  2. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    Sulfur tetrafluoride has a steric number of 5. The steric number of a central atom in a molecule is the number of atoms bonded to that central atom, called its coordination number, plus the number of lone pairs of valence electrons on the central atom. [11] In the molecule SF 4, for example, the central sulfur atom has four ligands; the ...

  4. Seesaw molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Seesaw_molecular_geometry

    The seesaw geometry occurs when a molecule has a steric number of 5, with the central atom being bonded to 4 other atoms and 1 lone pair (AX 4 E 1 in AXE notation). An atom bonded to 5 other atoms (and no lone pairs) forms a trigonal bipyramid with two axial and three equatorial positions, but in the seesaw geometry one of the atoms is replaced ...

    Germanium disulfide or Germanium(IV) sulfide is the inorganic compound with the formula Ge S 2. It is a white high-melting crystalline solid. [1] [2] The compound is a 3-dimensional polymer, [3] [4] in contrast to silicon disulfide, which is a one-dimensional polymer. The Ge-S distance is 2.19 Å. [3]

  6. Sulfur hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_hexafluoride

    Sulfur hexafluoride or sulphur hexafluoride (British spelling) is an inorganic compound with the formula SF 6. It is a colorless, odorless, non-flammable, and non-toxic gas. SF 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 ...

  7. Sulfoxide - Wikipedia

    en.wikipedia.org/wiki/Sulfoxide

    A lone pair of electrons resides on the sulfur atom, giving it tetrahedral electron-pair geometry and trigonal pyramidal shape (steric number 4 with one lone pair; see VSEPR theory). When the two organic residues are dissimilar, the sulfur atom is a chiral center, for example, in methyl phenyl sulfoxide.

  8. Cyclic compound - Wikipedia

    en.wikipedia.org/wiki/Cyclic_compound

    Because of the tremendous diversity allowed, in combination, by the valences of common atoms and their ability to form rings, the number of possible cyclic structures, even of small size (e.g., < 17 total atoms) numbers in the many billions. Cyclic compound examples: All-carbon (carbocyclic) and more complex natural cyclic compounds

  9. Thionyl tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Thionyl_tetrafluoride

    Thionyl tetrafluoride, also known as sulfur tetrafluoride oxide, is an inorganic compound with the formula S O F 4. It is a colorless gas. The shape of the molecule is a distorted trigonal bipyramid, with the oxygen found on the equator. The atoms on the equator have shorter bond lengths than the fluorine atoms on the axis.
