title: 5-Oxatricyclo[5.1.0.0(1,3)]octan-4-one, containing an enantiomorph and a racemate and not two polymorphs, is another example of a composite crystal.
abstract: This new example of a composite crystal adds to the small number previously reported among inorganic and molecular materials. Revision of the nomenclature used allows more fruitful comparison with the precedents.
