Ethidium hepta-fluoro-butyrate.

ABSTRACT: In the title compound (systematic name: 3,8-diamino-5-ethyl-6-phenylphenanthridin-5-ium 2,2,3,3,4,4,4-heptafluorobutyrate), C₂₁H₂₀N₃ ⁺·C₄F₇O₂ ^-, two ethidium ions, C₂₁H₂₀N₃ ⁺ form a dimerized structure due to π-π inter-actions, even though they are positively charged. The hepta-fluoro-butyrate anions are connected to neighbouring cation dimers via hydrogen-bonding inter-actions, the hydrogen-bonding donor sites of the -NH₂ groups of the ethidium ions connecting to the hydrogen-bonding acceptor sites of the -COO^- groups of the hepta-fluoro-butyrate anions.

N,N'-Bis(2,2,3,3,4,4,4-hepta-fluoro-butyl)naphthalene-1,4:5,8-tetra-carboximide.

Project description:The title mol-ecule, C(22)H(8)F(14)N(2)O(4), lies across a crystallographic inversion center with the naphthalene diimide core essentially planar (mean deviation from plane is 0.0583 Å). The CF(2) groups in the perfluorobutyl chains are in an energetically favorable all trans conformation. In the crystal structure, mol-ecules are packed in slightly displaced layers so that the side chains overlap the aromatic naphthalene diimide rings, thus minimizing any possible π-π overlap.

Crystal structure of 1-hepta-fluoro-tolyl-closo-1,2-dicarbadodeca-borane.

Project description:The mol-ecular structure of the title compound 1-(2',3',5',6'-tetra-fluoro-4'-trifluoro-methyl-phen-yl)-closo-1,2-dicarbadodeca-borane, C9H11B10F7, features an intra-molecular ortho-F⋯H2 hydrogen bond [2.11 (2) Å], which is responsible for an orientation of the hepta-fluoro-tolyl substituent in which the plane of the aryl ring nearly eclipses the C1-C2 cage connectivity.

Crystal structure of aqua-bis-(hepta-fluoro-butano-ato-κO)(1,10'-phenanthroline-κ(2) N,N')copper(II).

Project description:The title compound, [Cu(C4F7O2)2(C12H8N2)(H2O)], is mononuclear and contains a penta-coordinated Cu(II) ion. The geometry of Cu(II) ion can be described as distorted square-pyramidal with two O atoms of two butano-ate anions and two N atoms of the o-phenanthroline ligand occupying the basal plane, and a water O atom located at the axial position. In the crystal, C-H⋯(O,F) and O-H⋯(O,F) hydrogen bonds and π-π inter-actions [centroid-to-centroid distance 3.533 (2) Å] link the mol-ecules into a three-dimensional supra-molecular structure.

Benzylammonium hepta-noate-hepta-noic acid (1/1).

Project description:The title salt, C7H10N(+)·C7H13O2(-)·C7H14O2, is an unusual 2:1 stoichiometric combination of two carb-oxy-lic acid mol-ecules and one amine. Although there are crystal structures of a number of 1:1 complexes reported in the literature, 2:1 acid amine complexes are rather uncommon. In this case, a proton is transferred between one acid mol-ecule and the amine to give an acid anion and an ammonium cation whilst the other carb-oxy-lic acid remains protonated. The species inter-act strongly via electrostatic forces and hydrogen bonds. In addition we note that the N atom of the ammonium group makes four close contacts to surrounding O atoms. Three of these are hydrogen bonds with neighbouring acid anions while the fourth does not involve a hydrogen atom but is directed towards the carbonyl O atom of the protonated acid. Each of the acid anion O atoms accepts two hydrogen bonds from adjacent N atoms. There is also evidence of short C-H⋯O contacts. There is disorder (occupancy ratio 0.51:0.49) in the alkyl chain of one of the carb-oxy-lic acid mol-ecules.

Ethidium tetra-phenyl-borate aceto-nitrile disolvate.

Project description:In the title solvated salt, (C21H20N3){B(C6H5)4}·2CH3CN (systematic name 3,8-di-amino-5-ethyl-6-phenyl-phenanthridin-5-ium tetra-phenyl-borate aceto-nitrile disolvate), the dihedral angle between the tricyclic fused ring system (r.m.s. deviation = 0.021 Å) and the pendant phenyl group of the ethidium cation is 84.91 (7)°. The {B(C6H5)4}- anion has a typical tetra-hedral structure. The aceto-nitrile solvent mol-ecules do not accept hydrogen bonds from the -NH2 groups of the ethidium ions.

Didysprosium hepta-nickel.

Project description:The title compound, Dy(2)Ni(7), adopts the β-Gd(2)Co(7)-type structure type. The asymmetric unit contains two Dy sites (both site symmetry 3m) and five Ni sites (site symmetries .m, .2/m and -3m, and two 3m). The four different Ni coordination polyhedra are Frank-Kasper icosa-hedra formed by five Dy and seven Ni atoms, four Dy and eight Ni, three Dy and nine Ni, and six Dy and six Ni atoms, respectively. The two different Dy coordination polyhedra are either pseudo Frank-Kasper icosa-hedra formed by two Dy and 18 Ni atoms or normal Frank-Kasper icosa-hedra formed by four Dy and 12 Ni atoms.

The killing of African trypanosomes by ethidium bromide.

Project description:Introduced in the 1950s, ethidium bromide (EB) is still used as an anti-trypanosomal drug for African cattle although its mechanism of killing has been unclear and controversial. EB has long been known to cause loss of the mitochondrial genome, named kinetoplast DNA (kDNA), a giant network of interlocked minicircles and maxicircles. However, the existence of viable parasites lacking kDNA (dyskinetoplastic) led many to think that kDNA loss could not be the mechanism of killing. When recent studies indicated that kDNA is indeed essential in bloodstream trypanosomes and that dyskinetoplastic cells survive only if they have a compensating mutation in the nuclear genome, we investigated the effect of EB on kDNA and its replication. We here report some remarkable effects of EB. Using EM and other techniques, we found that binding of EB to network minicircles is low, probably because of their association with proteins that prevent helix unwinding. In contrast, covalently-closed minicircles that had been released from the network for replication bind EB extensively, causing them, after isolation, to become highly supertwisted and to develop regions of left-handed Z-DNA (without EB, these circles are fully relaxed). In vivo, EB causes helix distortion of free minicircles, preventing replication initiation and resulting in kDNA loss and cell death. Unexpectedly, EB also kills dyskinetoplastic trypanosomes, lacking kDNA, by inhibiting nuclear replication. Since the effect on kDNA occurs at a >10-fold lower EB concentration than that on nuclear DNA, we conclude that minicircle replication initiation is likely EB's most vulnerable target, but the effect on nuclear replication may also contribute to cell killing.

Project description:The asymmetric unit of the title compound, C(11)H(14)N(2)O(2), contains one half-mol-ecule as the central C atom of the mol-ecule lies on a twofold rotation axis. In the crystal structure, weak inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into zigzag chains along c.

Benzyl-ammonium hepta-noate.

Project description:The title 1:1 stoichiometric salt, C7H10N(+)·C7H13O2 (-), is formed by proton transfer between hepta-noic acid and benzyl-amine. This combination contrasts to the recently published 2:1 acid-amine adduct of cation, anion and neutral acid molecule from the same components [Wood & Clarke (2013 ▶). Acta Cryst. E69, o346-o347]. There are N-H⋯O hydrogen bonds of moderate strength in the structure [the most important graph-set motifs are R (2) 4(8) and R (4) 4(12)], as well as weak C-H⋯O inter-actions.

Crystal structure of hepta-guanidinium nona-hydrogen bis-[α-hexa-molybdoplatinate(IV)] hepta-hydrate.

Project description:The title compound, (CH6N3)7H9[PtMo6O24]2·7H2O, containing the well-known Anderson-type heteropolyoxomolybdate, was obtained by recrystallization of its powdered guanidinium salt. The protonated O atoms in the polyanion were confirmed by electron-density maps, inter-polyanion hydrogen bonds and bond-valance sums (BVS). The {[H4.5PtMo6O24]2}(7-) polyanion is the same as that already characterized in K7[H4.5PtMo6O24]2·11H2O [space group P-1; Lee & Joo (2010 ▶). Acta Cryst. E66, i8-i9]. The heteropolyanions form inversion-generated dimers, {[H4.5PtMo6O24]2}(7-), held together by each of the four μ3-O-H⋯μ1-O, two μ2-O-H⋯μ2-O hydrogen bonds and one centrosymmetric μ3-O-H-μ3-O hydrogen bond. The H atom of the centrosymmetric hydrogen bond is located on an inversion centre. One guanidinium ion and one water mol-ecule are equally disordered about a twofold rotation axis.
