Polymorphs of 1,1-bis(4-hydroxyphenyl)cyclohexane and multiple Z′ crystal structures by melt and sublimation crystallization

Abstract

Close packing conflict in a metastable polymorph of the pure title host (Z′ = 2, melt crystal 1m) is resolved in the stable form (Z′ = 1, sublimed crystal 1s) as O–H⋯O hydrogen bond changes to O–H⋯π interaction. Melt crystallization and sublimation show a greater percentage of high Z′ structures in CSD statistics.
