:The asymmetric unit of the title salt, C4H12NO2 (+)·C6H2N3O7 (-), contain two bis-(2-hy-droxy-eth-yl)ammonium cations and two picrate anions. An intra-molecular N-H?O hydrogen bond occurs in each cation. In the crystal, mol-ecules are linked via O-H?O and N-H?O hydrogen bonds, which generate two R 2 (1)(6), an R 2 (2)(10) and an R 2 (2)(13) graph-set ring motifs. There are also a number of C-H?O hydrogen bonds present. The sum of these inter-actions leads to the formation a three-dimensional structure.

Project description:The cation and anion of the title salt, C(14)H(18)N(3)S(2) (+)·ClO(4) (-), lie on a twofold rotation axis. The cation is a W-shaped entity with the aromatic rings at the ends; the ammonium NH(2) (+) group is a hydrogen-bond donor to the pyridyl N atoms. The perchlorate ion has one O atom disordered over two sites in a 0.50:0.50 ratio.

Bis(2,2'-bipyrid-yl)bromidocopper(II) bromide bromo-acetic acid hemihydrate.

Project description:In the title compound, [CuBr(C(10)H(8)N(2))(2)]Br·BrCH(2)COOH·0.5H(2)O, the Cu(II) ion is coordinated by four N atoms [Cu-N = 1.985 (6)-2.125 (7) Å] from two 2,2'-bipyridine ligand mol-ecules and a bromide anion [Cu-Br = 2.471 (2) Å] in a distorted trigonal-bipyramidal geometry. Short centroid-centroid distances [3.762 (5) and 3.867 (5) Å] between the aromatic rings of neighbouring cations suggest the existence of π-π inter-actions. Inter-molecular O-H⋯Br hydrogen bonds and weak C-H⋯O and C-H⋯Br inter-actions consolidate the crystal packing.

Crystal structure of bis-{(<i>S</i>)-1-[2-(di-phenyl-phosphan-yl)ferrocen-yl]-(<i>R</i>)-eth-yl}ammonium bromide di-chloro-methane monosolvate.

Project description:During the synthesis of an FeBr2 complex with the PNP ligand (R,R,SFc,SFc)-[Fe2(C5H5)2(C38H35NP2)] (1), single crystals of the di-chloro-methane monosolvate of the Br- salt of the protonated ligand 1H+ were obtained serendipitously, i.e. [Fe2(C5H5)2(C38H36NP2)]Br·CH2Cl2. The crystal structure of 1H·Br·CH2Cl2 was determined by single-crystal X-ray diffraction. The mean bond lengths in the ferrocene units are Fe-C = 2.049?(3)?Å and C-C = 1.422?(4)?Å within the cyclo-penta-dienyl rings. The mean C-N bond length is 1.523?(4)?Å. The inter-planar angle between the two connected cyclo-penta-dienyl rings is 49.2?(2)°. One ferrocene moiety adopts a staggered conformation, whereas the other is between staggered and eclipsed. The Br- ions and the CH2Cl2 mol-ecules are located in channels extending along <100>. One ammonium H atom forms a hydrogen bond with the Br- ion [H?Br = 2.32?(4)?Å and C-H?Br = 172?(3)°]. The second ammonium H atom is not involved in hydrogen bonding.

2,5-Bis{[(-)-(S)-1-(4-bromo-phen-yl)eth-yl]imino-meth-yl}thio-phene.

Project description:The title compound, C22H20Br2N2S, was synthesized under solvent-free conditions. The mol-ecule shows crystallographic C 2 symmetry, with the S atom of the central thio-phene ring lying on a twofold rotation axis. Furthermore, as a consequence of the (S,S) stereochemistry, the mol-ecule has a twisted conformation. The dihedral angle between the thio-phene and benzene rings is 72.7?(2)° and that between the two benzene rings is 55.9?(2)°. In the crystal, mol-ecules are arranged in a chevron-like pattern, without any significant inter-molecular inter-actions.

Bis(2-{2-[2-(benzyl-carbamo-yl)phen-oxy]acetamido}-eth-yl)ammonium nitrate ethanol disolvate.

Project description:In the title compound, C(36)H(40)N(5)O(6) (+)·NO(3) (-)·2C(2)H(5)OH, the nitrate anion is disordered over the two orientations of equal occupancy while the solvent mol-ecule reveals large displacement parameters. The cation is formed by protonation of the N atom of a secondary amine in the middle of the flexible chain and the whole compound has crystallographically imposed C-2 symmetry with the crystallographic b axis. An O atom of the nitrate anion links the acidic H atoms of the cation via N-H?O hydrogen bonding. In addition, neighbouring cations are connected by inter-molecular N-H?O hydrogen bonds and ?-? inter-actions between the benzamide groups of the cations [centroid-centroid distance = 4.000?(3)?Å], forming a chain along [001]. The ethanol solvent mol-ecules are arranged on the side of the chain through O-H?O hydrogen bonds.
