ABSTRACT
At room temperature trans-9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylic acid forms different clathrates with ethyl and butyl acetate in a 1:1 host-guest ratio. Increasing the formation temperature up to 40°C gives rise to pseudodimorphic clathrates with half the content of the guest component. All the clathrates studied feature intersecting channels of guest molecules within their structures.
