[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

Tungsten(IV) chloride, WCl 4, a black solid, which adopts a polymeric structure. Tungsten(V) chloride WCl 5, a black solid which adopts a dimeric structure. Tungsten(VI) chloride WCl 6, which contrasts with the instability of MoCl 6. Organotungsten compounds are numerous and also span a range of oxidation states.
Gilbert Newton Lewis ForMemRS [1] (October 23 [2] [3] [4] or October 25, 1875 – March 23, 1946) [1] [5] [6] was an American physical chemist and a dean of the college of chemistry at University of California, Berkeley.
The dot-and-cross diagram of the LDQ structure of the ground state of acetylene is shown on the left and that of the first excited state of acetylene is shown on the right. The nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins.
At room temperature, tungsten hexafluoride is a gas. ... Lewis dot diagram structures show three formal alternatives for describing bonding in boron monofluoride.
2), a MO diagram may show one of the identical bonds to the central atom. For other polyatomic molecules, an MO diagram may show one or more bonds of interest in the molecules, leaving others out for simplicity. Often even for simple molecules, AO and MO levels of inner orbitals and their electrons may be omitted from a diagram for simplicity.
Chromium(II) acetate, Cr 2 (μ-O 2 CCH 3) 4 (H 2 O) 2, was the first chemical compound containing a quadruple bond to be synthesized. It was described in 1844 by E. Peligot, although its distinctive bonding was not recognized for more than a century.
