The co-crystal 4,6-di-acetyl-resorcinol-1-amino-pyrene (2/1).

The structure of the title mol-ecular complex, CHN·2CHO, at 150 K has been determined. The mol-ecules form stacks consisting of aggregates with disordered 1-amino-pyrene mol-ecule surrounded by two 4,6-di-acetyl-resorcinol mol-ecules. Neighbouring stacks are linked by hydrogen bonds between the amine H atoms of the 1-amino-pyrene mol-ecule with the adjacent carbonyl oxygen atom of the 4,6-di-acetyl-resorcinol mol-ecule.
