Crystal structure of 2-methyl-1H-imidazol-3-ium hydrogen oxalate dihydrate.

ABSTRACT: Single crystals of the title mol-ecular salt, C4H7N2 (+)·HC2O4 (-)·2H2O, were isolated from the reaction of 2-methyl-1H-imidazole and oxalic acid in a 1:1 molar ratio in water. In the crystal, the cations and anions are positioned alternately along an infinite [010] ribbon and linked together through bifurcated N-H?(O,O) hydrogen bonds. The water mol-ecules of crystallization link the chains into (10-1) bilayers, with the methyl groups of the cations organized in an isotactic manner.

Crystal structure of 1-(1-methyl-1H-imidazol-2-yl)-4-phenyl-1H-1,2,3-triazole dihydrate.

Project description:The title compound, C12H11N5·2H2O, which crystallizes as a dihydrate, was obtained by Cu(I)-catalysed azide-alkyne cyclo-addition from 2-azido-1-methyl-imidazole and phenyl-ethyne. The dihedral angles between the central triazole ring (r.m.s. deviation = 0.004 Å) and the pendant imidazole (r.m.s. deviation = 0.006 Å) and phenyl rings are 12.3 (2) and 2.54 (19)°, respectively. In the crystal, the water mol-ecules are connected into [010] chains by O-H⋯O hydrogen bonds, while O-H⋯N hydrogen bonds connect the water mol-ecules to the organic mol-ecules, generating corrugated (100) sheets.

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 structures of the two salts 2-methyl-1H-imidazol-3-ium nitrate-2-methyl-1H-imidazole (1/1) and 2-methyl-1H-imidazol-3-ium nitrate.

Project description:The title salts, C4H7N2 (+)·NO3 (-)·C4H6N2, (I), and C4H7N2 (+)·NO3 (-), (II), were obtained from solutions containing 2-methyl-imidazole and nitric acid in different concentrations. In the crystal structure of salt (I), one of the -NH H atoms of the imidazole ring shows half-occupancy, hence only every second mol-ecule is in its cationic form. The nitrate anion in this structure lies on a twofold rotation axis. The neutral 2-methyl-imidazole mol-ecule and the 2-methyl-1H-imidazol-3-ium cation inter-act through N-H⋯N hydrogen bonds to form [(C4H6N2)⋯(C4H7N2)(+)] pairs. These pairs are linked with two nitrate anions on both sides through bifurcated N-H⋯(O,O) hydrogen bonds into chains running parallel to [001]. In the crystal structure of salt (II), the C4H7N2 (+) cation and the NO3 (-) anion are both located on a mirror plane, leading to a statistical disorder of the methyl H atoms. The cations and anions again inter-act through bifurcated N-H⋯(O,O) hydrogen bonds, giving rise to the formation of chains consisting of alternating anions and cations parallel to [100].

Project description:In the title compound, C(3)H(5)N(2) (+)·C(2)HO(4) (-), the anions form centrosymmetric dimers through cyclic O-H?O hydrogen-bonding associations [graph set R(2) (2)(10)]. These dimers are then linked through a cyclic R(4) (2)(10) N-H?O hydrogen-bonding association involving two cations and the carboxyl O-atom acceptors of separate anions, giving chain structures extending across the (111) plane.

Hydrogen-bonded network in the salt 4-methyl-1H-imidazol-3-ium picrate.

Project description:In the title molecular salt, C4H7N2 (+)·C6H2N3O7 (-), the phenolic proton of the starting picric acid has been transferred to the imidazole N atom. The nitro groups are twisted away from the benzene ring plane, making dihedral angles of 12.8 (2), 9.2 (4) and 29.3 (2)°. In the crystal, the component ions are linked into chains along [010] via N-H⋯O and bifurcated N-H⋯(O,O) hydrogen bonds. These chains are further linked by weak C-H⋯O hydrogen bonds into a three-dimensional network. The complex three-dimensional network can be topologically simplified into a 4-connected uninodal net with the point symbol {4.8(5)}.

Crystal structure of 2-methyl-1H-imidazol-3-ium aqua-tri-chlorido-(oxalato-?(2) O,O')stannate(IV).

Project description:The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octa-hedral coordination environment defined by three chlorido ligands, an oxygen atom from a water mol-ecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N-H?O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex [Sn(H2O)Cl3(C2O4)](-) anion. Neighbouring stannate(IV) anions are linked through O-H?O hydrogen bonds involving the water mol-ecule and the two non-coordinating oxalate oxygen atoms. In combination with additional N-H?Cl hydrogen bonds between cations and anions, a three-dimensional network is spanned.

These clusters are inter-connected via anions through N-H⋯O hydrogen bonds, building a three-dimensional network.

Crystal structure of di-chlorido-bis-(1,3,4,5-tetra-methyl-1H-imidazol-2-ium-2-thiol-ate-κS)nickel(II).

Project description:In the mol-ecular structure of the title compound, [NiCl2(C7H12N2S)2], the Ni(II) atom has a distorted tetra-hedral geometry, coordinated by two Cl atoms [Ni-Cl= 2.2336 (6) Å] and two thione S atoms [Ni-S= 2.3024 (6) Å]. The angles at the Ni(II) cation, which lies on a twofold rotation axis, are Cl-Ni-Cl = 115.58 (3)° and S-Ni-S = 94.55 (3)°. All other angles at the central Ni(II) atom range from 109.46 (2) to 112.96 (2)°. The C-S-Ni angle is 99.91 (6)°. The planes of two imidazolium rings make a dihedral angle of 70.56 (6)°.
