چکیده

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⋯π(pyrid-yl) inter-actions.

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 i...

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 a...

1,2,4,5-Tetra­fluoro-3,6-diiodo­benzene–2,3-bis­(pyridin-2-yl)pyrazine (1/1)

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...

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 copl...

The title compound, [Cu(NCS)(C(12)H(8)N(6))](n), is a self-assembled two-dimensional metal-organic network. The Cu atom is linked by two N atoms from two 3,6-di-4-pyridyl-1,2,4,5-tetra-zine ligands and by the N and S atoms from two thio-cyanate ligands in a distorted tetra-hedral environment. The Cu atom and the thio-cyanate ligand occupy a crystallographic mirror plane m, and a crystallographi...
