Bis[bis-(2-ethyl-5-methyl-1H-imidazol-4-yl-?N)methane](nitrato-?O,O')nickel(II) nitrate.

ABSTRACT: 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).

Project description: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.

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 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.

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