  2. Potassium tetracyanonickelate - Wikipedia

    en.wikipedia.org/wiki/Potassium_tetracyanonickelate

    The salt consists of potassium ions and the tetracyanonickelate coordination complex, which is square planar. The [Ni(CN) 4 ] 2- anions are arranged in a columnar structure with Ni---Ni distances of 4.294 Å, which is well beyond the sum of the van der Waals radius of the nickel cation. [ 1 ]

  3. Pentagonal planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Pentagonal_planar...

    The only two pentagonal planar species known are the isoelectronic (nine valence electrons) ions [XeF 5] − (pentafluoroxenate(IV)) and [IF 5] 2− (pentafluoroiodate(III)). [1] Both are derived from the pentagonal bipyramid with two lone pairs occupying the apical positions and the five fluorine atoms all equatorial.

  4. Pentagonal bipyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Pentagonal_bipyramidal...

    [2] [3] [page needed] Pentagonal bipyramids are claimed to be promising coordination geometries for lanthanide -based single-molecule magnets , since they present no extradiagonal crystal field terms, therefore minimising spin mixing, and all of their diagonal terms are in first approximation protected from low-energy vibrations, minimising ...

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl. This reaction can be used to remove potassium hexacyanidoferrate(II) from a solution. [citation needed] A famous reaction involves treatment with ferric salts, most commonly Iron(III) chloride, to give Prussian blue. In the reaction with Iron(III) chloride, producing Potassium chloride as a ...

  6. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Trigonal planar: Molecules with the trigonal planar shape are somewhat triangular and in one plane (flat). Consequently, the bond angles are set at 120°. For example, boron trifluoride. Angular: Angular molecules (also called bent or V-shaped) have a non-linear shape. For example, water (H 2 O), which has an angle of about 105°. A water ...

    where: β > α are the two greatest valence angles of coordination center; θ = cos −1 (− 1 ⁄ 3) ≈ 109.5° is a tetrahedral angle. Extreme values of τ 4 and τ 4 ′ denote exactly the same geometries, however τ 4 ′ is always less or equal to τ 4 so the deviation from ideal tetrahedral geometry is more visible.

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    Nomenclature of Inorganic Chemistry, IUPAC Recommendations 2005 is the 2005 version of Nomenclature of Inorganic Chemistry (which is informally called the Red Book). It is a collection of rules for naming inorganic compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC).

  9. Complete graph - Wikipedia

    en.wikipedia.org/wiki/Complete_graph

    Geometrically K 3 forms the edge set of a triangle, K 4 a tetrahedron, etc. The Császár polyhedron, a nonconvex polyhedron with the topology of a torus, has the complete graph K 7 as its skeleton. [15] Every neighborly polytope in four or more dimensions also has a complete skeleton. K 1 through K 4 are all planar graphs.
