Crystal structure, Hirshfeld surface and inter-molecular inter-action energy analysis of the halogen-bonded 1:1
1Chemistry and Biochemistry Department Missouri State University,Springfield MO 65897 USA.
Abstract:
The structure of the 1:1 cocrystal formed between 1-bromo-3,5-di-nitro-benzene and N,N-di-methyl-pyridin-4-amine that features a C-Br⋯N halogen bond is reported. The cocrystal, C6H3BrN2O4·C7H10N2, crystalizes in the monoclinic space group P21/c with Z = 4. Hirshfeld surface analysis and inter-molecular inter-action energies within the cocrystal structure are reported.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
