Cocrystallization with Acetylene: Molecular Complexes with Acetone and Dimethyl Sulfoxide

Different phases: Molecular complexes of acetylene and acetone or DMSO are formed simultaneously in different phases. Crystalline acetylene:actone 1:2 (A) and 1:1 (B), as well as acetylene:DMSO 2:1 (C) complexes have been obtained by in situ cocrystallization under pressure in a capillary with the u...

Description
Summary:Different phases: Molecular complexes of acetylene and acetone or DMSO are formed simultaneously in different phases. Crystalline acetylene:actone 1:2 (A) and 1:1 (B), as well as acetylene:DMSO 2:1 (C) complexes have been obtained by in situ cocrystallization under pressure in a capillary with the use of an IR laser. The crystal structures may be interpreted as a “frozen” situation of the liquids.
