Research and draw (on paper) the isomers of another coordination compound that has octahedral geometry.

Sulfur hexafluoride SF6

Explanation:

In chemistry, the shape of the compounds in which six ligands (atoms, molecules or ions) are arranged around a central atom or ion, defining the vertices of an octahedron, is called octahedral molecular geometry or Oh. It is a very common structure, and it is very studied for its importance in the coordination chemistry of transition metals. From it, other important molecular geometries are derived by continuous deformation, such as the elongated octahedron, the flat octahedron, the square-based pyramid and the flat square. Indirectly, it is also related to tetrahedral molecular geometry.

The concept of octahedral coordination geometry was developed by Alfred Werner to explain the stoichiometry and isomeries in the coordination compounds. An example of a strictly octahedral compound is SF6 sulfur hexafluoride, but chemists use the term in a lax form, so that it is applied to compounds that are not mathematically octahedra, such as cobalt hexaamine (III).

Isomers are molecules that have the same molecular formula but different structure. It is classified as structural isomers and stereoisomers. Structural isomers differ in the way of joining their atoms and are classified into chain, position and function isomers.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
