2,3,5-Triphenyl-pyrazine.

ABSTRACT: In the title mol-ecule, C(22)H(16)N(2), the pyrazine ring deviates very slightly from planarity [maximum deviation 0.044?(3)?Å], tending towards a twist-boat conformation. The phenyl ring at position 3 makes dihedral angles of 64.0?(2) and 45.8?(2)°, respectively, with the phenyl rings at positions 2 and 5. The dihedral angle between the phenyl rings at positions 2 and 5 is 49.7?(2)°. A C-H?? inter-action is found in the crystal structure, but no classical hydrogen bonds form.

In the title mol-ecule, C(22)H(16)N(2), the pyrazine ring deviates very slightly from planarity [maximum deviation 0.044 (3) Å], tending towards a twist-boat conformation. The phenyl ring at position 3 makes dihedral angles of 64.0 (2) and 45.8 (2)°, respectively, with the phenyl rings at positions 2 and 5. The dihedral angle between the phenyl rings at positions 2 and 5 is 49.7 (2)°. A C-H⋯π inter-action is found in the crystal structure, but no classical hydrogen bonds form. ...[more]

2,3,5-Triphenyl-2H-tetra-zol-3-ium iodide.

Project description:The asymmetric unit of the title mol-ecular salt, C(19)H(15)N(4) (+)·I(-), contains four 2,3,5-triphenyl-2H-tetra-zol-3-ium cations and five iodide anions, with two of the latter lying on crystallographic inversion centres. In each cation, the tetra-zole ring is essentially planar (r.m.s. deviations = 0.004-0.007?Å).

2-Ethyl-3,5,6-triphenyl-pyrazine.

Project description:In the title mol-ecule, C(24)H(20)N(2), the pyrazine ring is significantly distorted from planarity, presumably due to steric crowding, and its conformation is well described as a flattened twist-boat. The benzene ring adjacent to the ethyl group forms dihedral angles of 53.79?(13) and 85.47?(12)° with the other benzene rings; the dihedral angle between adjacent benzene rings is 57.90?(12)°. The ethyl group is disordered over two positions; the site-occupancy factor of the major component is 0.546?(4). No hydrogen bonds are found in the crystal structure.

Bis(2,3,5-triphenyl-tetra-zolium) tetra-thio-cyanato-cobaltate(II).

Project description:The title compound, (C(19)H(15)N(4))(2)[Co(NCS)(4)], has two crystallographycally different molecules of bis-(2,3,5-triphenyl-tetra-zolium) tetra-thio-cyanatecobaltate in the asymmetric unit. There are only minor geometric differences between them. Each cobalt(II) ion is coordinated by the N atoms of four NCS anions, showing the magnitude of the magnetic moment expected from the NCS(-) crystal field strength.

Project description:The mol-ecule of the title compound, C(9)H(12)O(2), is approximately planar (mean atomic deviation = 0.0346?Å) and disposed about a crystallographic centre of symmetry.

2-Amino-4,6-dimethyl-pyrimidin-1-ium 2,3,5-triiodo-benzoate 2,3,5-triiodo-benzoic acid monosolvate.

Project description:In the crystal structure of the title compound, C(6)H(10)N(3) (+)·C(7)H(2)I(3)O(2) (-)·C(7)H(3)I(3)O(2), two R(2) (2)(8) motifs are observed. One is generated by the inter-action of the 2-amino-4,6-dimethyl-pyrimidin-1-ium cation with the carboxyl-ate group of the 2,3,5-triiodo-benzoate anion via N-H?O hydrogen bonds. The other R(2) (2)(8) motif is formed by the inter-action of two centrosymmentrically related pyrimidine moieties through N-H?N hydrogen bonds. The two motifs combine to form a linear heterotetra-meric unit. Heterotetra-meric units are linked by a carbox-yl-carboxyl-ate O-H?O hydrogen bond (involving the O-H group of neutral 2,3,5-triiodo-benzoic acid and an O atom of the anion), forming a supra-molecular chain along the a axis. In addition, components are held by weak I?O interactions in the range 3.023?(5) to 3.382?(5)?Å and I?I inter-actions in the range 3.6327?(7) to 4.0025?(8)?Å.
