2-[3-(Pyridin-1-ium-2-yl)-1H-pyrazol-1-yl]-6-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]pyridinium sulfate methanol monosolvate.

ABSTRACT: The title solvated salt, C21H17N7 (2+)·SO4 (2-)·CH3OH, was obtained when we attempted to prepare the complex of ferrous sulfate and 2,6-bis-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]pyridine in methanol. The dihedral angles between adjacent pyridine and pyrazole rings range from 3.8?(1) to 13.4?(1)°. An intra-molecular N-H?N hydrogen bond occurs. In the crystal, N-H?O and O-H?N hydrogen bonds between solvent methanol mol-ecules and the cations generate zigzag chains along [110].

The title solvated salt, C21H17N7 (2+)·SO4 (2-)·CH3OH, was obtained when we attempted to prepare the complex of ferrous sulfate and 2,6-bis-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]pyridine in methanol. The dihedral angles between adjacent pyridine and pyrazole rings range from 3.8 (1) to 13.4 (1)°. An intra-molecular N-H⋯N hydrogen bond occurs. In the crystal, N-H⋯O and O-H⋯N hydrogen bonds between solvent methanol mol-ecules and the cations generate zigzag chains along [110]. ...[more]

Bromidobis[3-(1H-pyrazol-1-yl-?N(2))propionamide-?O]copper(II) bromide methanol monosolvate.

Project description:The title copper(II) N-pyrazolylpropanamide (PPA) complex, [CuBr(PPA)(2)]Br, was obtained in 78% yield by treatment of CuBr(2) with an excess of the ligand in methanol. Crystallization from the mother liquid afforded the title compound, i.e. the methanol solvate [CuBr(C(6)H(9)N(3)O)(2)]Br·CH(3)OH or [CuBr(PPA)(2)]Br·MeOH, as bright green crystals. In the solid state, the title salt comprises isolated [CuBr(PPA)(2)](+) cations, separated bromide ions and methanol of crystallization. In the cation, the central Cu(II) ion is coordinated by two N,O-chelating PPA ligands and one Br(-) ion. The coordination geometry around the Cu(II) ion is distorted trigonal-bipyramidal with the bromide ligand and the amide O atoms occupying the equatorial positions [Cu-Br = 2.4443?(4)?Å; Cu-O = 2.035?(2) and 2.179?(2)?Å], while the pyrazole N atoms coordinate in the axial positions [Cu-N = 1.975?(2) and 1.976?(2)?Å]. In the crystal, the three constituents are linked by N-H?Br, O-H?Br, and N-H?O hydrogen bonds, forming a three-dimensional network.

2-(Pyridin-2-yl-amino)-pyridinium thio-cyanate acetonitrile monosolvate.

Project description:The title compound, C(10)H(10)N(3) (+)·NCS(-)·CH(3)CN, is the acetonitrile solvate of the thio-cyanate salt of protonated dipyridin-2-yl-amine. Protonation occurs at one of the pyridine N atoms. The mol-ecular geometry around the central N atom is essentially planar (sum of angles = 359.89°). In the crystal, N-H?N hydrogen bonds, as well as C-H?S contacts link the different residues into chains along the c-axis direction. Inter-action between aromatic systems gives rise to ?-stacking, the shortest distance between two ?-systems being 3.6902?(6)?Å. Both the protonated and the non-protonated pyridyl groups are involved in the latter inter-action.

Project description:The asymmetric unit of the title compound, C(20)H(14)N(4)·CH(4)O, contains two independent half-mol-ecules, each located on an inversion centre, and a methanol solvent mol-ecule.

N, N-H?O and O-H?N hydrogen-bonding inter-actions between the benzimidazole units and methanol solvent mol-ecules. ?-? stacking inter-actions also occur between the benzimidazole rings of adjacent mol-ecules, with centroid-centroid distances of 3.720?(14)?Å and inter-planar distances of 3.53?(1)?Å .

Project description:In the title solvated salt, C8H12N9 (+)·ClO4 (-)·CH3OH, the dihedral angle between the tetra-zine and pyrazole rings is 26.05?(7)°. The two N atoms bonded to the 1,2,4,5-tetra-zine ring deviate from the plane defined by its four N atoms by 0.234?(2) and 0.186?(2)?Å. There is an intra-molecular N-H?N hydrogen bond between the protonated guanidine fragment and one of the tetra-zine N atoms. In the crystal, two cations and two perchlorate anions are connected via N-H?O hydrogen bonds into centrosymmetric assemblies. These assemblies are further linked into a two-dimensional network parallel to (100) via bifurcated O-H?(N,N) hydrogen bonds formed with the bridging methanol mol-ecules.

The crystal packing is further stabilized by F?? contacts involving the tetra-fluoridoborate anions and the five-membered rings [F?centroid = 2.811?(2)?Å].
