Crystal structure of bis-(1-ethyl-pyridinium) dioxonium hexa-cyanidoferrate(II).

ABSTRACT: The title compound, (C₇H₁₀N)₂(H₃O)₂[Fe(CN)₆] or (Etpy)₂(H₃O)₂[Fe(CN)₆] (Etpy⁺ is 1-ethyl-pyridinium), crystallizes in the space group Pnnm. The Fe^II atom of the [Fe(CN)₆]^4- anion lies on a site with site symmetry ..2/m, and has an octa-hedral coordination sphere defined by six cyanido ligands. Both the Etpy⁺ and the oxonium cations are located on a mirror plane. In the crystal, electron-donor anions of [Fe(CN)₆]^4- and electron-acceptor cations of Etpy⁺ are each stacked parallel to the b axis, resulting in a columnar structure with segregated moieties. The crystal packing is stabilized by a three-dimensional O-H?N hydrogen-bonding network between the oxonium ions and the cyanide ligands of [Fe(CN)₆]^4-.

Crystal structure of dicaesium strontium hexa-cyanidoferrate(II), Cs2Sr[Fe(CN)6], from laboratory X-ray powder data.

Project description:Ferrocyanides with general formula A I xB II y [Fe(CN)6], where A and B are cations, are thought to accept many substitutions on the A and B positions. In this communication, the synthesis and crystal structure of Cs2Sr[Fe(CN)6] are reported. The latter was obtained from K2Ba[Fe(CN)6] particles, put in contact with caesium and strontium ions. Hence, a simultaneous ion-exchange mechanism (Cs for K, Sr for Ba) occurs to yield Cs2Sr[Fe(CN)6]. The synthesis protocol shows that K2BaFe(CN)6 particles can be used for the simultaneous trapping of radioactive caesium and strontium nuclides in water streams. Cs2Sr[Fe(CN)6] adopts the cryolite structure type and is isotypic with the known compound Cs2Na[Mn(CN)6] [dicaesium sodium hexa-cyanidomanganate(III)]. The octa-hedrally coordinated Sr and Fe sites both are located on inversion centres, and the eightfold-coordinated Cs site on a general position.

Synthesis, crystal structure and Hirshfeld surface of bis-(2-amino-pyridinium) hexa-chlorido-stannate(IV).

Project description:In the title mol-ecular salt, (C5H7N2)2[SnCl6], the cation is protonated at the pyridine N atom and the complete dianion is generated by a crystallographic centre of symmetry. In the crystal, N-H?Cl hydrogen bonds link the components into a three-dimensional network built up from the stacking of alternate cationic and anionic layers. The nature of the inter-molecular inter-actions has been analysed in terms of the Hirshfeld surfaces of the cations and the anions. The thermal behaviour and the Raman spectrum of the title compound are reported.

Crystal structure of bis-(di-methyl-ammonium) hexa-aqua-cobalt(II) bis-(sulfate) dihydrate.

Project description:The title salt, (C2H8N)2[Co(H2O)6)](SO4)2·2H2O, is isotypic with (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O. The Co-O bond lengths in the [Co(H2O)6](2+) complex cation show very similar distances as in the related Tutton salt (NH4)2[Co(H2O)6)](SO4)2 [average 2.093?(17)?Å], but are significantly longer than in the isotypic Ni(II) compound (?d ? 0.04?Å). The cobalt cation reaches an overall bond-valence sum of 1.97 valence units. The S-O distances are nearly equal, ranging from 1.454?(4) to 1.470?(3)?Å [mean 1.465?(12)?Å]; however, the O-S-O angles vary clearly from 108.1?(2) to 110.2?(2)° [average bond angle 109.5?(9)°]. The non-coordinating water mol-ecules and di-methyl-ammonium cations connect the sulfate tetrahedra and the [Co(H2O)6](2+) octa-hedron via O-H?O and N-H?O hydrogen bonds of weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel to (001).

Crystal structure of bis-(2-amino-5-chloro-pyridinium) tetra-chlorido-cobaltate(II).

Project description:The title salt, (C5H6ClN2)2[CoCl4], was synthesized by slow evaporation of an aqueous solution at room temperature. The asymmetric unit consists of two essentially planar (C5H6ClN2)(+) cations [maximum deviations = 0.010?(3) and 0.014?(3)?Å] that are nearly perpendicular to each other [dihedral angle = 84.12?(7)°]. They are bonded through N-H?Cl hydrogen bonds to distorted [CoCl4](2-) tetra-hedra, leading to the formation of undulating layers parallel to (100). The structure is isotypic with the Zn analogue [Kefi et. al (2011). Acta Cryst. E67, m355-m356.].

Bis[N-(1-naphth-yl)ethyl-enediammonium] hexa-bromidoplumbate(II).

Project description:The title compound, (C(12)H(16)N(2))(2)[PbBr(6)], is an organic-inorganic salt, with two doubly protonated N-(1-naphth-yl)ethyl-enediammonium cations and one octa-hedral hexa-bromidoplumbate(II) anion. The Pb(II) atom is located on a centre of inversion. The crystal structure consists of alternating inorganic and organic layers parallel to the bc plane. Face-to-face aromatic stacking inter-actions [centroid-centroid distance = 3.505 (5) Å] occur between parallel naphthalene systems in the organic layers, and N-H⋯Br hydrogen bonds between the cations and anions stabilize the crystal structure.

Bis(4-amino-pyridinium) hexa-aqua-nickel(II) bis-(sulfate).

Project description:In the title compound, (C5H7N2)2[Ni(H2O)6](SO4)2, the Ni(II) cation is located on an inversion centre and is coordinated by six aqua ligands in a slightly distorted octa-hedral coordination environment. The [Ni(H2O)6](2+) ions are connected through an extensive network of O-H?O hydrogen bonds to sulfate anions, leading to the formation of layers parallel to (001). The 4-amino-pyridinium cations are located between these layers and are connected to the anionic framework by N-H?O hydrogen bonds. Weak ?-? inter-actions between the pyridine rings, with a centroid-centroid distance of 3.754?(9)?Å, provide additional stability to the crystal packing.

Crystal structure of bis-(1-hexyl-N,N-di-methyl-pyridinium) bis-(maleo-nitrile-dithiol-ato)nickelate(II).

Project description:The asymmetric unit of the title compound, (C13H23N2)2[Ni(C4N2S2)2], consists of a 1-hexyl-N,N-di-methyl-pyridinium cation and one half of a [Ni(mnt)2](2-) dianion (mnt(2-) = maleo-nitrile-dithiol-ate) in which the Ni(2+) cation lies on a crystallographic inversion centre. The square-planar coordination about Ni(2+) comprises four S atoms from two bidentate chelate mnt(2-) ligands [Ni-S = 2.1791?(9) and 2.1810?(8)?Å, and S-Ni-S bite angle = 91.93?(3)°]. The hydro-carbon chains of cations show trans-planar conformations and lie approximately parallel to the long mol-ecular axis of the [Ni(mnt)2](2-) anions, giving stacks along the c axis. The anions and cations form layers lying parallel to the bc plane. Only weak C-H?Ni and C-H?? associations are present in the crystal packing.

2-(2-Ammonio-ethyl)pyridinium hexa-chloridorhenate(IV).

Project description:In the title anti-ferromagnetic material, (C(7)H(12)N(2))[ReCl(6)], the Néel temperature is observed at 5?K. The salt is stabilized by an extensive network of N-H?Cl and C-H?Cl hydrogen bonds, where hydrogen-bonded anion chains and characteristic cation-anion motifs are present. Similar systems play an important role in crystal engineering as hydrogen bonds that can transmit magnetic inter-actions.

Crystal structure of hexa-kis-(dimethyl sulfoxide-?O)cobalt(II) bis-[tri-chlorido-(quinoline-?N)cobaltate(II)].

Project description:There are few reports that describe crystal structures of compounds containing cobalt complexed to either dimethyl sulfoxide (Me2SO) or quinoline (C9H7N). The title compound, [Co(C2H6OS)6][CoCl3(C9H7N)]2, is a cobalt salt in which the metal ion is complexed to both Me2SO and quinoline. In particular, we observed that anhydrous cobalt(II) chloride reacts with quinoline in Me2SO to form a salt that is to be formulated as [CoII(Me2SO)6]2+{[CoIICl3quinoline]2-}. The CoII atom in the cation portion of this mol-ecule lies on a inversion center and is bound to the O atoms of six Me2SO moieties in an octa-hedral configuration, while the CoII atom in the anion is attached to three chloride ligands and one quinoline moiety in a tetra-hedral arrangement.

Bis(2,4,6-trimethyl-pyridinium) hexa-chloridoplatinate(IV).

Project description:The asymmetric unit of the title compound, (C(8)H(12)N)(2)[PtCl(6)], contains one independent protonated 2,4,6-trimethyl-pyridinium cation and one half of a centrosymmetric [PtCl(6)](2-) anion. The Pt ion has an almost ideal octa-hedral coordination. In the crystal structure, intra-molecular N-H?Cl and inter-molecular C-H?Cl hydrogen bonds result in the formation of a supra-molecular structure.
