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.
Project description:The asymmetric unit of the title salt, (C8H10N3)[FeCl4], contains one 1,3-dimethyl-1H-1,2,3-benzotriazol-3-ium cation and one tetra-chloridoferrate anion. The Fe(III) atom in the anion is tetra-hedrally coordinated by four Cl atoms. In the crystal, inter-actions are observed between the Cl atoms and the triazolium ring [Cl?centroid distances = 3.587?(3) and 3.866?(3)?Å].
Project description:The title salt, (C7H11N2)[FeCl4], consists of one essentially planar (the r.m.s. deviation for all non-H atoms being 0.004?Å) 4-(dimethyl-amino)-pyridinium cation and a tetra-hedral tetra-chloridoferrate(III) anion. The cations and anions are arranged in layers parallel to (010). Besides electrostatic inter-actions, the crystal packing features N-H?Cl and C-H?Cl hydrogen bonds between cations and anions, forming a three-dimensional network.
Project description:The asymmetric unit of the title compound, (C(13)H(17)N(2)O)(2)[ZnCl(4)]·2H(2)O, contains two tetra-hydro-harmine cations, one tetra-chloro-zincate(II) anion and two water mol-ecules. In the cations, the two 1H-indole ring systems are essentially planar, with maximum deviations of 0.016?(2) and 0.018?(2)?Å, and both tetra-hydro-pyridinium rings show a half-chair conformation. The Zn(II) complex anion has a distorted tetra-hedral geometry. In the crystal, inter-molecular N-H?O, N-H?Cl, O-H?O, O-H?Cl and C-H?O hydrogen bonds link the components into a three-dimensional network. A ?-? inter-action with a centroid-centroid distance of 3.542?(14)?Å is also observed.
Project description:The structure of the title salt, (C(6)H(8)N)(2)[CuCl(3.4)Br(0.6)], consists of two 3-methyl-pyridinium cations and a distorted tetra-hedral [CuCl(3.4)Br(0.6)](2-) dianion. Substitutional disorder with Br is exhibited for three of the Cl atoms of the anion, giving a mixed chloride/bromide cuprate(II) anion. In the crystal, inter-molecular N-H?Cl hydrogen bonds link two cations to one anion, forming a three-ion aggregate. These are connected into a supra-molecular chain along the b axis via ?-? inter-actions between the pyridinium rings [centroid-centroid distance = 3.743?(3)?Å].
Project description:The title compound, (C(6)H(9)N(2))(2)[CuCl(4)], contains a distorted tetra-hedral [CuCl(4)](2-) anion and two protonated amino-pyridinium cations. The geometries of the protonated amino-pyridinium cations reveal amine-imine tautomerism. The crystal packing is influenced by N-H?Cl and C-H?Cl hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.635?(4) and 3.642?(4)°].
Project description:In the title compound, (C(19)H(18)NO(2))(2)[ZnI(4)]·CH(3)OH, each cation is nearly planar and exists in an E configuration, the dihedral angles between the quinolinium systems and the benzene rings being 1.78?(10) and 5.44?(10)° for the two cations. The [ZnI(4)](2-) anion displays a very slightly distorted tetra-hedral geometry. There are intra-molecular O-H?O hydrogen bonds between the hydr-oxy and meth-oxy groups in each cation which generate S(5) ring motifs. In the crystal structure, cations are linked together by O-H?O hydrogen bonds and weak C-H?O inter-actions, whereas the anions are linked to the cations through weak C-H?I inter-actions. The asymmetric unit also contains a methanol solvent mol-ecule which is linked to one of the cations by an O-H?O hydrogen bond and the anion through an O-H?I hydrogen bond. The crystal is further stabilized by C-H?? and ?-? inter-actions [centroid-centroid distances 3.6054?(15) and 3.6057?(15)?Å].
Project description:The structure of the title salt, (C8H10NO)2[HgCl4], is isotypic with that of the cuprate(II) and cobaltate(II) analogues. The asymmetric unit contains one 4-acetyl-anilinium cation and one half of a tetra-chlorido-mercurate(II) anion (point group symmetry m). The Hg-Cl distances are in the range 2.4308?(7)-2.5244?(11)?Å and the Cl-Hg-Cl angles in the range of 104.66?(2)-122.94?(4)°, indicating a considerable distortion of the tetra-hedral anion. In the crystal, cations are linked by an inter-molecular N-H?O hydrogen-bonding inter-action, leading to a C(8) chain motif with the chains extending parallel to the b axis. There is also a ?-? stacking inter-action with a centroid-to-centroid distance of 3.735?(2)?Å between neighbouring benzene rings along this direction. The anions lie between the chains and inter-act with the cations through inter-molecular N-H?Cl hydrogen bonds, leading to the formation of a three-dimensional network structure.
Project description:In the title mol-ecular salt, (C5H8N3)2[CoCl4], the cations are protonated at their pyridine N atoms and the anion is an almost regular tetra-hedron. The crystal structure consists of alternating inorganic layers, built from tetra-chlorido-cobaltate anions, and organic layers formed by protonated cations of 2,6-di-amino-pyridinium. The crystal packing is governed by C/N-H?Cl hydrogen-bonding inter-actions between the organic and the inorganic ions and Cl?Cl inter-actions. Moreover, the cations show a ?-? stacking inter-action [inter-centroid distance = 3.763?(2)?Å]. The prevalence of these inter-actions is illustrated by an analysis of the three-dimensional Hirshfeld surface and by two-dimensional fingerprint plots.
Project description:The asymmetric unit of the title compound, (C(7)H(7)N(2)S)(2)[ZnCl(4)], contains a network of 2-amino-benzothia-zolium cations and tetra-hedral [ZnCl(4)](2-) anions. The crystal packing is influenced by cation-to-anion N-H?Cl and C-H?Cl hydrogen bonds. The [ZnCl(4)](2-) anions have a distorded tetra-hedral geometry. Inter-molecular ?-? stacking inter-actions are present between neighboring benzene rings, thia-zole and benzene rings and neighboring thia-zole rings [centroid-centroid distances = 3.711?(2), 3.554?(1), 3.536?(2) and 3.572?(1)?Å].
Project description:The title compound, (C(6)H(8)N)(2)[CuCl(4)], is composed of two 3-methyl-pyridinium cation and one tetra-chloridocuprate(II) anion. The geometry around the copper(II) ion is that of a distorted tetra-hedron. In the crystal structure, the anions and cations are linked by three different N-H?Cl hydrogen bonds. In addition, the crystal structure exhibits aromatic ?-? inter-actions between the pyridinium rings of two discrete units [centroid-centroid distance = 3.704?(2)?Å].
