Crystal and molecular structure of cyclo{quater[(5-t-butyl-2-hydroxy-1,3-phenylene)methylene]} toluene (1 : 1) clathrate

Abstract

Single-crystal X-ray analysis has shown the tetrameric structure of the low melting point product obtained from the base catalysed condensation of formaldehyde and para-t-butylphenol and its ability to form a stable cage-type clathrate with toluene.
