An isodesmic crystal is a crystal in which all the bonds have the same electrostatic valency.{{cite book|last1=Pfennig|first1=Brian|title=Principles of Inorganic Chemistry|date=30 March 2015|url=https://books.google.com/books?id=-twqBwAAQBAJ|publisher=John Wiley & Sons|isbn=9781118859100|accessdate=3 May 2016}} This means that all the bonds are of the same strength. Diamonds and halite have isodesmic crystals. The opposite of an isodesmic crystal is an anisodesmic crystal, in which anions more strongly bonded to central coordinating cation. Graphite is an example of an anisodesmic crystal.
