Crystal structure and Hirshfeld surface analysis of bis-[hydrazinium(1+)] hexa-fluorido-silicate: (N2H5)2SiF6.

ABSTRACT: In the title inorganic mol-ecular salt, (N2H5)2SiF6, the silicon atom at the centre of the slightly distorted SiF6 octa-hedron [range of Si-F distances = 1.6777?(4)-1.7101?(4)?Å] lies on a crystallographic inversion centre. In the crystal, the ions are connected by N-H?N and N-H?F hydrogen bonds; the former link the cations into [010] chains and the latter (some of which are bifurcated or trifurcated) link the ions into a three-dimensional network. The two-dimensional fingerprint plots show that F?H/H?F inter-actions dominate the Hirshfeld surface (75.5%) followed by H?H (13.6%) and N?H/H?N (8.4%) whereas F?F (1.9%) and F?N/N?F (0.6%) have negligible percentages. The title compound is isostructural with its germanium-containing analogue.

Crystal structure of bis-(9H-6-amino-purin-1-ium) hexa-fluorido-silicate(IV) dihydrate.

Project description:The asymmetric unit of the title compound, 2C5H6N5 (+)·SiF6 (2-)·2H2O, contains one adeninium cation, half of a hexa-fluorido-silicate anion located on an inversion centre and one lattice water mol-ecule. The adeninium cations are connected through N-H?N hydrogen bonds involving one H atom of the -NH2 group and the H atom of the protonated N atom of the adenine ring system, forming centrosymmetric ring motifs of the type R 2 (2)(10) and R 2 (2)(8), respectively. The overall connection of the cation leads to the formation of planar ribbons parallel to (122). In the ribbons, slipped ?-? stacking inter-actions, with a centroid-to-centroid distance of 3.6938?(9)?Å, an inter-planar distance of 3.455?Å and a slippage of 1.306?Å is observed. The hexa-fluorido-silicate anion and the water mol-ecule are linked through O-H?F hydrogen bonds [ring motif R 4 (4)(12)] into chains parallel to [100]. The cationic ribbons and anionic chains are finally connected through additional N-H?O, N-H?F and O-H?F hydrogen bonds into a three-dimensional network in which layers of adeninium cations and fluorido-silicate anions alternate parallel to (001).

Hydrazinium 2-amino-4-nitro-benzoate dihydrate: crystal structure and Hirshfeld surface analysis.

Project description:In the anion of the title salt hydrate, H5N2+·C7H5N2O4-·2H2O, the carboxyl-ate and nitro groups lie out of the plane of the benzene ring to which they are bound [dihedral angles = 18.80?(10) and 8.04?(9)°, respectively], and as these groups are conrotatory, the dihedral angle between them is 26.73?(15)°. An intra-molecular amino-N-H?O(carboxyl-ate) hydrogen bond is noted. The main feature of the crystal packing is the formation of a supra-molecular chain along the b axis, with a zigzag topology, sustained by charge-assisted water-O-H?O(carboxyl-ate) hydrogen bonds and comprising alternating twelve-membered {?OCO?HOH}2 and eight-membered {?O?HOH}2 synthons. Each ammonium-N-H atom forms a charge-assisted hydrogen bond to a water mol-ecule and, in addition, one of these forms a hydrogen bond with a nitro-O atom. The amine-N-H atoms form hydrogen bonds to carboxyl-ate-O and water-O atoms, and the amine N atom accepts a hydrogen bond from an amino-H atom. The hydrogen bonds lead to a three-dimensional architecture. An analysis of the Hirshfeld surface highlights the major contribution of O?H/H?O hydrogen bonding to the overall surface, i.e. 46.8%, compared with H?H contacts (32.4%).

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-(propane-1,3-diaminium) hexa-fluorido-aluminate di-aqua-tetra-fluorido-aluminate tetra-hydrate.

Project description:The title compound, (C3H12N2)2[AlF6][AlF4(H2O)2]·4H2O, was obtained by a solvothermal method in ethanol as solvent and with aluminium hydroxide, HF and 1,3-di-amino-propane as educts. The asymmetric unit contains a quarter each of two crystallographically independent propane-1,3-di-ammonium dicat-ions, [AlF6](3-) and [AlF4(H2O)2](-) anions and four water mol-ecules. The cations, anions and three of the independent water mol-ecules are situated on special positions mm, while the fourth water mol-ecule is disordered about a mirror plane. In the crystal, inter-molecular N-H?F and O-H?F hydrogen bonds link the cations and anions into a three-dimensional framework with the voids filled by water mol-ecules, which generate O-H?O hydrogen bonds and further consolidate the packing.

Crystal structure of bis-(propane-1,3-di-ammonium) hexa-fluorido-aluminate fluoride trihydrate.

Project description:The title compound, (C3H10N2)2[AlF6]F·3H2O, was obtained using the solvothermal method with aluminium hydroxide, HF and propane-1,3-di-amine as precursors in ethanol as solvent. The structure consists of isolated [AlF6](3-) octa-hedra, diprotonated propane-1,3-di-amine cations [(H2dap)(2+)], free fluoride ions and water mol-ecules of solvation. The Al-F bond lengths in the octa-hedral [AlF6](3-) anions range from 1.7690 (19) to 1.8130 (19) Å, with an average value of 1.794 Å. Each [AlF6](3-) anion is surrounded by three water mol-ecules and by six diprotonated amine cations. The 'free' fluoride ion is hydrogen bonded to four H atoms belonging to four dications and has a distorted tetra-hedral geometry. The three water mol-ecules are connected by hydrogen bonds, forming trimers that connect the AlF6 octa-hedra and dications into a three-dimensional framework.

Synthesis, crystal structure and Hirshfeld surface analysis of bis-(caffeinium) hexa-chlorido-platinum(IV) in comparison with some related compounds.

Project description:The mol-ecular and crystal structure of the title compound, (C8H11N4O2)2[PtCl6], synthesized from hexa-chloro-platinic acid and caffeine in methanol, was studied by single-crystal X-ray diffraction. The caffeinium cations form a double layer via hydrogen bonds and π-stacking inter-actions. The Hirshfeld surface analysis showed that the largest contribution to the crystal packing is made by H⋯H (31.2%), H⋯Cl/Cl⋯H (22.6%), O⋯H/H⋯O (21.9%) contacts for the cation and H⋯Cl/Cl⋯H (79.3%) contacts for the anion.

Bis(mefloquinium) butane-dioate ethanol monosolvate: crystal structure and Hirshfeld surface analysis.

Project description:The asymmetric unit of the centrosymmetric title salt solvate, 2C17H17F6N2O+· C4H4O4 2-·CH3CH2OH, (systematic name: 2-{[2,8-bis-(tri-fluoro-meth-yl)quinolin-4-yl](hy-droxy)meth-yl}piperidin-1-ium butane-dioate ethanol monosolvate) comprises two independent cations, with almost superimposable conformations and each approximating the shape of the letter L, a butane-dioate dianion with an all-trans conformation and an ethanol solvent mol-ecule. In the crystal, supra-molecular chains along the a-axis direction are sustained by charge-assisted hy-droxy-O-H⋯O(carboxyl-ate) and ammonium-N-H⋯O(carboxyl-ate) hydrogen bonds. These are connected into a layer via C-F⋯π(pyrid-yl) contacts and π-π stacking inter-actions between quinolinyl-C6 and -NC5 rings of the independent cations of the asymmetric unit [inter-centroid separations = 3.6784 (17) and 3.6866 (17) Å]. Layers stack along the c-axis direction with no directional inter-actions between them. The analysis of the calculated Hirshfeld surface reveals the significance of the fluorine atoms in surface contacts. Thus, by far the greatest contribution to the surface contacts, i.e. 41.2%, are of the type F⋯H/H⋯F and many of these occur in the inter-layer region. However, these contacts occur at separations beyond the sum of the van der Waals radii for these atoms. It is noted that H⋯H contacts contribute 29.8% to the overall surface, with smaller contributions from O⋯H/H⋯O (14.0%) and F⋯F (5.7%) contacts.

Crystal structure of μ-fluorido-bis-{(η(4)-cyclo-octa-diene)[hexa-fluorido-anti-monato(V)]platinum(II)} hexa-fluorido-anti-monate(V) hydrogen fluoride 0.75-solvate.

Project description:In the complex cation of the binuclear solvated title salt, [Pt2F(SbF6)2(C8H12)2]SbF6·0.75HF, an F atom bridges the two platinum(II) atoms with a bond angle of 123.3 (2)°. The corresponding Pt-F bond lengths are in the range of other fluorine-bridged binuclear platinum(II) complexes. Two of the three SbF6 (-) anions each coordinate with one F atom to one platinum(II) atom. Including the η(4)-bound cyclo-octa-diene (COD) ligands, the overall coordination sphere of each platinum(II) atom is square-planar. The third SbF6 (-) anion is not bound to the complex. Hydrogen fluoride is present in the crystal structure as a solvent disordered over three positions, each with an occupancy of 0.25. F⋯F distances of 2.5512 (7), 2.6076 (8) and 3.2215 (10) Å to surrounding SbF6 (-) anions are indicative of F-H⋯F hydrogen-bonding inter-actions although no H atoms could be localized for the disordered solvent mol-ecules. The resulting hydrogen-bonded network is three-dimensional.

Crystal structure and Hirshfeld surface analysis of 4,4'-(propane-1,3-diyl)bis(4H-1,2,4-triazol-1-ium) penta-fluorido-oxidovanadate(V).

Project description:In the structure of the title salt, (C7H12N6)[VOF5], second-order Jahn-Teller distortion of the coordination octa-hedra around V ions is reflected by coexistence of short V-O bonds [1.5767?(12)?Å] and trans-positioned long V-F bonds [2.0981?(9)?Å], with four equatorial V-F distances being inter-mediate in magnitude [1.7977?(9)-1.8913?(9)?Å]. Hydrogen bonding of the anions is restricted to F-atom acceptors only, with particularly strong N-H?F inter-actions [N?F = 2.5072?(15)?Å] established by axial and cis-positioned equatorial F atoms. Hirshfeld surface analysis indicates that the most important inter-actions are overwhelmingly H?F/F?H, accounting for 74.4 and 36.8% of the contacts for the individual anions and cations, respectively. Weak CH?F and CH?N bonds are essential for generation of three-dimensional structure.

Crystal structure and Hirshfeld surface analysis of hexa-kis-(?-benzoato-?2O:O')bis-(pyridine-3-carbo-nitrile-?N1)trizinc(II).

Project description:The asymmetric unit of the title complex, [Zn3(C7H5O2)6(C6H4N2)2], contains one half of the complex mol-ecule, i.e. one and a half ZnII cations, three benzoate (Bnz) and one pyridine-3-carbo-nitrile (Cpy) mol-ecule; the Bnz anions act as bidentate ligands through the carboxyl-ate O atoms, while the Cpy ligand acts as a monodentate N(pyridine)-bonding ligand. The complete centrosymmetric trinuclear complex thus comprises a linear array of three ZnII cations. The central ZnII cation shows an octa-hedral coordination and is bridged to each of the terminal ZnII cations by three Bnz anions. By additional coordination of the CPy ligand, the terminal ZnII cations adopt a trigonal-pyramidal coordination environment. In the crystal, the Bnz anions link to the Cpy N atoms via weak C-H?N hydrogen bonds, forming a two-dimensional network. C-H?? and ?-? inter-actions [between the benzene and pyridine rings of adjacent mol-ecules with an inter-centroid distance of 3.850?(4)?Å] help to consolidate a three-dimensional architecture. The Hirshfeld surface analysis confirms the role of H-atom contacts in establishing the packing.
