Aqua-[bis-(2-ethyl-5-methyl-1H-imidazol-4-yl-?N)methane]-oxalatocopper(II) dihydrate.

ABSTRACT: In the title compound, [Cu(C(2)O(4))(C(13)H(20)N(4))(H(2)O)]·2H(2)O, the Cu(II) atom exhibits a distorted square-pyramidal geometry with the two N atoms of the imidazole ligand and the two O atoms of the oxalate ligand forming the basal plane, while the O atom of the coordinated water mol-ecule is in an apical position. The Cu(II) atom is shifted 0.232?(2)?Å out of the basal plane toward the water mol-ecule. The asymmetric unit is completed by two solvent water mol-ecules. These water mol-ecules participate in the formation of an intricate three-dimensionnal network of hydrogen bonds involving the coordinated water mol-ecule and the NH groups.

Project description:In the title compound, [Ni(NO(3))(C(13)H(20)N(4))(2)]NO(3), the Ni(II) ion shows a distorted octa-hedral geometry formed by four N atoms from two bis-(2-ethyl-5-methyl-1H-imidazol-4-yl)methane ligands and two O atoms from a chelating nitrate anion. Three ethyl groups in the complex cation and the O atoms of the uncoordinated nitrate anion are disordered over two sets of positions [occupancy ratios of 0.52 (3):0.48 (3) and 0.63 (3):0.37 (3), respectively]. In the crystal, inter-molecular N-H⋯O hydrogen bonds connect the complex cations into a zigzag chain along [010] and further N-H⋯O hydrogen bonds between the chains and the uncoordinated nitrate anions lead to layers parallel to (100).

2-(2-Methyl-5-nitro-1H-imidazol-1-yl)ethyl methane-sulfonate.

Project description:The asymmetric unit of the title compound, C(7)H(11)N(3)O(5)S, contains two independent mol-ecules with virtually identical conformations. The imidazole rings of both mol-ecules are essentially planar (r.m.s. deviations = 0.0019 and 0.0038 Å), with a dihedral angle 9.25 (19)° between them. The nitro groups are oriented at 4.5 (2) and 6.44 (13)° with respect to the imidazole rings. In the crystal, mol-ecules are linked to form a three-dimensional framework by C-H⋯O and C-H⋯N hydrogen bonds.

Bis[μ-1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene-κN:N]silver(I) dinitrate dihydrate.

Project description:The reaction of 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) with silver(I) nitrate in a 1:1 molar ratio generates the metallacyclic title complex, [Ag(2)(C(12)H(14)N(4))(2)](NO(3))(2)·2H(2)O, in which the bib ligand displays a cis configuration. Each bib ligand acts as a bidentate bridging ligand connecting a pair of Ag(I) ions to form a [2 + 2] metallamacrocycle in which the Ag⋯Ag distance is 6.77 (2) Å. Each Ag(I) ion has weak contacts (2.91 Å) with the nitrate anion. The uncoordinated water mol-ecules make hydrogen bonds with nitrate O atoms, forming chains. The H atoms attached to the uncoordinated nitro-gen inter-act with these chains through N-H⋯O hydrogen bonds, forming layers parallel to the (11) plane.

Project description:In the crystal structure of the title complex, [CuCl(C17H24N8)]ClO4, the copper(II) metal exhibits an N4Cl penta-coordinate environment in a distorted square-pyramidal geometry. Coordination to the metal centre occurs through the three 1-methyl-imidazole N atoms from the pendant groups, one amine N atom from the imidazolidine moiety and one chlorido anion. Inter-molecular inter-actions take place at two of the 1-methyl--imidazole rings in the form of parallel-displaced π-π stacking inter-actions forming chains parallel to the a axis. Three O atoms of the perchlorate anion are rotationally disordered between two orientations with occupancies of 0.5.

The bis-(tetra-zolyl)ethene ligand is planar within 0.0366 (7) Å. All 'active' H atoms participate in hydrogen bonds, which link mol-ecules of the complex and the uncoordinated water mol-ecules into an infinite three-dimensional framework.

The imidazole rings of Me(2)BIM form intra-molecular ?-? stacking inter-actions [centroid-centroid distances = 3.445?(2) and 3.547?(2)?Å].
