Coordination #

[105194078]

Can someone explain to me how to determine how many coordination numbers a molecule has? I'm currently doing some homework and need some clarification.

[Zoya Mulji 1K]

coordination # is the # of ligand molecules attached to the transition metal ion.

[Sydney Jacobs 1C]

Coordination number refers to the number of points to which ligands are attached to the central atom. For example, in [NiCl4]2-, the nickel is attached to 4 Cl- ligands, so the coordination number is 4.

so if there's only one molecule attached, but it's attached at 2 sites (chelating and bidentate) you would count the coordination number as 2?

The coordination number is the number of Ligands attached to the central transition metal

In question 9C.9 from the homework, why are the coordination numbers from part C and D 6?

[Chetas Holagunda 3H]

Think of it as how many Ligands are attached to the central metal cation. Each of those bonds added up equals the coordination number.
