In the title compound, C(16)H(12)FIO(2)S, the 4-fluoro-phenyl ring is rotated slightly out of the benzofuran plane, as indicated by the dihedral angle of 4.48 (5)°. In the crystal structure, pairs of I⋯O halogen bonds [I⋯O = 3.123 (1) Å] link the mol-ecules into centrosymmetric dimers. These dimers are further linked via aromatic π-π inter-actions between the benzene and 4-fluoro-phenyl rings o...

In the title compound, C(15)H(10)BrClO(2)S, the 4-bromo-phenyl ring makes a dihedral angle of 86.85 (6)° with the mean plane [mean deviation = 0.009 (2) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by slipped π-π inter-actions between the benzene and the furan rings of adjacent mol-ecules [centroid-centroid distance = 3.884 (2), inter-planar distance = 3.369 (2) and slip...

A slight modification of the synthetic procedure resulted in a new (Cc) polymorph vinylic tellurium-trichloride Z-Cl(Ph)C=C(Ph)TeCl3 (1, β-form) which is stabilized by Te⋯Cl chalcogen bonds, assembling its molecules into zigzag chains. Such packing motive contrast to known (Pca21) α-form, CCDC refcode: BESHOW), built upon Te⋯π(Ph) bonded We noted similar case [Te⋯halogen] vs. [Te⋯π(Ph)] supramo...

The title compound, C10H4I2O3, is an iodinated 3-formyl-chromone derivative, and the atoms are essentially coplanar [r.m.s. deviation = 0.049 Å, largest deviation from the least-squares plane = 0.111 (9) Å for the CH(=O) C atom]. In the crystal, mol-ecules are linked into a three-dimensional network through halogen bonds [I⋯O = 3.352 (5) and 3.405 (7) Å, C-I⋯O = 144.2 (3) and 154.5 (3)°, and C=...

In the title compound, C10H5BrO3, a brominated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0420 Å), with the largest deviation from its mean plane [0.109 (2) Å] being found for the ring-bound carbonyl O atom. In the crystal, mol-ecules are linked through halogen bonds [Br⋯O = 3.191 (2) Å, C-Br⋯O = 167.32 (10)° and C=O⋯Br = 168.4 (2)°] along [101]...

In the title compound, C14H10Br2O4, the dihedral angle between the aromatic rings is 67.29 (19)°. Both meth-oxy-group C atoms lie close to the plane of their attached ring [deviations = -0.130 (4) and 0.005 (5) Å]. In the crystal, mol-ecules pack in a centrosymmetric fashion and inter-act via a mixture of weak π-π stacking inter-actions [centroid-centoid separations = 4.044 (2) and 4.063 (3) Å]...

UV-Vis measurements showed that the interaction of pseudohalide anions, A(-) (A(-) = N3(-), NCO(-), NCS(-)), with electrophilic bromocarbons, R-Br (R-Br = CBr4, CBr3NO2, CBr3CONH2, CBr3H, CBr3F, CBr3CN or C3Br2F6), in solution results in formation of [R-Br, A(-)] complexes. These associates are characterized by intense absorption bands in the 200-350 nm range showing distinct Mulliken correlati...

The title compound, C(10)H(6)ClNO(2), has a dihedral angle of 46.46 (5)° between the benzene and maleimide rings. A short inter-molecular halogen-oxygen contact is observed, with a Cl⋯O distance of 3.0966 (13) Å. Both CO groups are involved in two C-H⋯O inter-actions, which gives rise to sheets parallel to (100). In addition, these sheets exhibit a π-π stacking inter-action between the benzene ...

The mol-ecular and crystal structures of the title compound, C(23)H(28)Cl(2)N(2)O(2), are very close to those of the bromine-substituted analogue N,N-dicyclo-hexyl-2-(5,7-dibromo-8-quinol-yloxy)acetamide. The two cyclo-hexyl groups adopt normal chair conformation. The amide N and C atoms have a planar configuration. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds and a...

In the title compound, C10H5IO3, an iodinated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0259 Å), with the largest deviation from the least-squares plane [0.056 (5) Å] being found for the formyl O atom. In the crystal, mol-ecules are linked through I⋯O halogen bonds [I⋯O = 3.245 (4) Å, C-I⋯O = 165.95 (13) and C=O⋯I = 169.7 (4)°] along [101]. The...
