A novel transformation of a 1 : 1 : 1 racemic complex of 2,2′-dihydroxy-1,1′-binaphthyl, Me 4 N + Cl − and MeOH into a conglomerate in the solid state by heating or contact with MeOH vapour

The title racemate-to-conglomerate transformation which occurs in the solid state on heating or contact with MeOH vapour has been studied by IR and DTA spectral measurements, microscopic observation, and by X-ray structural and X-ray powder diffraction analysis.
