Crystal structure of bis-(quinolin-1-ium) tetra-chlorido-ferrate(III) chloride.

ABSTRACT: The asymmetric unit of the title hybrid compound, (C9H8N)[FeCl4]Cl, comprises a tetra-hedral tetra-chlorido-ferrate(III) anion, [FeCl4](-), a Cl(-) anion and two quinolinium cations. There are N-H?Cl hydrogen-bonding inter-actions between the protonated N atoms of the quinolinium cations and the chloride anion, which together with ?-? stacking between adjacent quinolinium rings [centroid-to-centroid distances between C6 and C5N rings in adjacent stacked quinolinium cations of 3.609?(2) and 3.802?(2)?Å] serve to hold the structure together.

Tri-?-chlorido-bis-[(?-hexa-methyl-benzene)-ruthenium(II)] tetra-chlorido-ferrate(III).

Project description:The mol-ecular geometry of the complex cation in the title structure, [(?-Cl)(3){Ru(II)(?(6)-C(6)Me(6))}(2)][Fe(III)Cl(4)], compares very well with that reported earlier for the corresponding PF(6) (-) salt [Pandey et al. (1999 ?). J. Organomet. Chem.592, 278-282]. The [FeCl(4)](-) counter ion has a rather regular tetra-hedral geometry with Fe-Cl distances and Cl-Fe-Cl angles in the range 2.1891?(7)-2.2018?(8)?Å and 107.10?(3)-110.56?(3)°, respectively. There are no significant inter-molecular inter-actions in the crystal except for some weak C-H?Cl contacts, which in turn indicates that the crystal packing is determined predominantly by electrostatic inter-actions between the ionic constituents.

2-Carbamylpyridinium tetra-chlorido-ferrate(III).

Project description:The title compound, (C(6)H(7)N(2)O)[FeCl(4)], contains two carbamylpyridinium (picolinamidinium) cations, which are linked into chains by N(+)-H⋯O hydrogen bonds formed between protonated pyridyl N atoms and carbonyl groups. Tetra-chloridoferrate(III) anions lie between these chains, accepting N-H⋯Cl hydrogen bonds from both H atoms of the picolinamidium -NH(2) group.

Crystal structure of bis-(2-methyl-1H-imidazol-3-ium) tetra-chlorido-cobaltate(II).

Project description:The asymmetric unit of the title compound, (C4H7N2)2[CoCl4], consists of two 2-methyl-imidazolium cations and one tetra-hedral [CoCl4](2-) anion. The anions and cations inter-act through N-H⋯Cl hydrogen bonds to define layers with a stacking direction along [100]. Besides van der Waals forces, weak C-H⋯Cl inter-actions between these layers stabilize the crystal packing.

Crystal structure of metronidazolium tetra-chlorido-aurate(III).

Project description:Metronidazole (MET) [systematic names: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazole and 2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethanol] is a medication that is used to treat infections from a variety of anaerobic organisms. As with other imidazole derivatives, metronidazole is also susceptible to protonation. However, there are few reports of the structures of metronidazolium derivatives. In the title compound, (C6H10N3O3)[AuCl4] [systematic name: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazol-3-ium tetra-chlorido-aur-ate(III)], the asymmetric unit consists of a metronidazolium cation, [H(MET)](+), and a tetra-chlorido-aurate(III) anion, [AuCl4](-), in which the Au(III) ion is in a slightly distorted square-planar coordination environment. In the cation, the nitro group is essentially coplanar with the imidazole ring, as indicated by an O N-C=C torsion angle of -0.2 (4)°, while the hy-droxy-ethyl group is in a coiled conformation, with an O(H)-C-C-N torsion angle of 62.3 (3)°. In the crystal, the anion and cation are linked by an inter-molecular O-H⋯Cl hydrogen bond. In addition, the N-H group of the metronidazolium ion serves as a hydrogen-bond donor to the O atom of the hy-droxy-ethyl group of a symmetry-related mol-ecule, leading to the formation of chains along [010].

Tetra-kis(dihydrogen pefloxacinium) di-μ(2)-chlorido-bis-[tetra-chloridobismuthate(III)] tetra-chloride octa-hydrate.

Project description:The title compound {systematic name: tetra-kis[4-(3-carb-oxy-1-ethyl-6-fluoro-4-hydroxonio-1,4-dihydro-7-quinol-yl)-1-meth-yl-piperazin-1-ium] di-μ(2)-chlorido-bis-[tetra-chlorido-bismuth-ate(III)] tetra-chloride octa-hydrate}, (C(17)H(22)FN(3)O(3))(4)[Bi(2)Cl(10)]Cl(4)·8H(2)O, is composed of edge-shared centrosymmetric dinuclear [Bi(2)Cl(10)](4-) anions, Cl(-) anions, dihydrogen pefloxacinium cations and water mol-ecules. The Bi(III) coordination polyhedron is a distorted octa-hedron. There are four short terminal Bi-Cl bonds [2.5037 (10)-2.6911 (7) Å] and two longer bridging bonds [2.8834 (8) and 3.0687 (9) Å] in each octa-hedron. Two sets of chloride ions and water mol-ecules are disordered over the same sites with site occupancies of 1/3 and 2/3, respectively. Anions, cations and water mol-ecules are linked by O-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds, forming a three-dimensional framework. There are also π-π stacking inter-actions between quinoline ring systems [centroid-centroid distance = 3.575 (1) Å].

Crystal structure of trans-di-chlorido-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?4 N)chromium(III) bis-(form-amide-?O)(1,4,8,11-tetra-aza-cyclo-tetra-decane-?4 N)chromium(III) bis-[tetra-chlorido-zincate(II)].

Project description:The structure of the title compound, [CrCl2(C10H24N4)][Cr(HCONH2)2(C10H24N4)][ZnCl4]2 (C10H24N4 = 1,4,8,11-tetra-aza-cyclo-tetra-decane, cyclam; HCONH2 = formamide, fa), has been determined from synchrotron X-ray data. The asymmetric unit contains two independent halves of the [CrCl2(cyclam)]+ and [Cr(fa)(cyclam)]3+ cations, and one tetra-chlorido-zincate anion. In each complex cation, the CrIII ion is coordinated by the four N atoms of the cyclam ligand in the equatorial plane and two Cl ligands or two O-bonded formamide mol-ecules in a trans axial arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry. The Cr-N(cyclam) bond lengths are in the range 2.061?(2) to 2.074?(2)?Å, while the Cr-Cl and Cr-O(fa) bond distances are 2.3194?(7) and 1.9953?(19)?Å, respectively. The macrocyclic cyclam moieties adopt the centrosymmetric trans-III conformation with six- and five-membered chelate rings in chair and gauche conformations. The crystal structure is stabilized by inter-molecular hydrogen bonds involving the NH or CH groups of cyclam and the NH2 group of coordinated formamide as donors, and Cl atoms of the ZnCl4 2- anion as acceptors.
