  2. Germanium tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Germanium_tetrafluoride

    Germanium tetrafluoride is a noncombustible, strongly fuming gas with a garlic-like odor. It reacts with water to form hydrofluoric acid and germanium dioxide. Decomposition occurs above 1000 °C. [5] Reaction of GeF 4 with fluoride sources produces GeF 5 − anions with octahedral coordination around Ge atom due to polymerization. [6]

  3. Xenon tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Xenon_tetrafluoride

    Xenon tetrafluoride is a colorless crystalline solid that sublimes at 117 °C. Its structure was determined by both NMR spectroscopy and X-ray crystallography in 1963. [ 6 ] [ 7 ] The structure is square planar , as has been confirmed by neutron diffraction studies. [ 8 ]

  4. Germanium difluoride - Wikipedia

    en.wikipedia.org/wiki/Germanium_difluoride

    Germanium difluoride forms orthorhombic crystals with a space group P2 1 2 1 2 1 (No. 19), Pearson symbol oP12, and lattice constants a = 0.4682 nm, b = 0.5178 nm, c = 0.8312 nm, Z = 4 (four structure units per unit cell). Its crystal structure is characterized by strong polymeric chains composed by GeF 3 pyramids.

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

    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 ...
