1,2,4,5-Tetra-fluoro-3,6-diiodo-benzene-4-(pyridin-4-ylsulfan-yl)pyridine (1/1).

ABSTRACT: The asymmetric unit of the title 1:1 adduct, C(10)H(8)N(2)S·C(6)F(4)I(2), comprises a half-mol-ecule of 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene, and half a 4-(pyridin-4-ylsulfan-yl)pyridine mol-ecule. The former is completed by crystallographic inversion symmetry, the latter by twofold symmetry, with the S atom lying on the rotation axis. The almost planar 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene mol-ecule (r.m.s. deviation of all 12 atoms = 0.016?Å) and twisted 4-(pyridin-4-ylsulfan-yl)pyridine mol-ecule [dihedral angle between pyridyl rings = 54.88?(13)°] are connected by N?I inter-actions [2.838?(4)?Å], generating a supra-molecular chain with a step-ladder topology. These chains are connected in the crystal by C-H?F and C-H??(pyrid-yl) inter-actions.

1,2,4,5-Tetra-fluoro-3,6-diiodo-benzene-2,3-bis-(pyridin-2-yl)pyrazine (1/1).

Project description:The components of the title 1:1 co-crystal, C(14)H(10)N(4)·C(6)F(4)I(2), are connected via an N?I [2.959?(4)?Å] halogen bond, in which the N atom is part of the relatively electron-rich pyrazine ring. The C(6)F(4)I(2) mol-ecule is almost planar [r.m.s. deviation = 0.038?Å] but there are significant twists in the pyrazine derivative, as seen in the dihedral angles [31.3?(2) and 54.6?(2)°] formed between the pendant pyridyl rings and the central pyrazine ring. The bimolecular aggregates are sustained in the crystal by C-H?F and ?-? inter-actions [ring centroid(pyrid-yl)-ring centroid(benzene) = 3.678?(3)?Å].

Cyclo-hexa-2,5-diene-1,4-dione-1,2,4,5-tetra-fluoro-3,6-diiodo-benzene (1/1).

Project description:The asymmetric unit of the title co-crystal adduct, C(6)H(4)O(2)·C(6)F(4)I(2), comprises a half-mol-ecule each of cyclo-hexa-2,5-diene-1,4-dione and 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene. The C(6)F(4)I(2) mol-ecule is almost planar (r.m.s. deviation = 0.0062?Å). In the crystal, the components are connected through O?I halogen bonds [3.017?(11)?Å], leading to the formation of wavelike chains along the a axis. The crystal packing also features C-H?F inter-actions.

[5,11,17,23-Tetra-tert-butyl-25,27-(3,6-dioxaoctan-1,8-di-oxy)-26,28-bis-(pyridin-2-ylmeth-oxy)calix[4]arene]sodium iodide-1,2,4,5-tetra-fluoro-3,6-diiodo-benzene-methanol (2/3/4).

Project description:The title compound, [Na(C62H76N2O6)]I·1.5C6F4I2·2CH3OH, is composed of five components: a calix[4]arene derivative (hereinafter C4), a sodium cation, an iodide anion, a 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene (tFdIB) mol-ecule and a methanol mol-ecule in a 1:1:1:1.5:2 ratio. The complex shows several inter-esting features: (i) the polyoxygenated loop of C4 effectively chelates a sodium cation in the form of a distorted octahedron and separates it from the iodide counter-ion, the shortest Na(+)?I(-) distance being greater than 6.5?Å; (ii) the cavity of C4 is filled by a methanol mol-ecule; (iii) a second methanol mol-ecule is hydrogen-bonded to the N atom of a pyridinyl substituent pendant of C4 and halogen-bonded to the I atom of a tFdIB mol-ecule; (iv) the two I atoms of another tFdIB mol-ecule are halogen-bonded to two iodide anions, which act as monodentate halogen-bond acceptorss; (v) one of the two tFdIB molecules is located about a centre of inversion.

3,6-Dimethyl-N,N-bis-(pyridin-2-yl)-1,2,4,5-tetra-zine-1,4-dicarboxamide.

Project description:In the title mol-ecule, C(16)H(16)N(8)O(2), four atoms of the tetra-zine ring are coplanar, with the largest deviation from the plane being 0.0236?(12)?Å; the other two atoms of the tetra-zine ring deviate on the same side from this plane by 0.320?(4) and 0.335?(4)?Å. Therefore, the central tetra-zine ring exhibits a boat conformation. The dihedral angles between the mean plane of the four coplanar atoms of the tetrazine ring and the two pyridine rings are 26.22?(10) and 6.97?(5)°. The two pyridine rings form a dihedral angle of 31.27?(8)°. In the molecule, there are a number of short C-H?O interactions. In the crystal, molecules are linked via a C-H?O interaction to form zigzag chains propagating along the [010] direction.

6-[6-(Pyridin-2-yl)-1,2,4,5-tetra-zin-3-yl]pyridin-3-amine monohydrate.

Project description:The packing of the title compound, C12H9N7·H2O, is dominated by hydrogen bonding and π-stacking. Layers parallel to [010] are established by hydrogen bonds involving all amine donor functions and one of the water donor functions, while the remaining water donor function enables the stacking of the layers along [10-1], which is accompanied by π-stacking. In the molecule, the plane of the central tetra-zine ring forms angles of 5.33 (7) and 19.84 (8)° with the adjacent 3-amine-pyridine and pyridine rings, respectively.

Methyl 4-[5-(4-fluoro-phen-yl)-4-(pyridin-4-yl)-1H-imidazol-2-ylsulfan-yl]butanoate.

Project description:The title compound, C(19)H(18)FN(3)O(2)S, was synthesized in the course of studies on 2-alkyl-sufanylimidazoles as p38 mitogen-activated protein kinase inhibitors. The synthesis was achieved by nucleophilic substitution of 4-(4-fluoro-phen-yl)-5-(pyridin-4-yl)-1,3-dihydro-imidazole-2-thione with methyl 4-bromo-butanoate. The five-membered heterocycle makes dihedral angles of 32.4?(2) and 18.3?(2)° with the fluoro-phenyl and pyridinyl rings, respectively, indicating a low degree of conjugation between these rings. Intra-molecular C-H?N and inter-molecular N-H?N hydrogen bonds as well as C-H?? inter-actions seem to be effective in stabilization of the crystal structure.
