Specific entrapment of methanol and dimethyl sulphoxide (DMSO) by a simple host compound (triphenylmethanol). Crystal structures of the Ph3COH·MeOH (1 : 1) and Ph3COH·DMSO (2 : 1) clathrate inclusion complexes
Abstract
Triphenylmethanol (1) is shown to be a specific clathrate host for methanol and dimethyl sulphoxide; host–guest interaction schemes in the two crystalline inclusion complexes are discussed.
