Coordination number

Postby JustinHorriat_4f » Sun Nov 24, 2019 3:50 pm

I am a bit confused on what determines coordination compound. Can anyone give me an example and explain. Thank you!

A coordination compound is formed when a ligand (a molecule or ion) forms coordinate covalent bonds with the central atom which is usually a transition metal. The coordination number of the coordination compound is determined by the number of bonds the central atom forms with the ligands. For example, in [Fe(CN)6]^-4 the central atom is Fe which is a transition metal and the ligands are CN-. The coordination number of this compound is 6 because the Fe forms 6 coordinate covalent bonds with the 6 CN-.

do coordination numbers also depends on the size of the coordination compound?

Coordination numbers depend on the number of bonds.

The coordination number is determined by the bonds to the central atom.

how do you calculate coordination number of complexes?

can a ligand be attached to a nonmetal?

Do the ligands only attach to transition metals? Why not an element that is not a transition metal?
