  2. Sulfur hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_hexafluoride

    6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. [citation needed] Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents.

  3. Octahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Octahedral_molecular_geometry

    When an anionic ligand replaces a coordinated water molecule the reaction is called an anation. The reverse reaction, water replacing an anionic ligand, is called aquation. For example, the [CoCl(NH 3) 5] 2+ slowly yields [Co(NH 3) 5 (H 2 O)] 3+ in water, especially in the presence of acid or base. Addition of concentrated HCl converts the aquo ...

    An LCAO in, for example, sulfur hexafluoride, taking a basis set of the one sulfur 3s-orbital, the three sulfur 3p-orbitals, and six octahedral geometry symmetry-adapted linear combinations (SALCs) of fluorine orbitals, a total of ten molecular orbitals are obtained (four fully occupied bonding MOs of the lowest energy, two fully occupied ...

    In effect, they considered nitrogen dioxide as an AX 2 E 0.5 molecule, with a geometry intermediate between NO + 2 and NO − 2. Similarly, chlorine dioxide (ClO 2) is an AX 2 E 1.5 molecule, with a geometry intermediate between ClO + 2 and ClO − 2. [citation needed] Finally, the methyl radical (CH 3) is predicted to be trigonal pyramidal ...

  6. Chemical structure - Wikipedia

    en.wikipedia.org/wiki/Chemical_structure

    Its determination includes a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together and can be represented using structural ...

  7. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.

  8. Square planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Square_planar_molecular...

    Structure of cisplatin, an example of a molecule with the square planar coordination geometry. In chemistry, the square planar molecular geometry describes the stereochemistry (spatial arrangement of atoms) that is adopted by certain chemical compounds. As the name suggests, molecules of this geometry have their atoms positioned at the corners.

  9. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.
