Crystal structure of [{FeCl₃}₂(μ-PC^HP)₂] [PC^HP = 1,3-bis-(2-di-phenyl-phosphanyleth-yl)-3H-imidazol-1-ium] with an unknown solvent.

ABSTRACT: The crystal structure of the title compound, bis-{μ-1,3-bis-[2-(di-phenyl-phosphan-yl)eth-yl]-1H-imidazole-κ² P:P'}bis-[tri-chlorido-iron(III)], [Fe₂Cl₆(C₃₁H₃₁N₂P₂)₂] or [{FeCl₃}₂(μ-PC^HP)₂] (PC^HP = C₃₁H₃₁N₂P₂), consists of dinuclear complexes that are located about centres of inversion. The Fe^III cation is in a distorted trigonal-bipyramidal coordination with three chloride ligands located in the trigonal plane and two P atoms of symmetry-related PC^HP ligands occupying the axial positions. Within the centrosymmetric complex, a pair of intra-molecular C-H⋯Cl hydrogen bonds between aromatic CH groups and chloride ligands are found. Individual complexes are linked into layers parallel to (01) by inter-molecular C-H⋯Cl hydrogen bonds. No pronounced inter-molecular inter-actions occur between these layers. This arrangement leaves space for disordered solvent mol-ecules. Electron density associated with these additional solvent mol-ecules was removed with the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18]. The given chemical formula and other crystal data do not take into account the unknown solvent mol-ecule(s).

1,3-Diprop-2-ynyl-1H-imidazol-3-ium bromide.

Project description:In the title salt, C(9)H(9)N(2) (+)·Br(-), the ethynyl groups are nearly anti-parallel to each other [the angle between the two ethynyl groups is179.7 (2)°]. No classical hydrogen bonds or π-π inter-actions are observed. The mol-ecules are linked by C-H⋯Br hydrogen bonds. The bromide anions are involved in inter-actions with three H atoms.

2-Bromo-1,3-diisopropyl-4,5-dimethyl-1H-imidazol-3-ium dicyanidoargentate.

Project description:The title structure, (C(11)H(20)BrN(2))[Ag(CN)(2))], is built up from an approximately C(2v)-symmetric imidazolium cation and a nearly linear dicyanidoargentate anion [N-Ag-N = 176.6?(9)° and Ag-C-N = 178.8?(9) and 177.2?(11)°]. These two constituents are linked by a remarkably short inter-action between the Br atom of the imidazolium cation [C-Br = 1.85?(3)?Å] and one N atom of the cyanidoargentate anion [Br?N = 2.96?(2)?Å], which is much less than the sum of the van der Waals radii (3.40?Å). The crystal studied was twinned by merohedry.

2-Hy-droxy-methyl-1,3-dimethyl-1H-imidazol-3-ium triiodide.

Project description:The crystal packing of the title salt, C6H11N2O(+)·I3 (-), can be described as consisting of alternating layers of cations and anions parallel to the (100) plane along the a-axis direction. The components are linked by O-H⋯I, C-H⋯I and C-H⋯O interactions, generating a three-dimensional network. The O atom deviates from the imidazol ring by 0.896 (2) Å.

Project description:In the cation of the title salt, C(19)H(19)N(4)O(2) (+)·Cl(-), the dihedral angles between the imidazole ring and the phenyl rings are 70.39 (8) and 86.26 (9)°. The chloride anion inter-acts with the cation through an N-H⋯Cl hydrogen bond. In the crystal, classical N-H⋯O hydrogen bonds link the cations into chains parallel to the b axis. Non-classical C-H⋯Cl and C-H⋯O hydrogen bonds further connect the chains into a three-dimensional network.

catena-Poly[2-methyl-1H-imidazol-3-ium [(aqua-chloridocadmate)-di-μ-chlorido]].

Project description:The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, with a distorted octa-hedral geometry, is coordinated by five Cl(-) ions and one water mol-ecule. Intra-chain O-H⋯Cl hydrogen bonding and N-H⋯Cl hydrogen bonding between the cations and the anionic chains consolidate the crystal packing.

Crystal structure of 1H-imidazol-3-ium 2-(1,3-dioxoisoindolin-2-yl)acetate.

Project description:The title salt, C3H5N2 (+)·C10H6NO4 (-), was obtained during a study of the co-crystallization of N'-[bis-(1H-imidazol-1-yl)methyl-ene]isonicotinohydrazide with (1,3-dioxoisoindolin-2-yl)acetic acid under aqueous conditions. The 1,3-dioxoisoindolinyl ring system of the anion is essentially planar [maximum deviation = 0.023 (2) Å]. In the crystal, cations and anions are linked via classical N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds, forming a three-dimensional network. Weak C-H⋯π inter-actions and π-π stacking inter-actions [centroid-centroid distances = 3.4728 (13) and 3.7339 (13) Å] also occur in the crystal.
