Coordination Number

Postby salvadorramos3k » Sun Dec 01, 2019 12:42 am

How do you determine coordination numbers? I know it should say through the ligand, but what if we aren't given a ligand? For example, how do we know that Cu+ can have a coordination number of 2 or 4?

The coordination number of an atom in a molecule is the number of atoms bonded to the atom. For Cu+, it would simply be the possible amount of atoms that it could bond to.

The coordination number represents the number of bonds the central atom has in a molecule. In regards to Cu+, the coord # would be determined by the possible # of atoms it can bind to, and the problem will usually tell you if it has a +2, +4 charge
