species interchangeably. The robust association manifests in packing equivalence in all of the inclusioncompounds of TP2 with the exception of the compound formed with pyridine and o-dichlorobenzene guests; in the latter, pyridine terminates the otherwise 3-dimensional hydrogen-bonded organization. The half-component of TP2, i.e., 4,6-bis(4-hydroxyphenyl)-m-xylene (BX), deduced by simple structural
