Crystal asymmetric unit
Webadvances in experimental polymorph searching and crystal en-gineering highlight the rich variety of multi-component crys-tals (co-crystals, salts, solvates, etc) as well as crystal structures with multiple molecules in the asymmetric unit. For instance, many well-studied molecules, including aspirin [23], resorcinol WebZ' is the number of asymmetric units. This is Z divided by the lowest multiplicty in your list of Wyckoff positions. Sometimes, the formula unit is easy to see, as in salts or molecular...
