Ligand formation

Postby Ryan Cerny 3I » Mon Nov 07, 2016 10:23 am

Is it vital that we know how to determine how many ligands a TM cation can form? Is there even a way to deduce this?

Ligands are defined as Lewis bases attached to the central metal atom or ion in a d-metal complex (a complex being a species consisting of a central metal atom or ion to which a number of molecules or ions are attached by coordinate covalent bonds). Ligands can be either ions or molecules and they usually have one or more lone pairs of electrons which it uses to bond to a central atom or ion; they are directly attached to the central atom. Based on what the TM ion is, its number of ligands will vary; you can use a general Lewis structure to determine what the most stable arrangement would be.
