Abstract The inclusion complex ofp-tert-butylcalix[5]arene with tetralin has been characterized in the solid state by a single crystal X-ray diffraction study and by13C CP/MAS NMR experiments. A crystallographic mirror plane bisects the calix[5]arene and contains the tetralin molecule (which is dynamically disordered). The guest penetrates the upper rim of the calixarene and the experimental results indicate the saturated ring is imbedded most deeply.p-tert-Butylcalix[5]arene (tetralin) · 2 EtOH belongs to the monoclinic space group C2/m witha = 22.187(6),b = 15.823(6),c = 18.168(5) Å,β = 99.70(2)°, andD c = 1.09 g cm−3 forZ = 4. Refinement based on 1652 observed reflections led to a finalR value of 0.081.
