Pauling's Rules Flashcards
Coordination number
The number of Anions packed in next to a cation. Determined by the ratio fo their radiuses.

Coordination Number
Anisodesmic structure
Some of the bonds between atoms will take up more than half the charge.
Some of the bonds between atoms will take up more than half the charge.
Anisodesmic structure
Isodesmic bond
ionic bonds are all equaly shared. (CN/Charge=1)

Isodesmic bond
Mesodesmic
The structure contains multiple polyhedra, which are both isodesmic and anisodesmic

Pauling’s rules 3-4
The cations want to be as far appart as possible. as such, anions share corners of the polyhedra.
