  2. Xenon difluoride - Wikipedia

    en.wikipedia.org/wiki/Xenon_difluoride

    Xenon difluoride is a linear molecule with an Xe–F bond length of 197.73 ± 0.15 pm in the vapor stage, and 200 pm in the solid phase. The packing arrangement in solid XeF 2 shows that the fluorine atoms of neighbouring molecules avoid the equatorial region of each XeF

  3. Three-center four-electron bond - Wikipedia

    en.wikipedia.org/.../Three-center_four-electron_bond

    This bonding scheme is succinctly summarized by the following two resonance structures: I—I···I − ↔ I − ···I—I (where "—" represents a single bond and "···" represents a "dummy bond" with formal bond order 0 whose purpose is only to indicate connectivity), which when averaged reproduces the I—I bond order of 0.5 obtained ...

  4. Xenon compounds - Wikipedia

    en.wikipedia.org/wiki/Xenon_compounds

    In addition to compounds where xenon forms a chemical bond, xenon can form clathrates—substances where xenon atoms or pairs are trapped by the crystalline lattice of another compound. One example is xenon hydrate (Xe· 5 + 3 ⁄ 4 H 2 O), where xenon atoms occupy vacancies in a lattice of water molecules. [ 32 ]

  5. Bond order - Wikipedia

    en.wikipedia.org/wiki/Bond_order

    The bond order itself is the number of electron pairs (covalent bonds) between two atoms. [3] For example, in diatomic nitrogen N≡N, the bond order between the two nitrogen atoms is 3 (triple bond). In acetylene H–C≡C–H, the bond order between the two carbon atoms is also 3, and the C–H bond order is 1 (single bond).

  6. Molecular orbital theory - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_theory

    Bond order is the number of chemical bonds between a pair of atoms. The bond order of a molecule can be calculated by subtracting the number of electrons in anti-bonding orbitals from the number of bonding orbitals, and the resulting number is then divided by two. A molecule is expected to be stable if it has bond order larger than zero.

  7. Chemical table file - Wikipedia

    en.wikipedia.org/wiki/Chemical_table_file

    Chemical table file (CT file) is a family of text-based chemical file formats that describe molecules and chemical reactions. One format, for example, lists each atom in a molecule, the x-y-z coordinates of that atom, and the bonds among the atoms.

  8. Xenon oxydifluoride - Wikipedia

    en.wikipedia.org/wiki/Xenon_oxydifluoride

    Xenon oxydifluoride is an inorganic compound with the molecular formula XeOF 2.The first definitive isolation of the compound was published on 3 March 2007, producing it by the previously-examined route of partial hydrolysis of xenon tetrafluoride.

  9. Xenon tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Xenon_tetrafluoride

    Xenon tetrafluoride is a chemical compound with chemical formula XeF 4. It was the first discovered binary compound of a noble gas. [3] It is produced by the chemical reaction of xenon with fluorine: [4] [5] Xe + 2 F 2 → XeF 4. This reaction is exothermic, releasing an energy of 251 kJ/mol. [3]
