文摘
Methanol forms a cocrystal with acetylene, of which single crystals were grown in situ. The methanol chains of the β-methanol are retained, and acetylene is intercalated between the layers. The weight ratio of host to guest is 1.23, the lowest and most efficient value for all known acetylene cocrystals. Further, the first single crystal structure for the low-temperature α-form of methanol is reported confirming previous neutron powder data. For the β-form of methanol, the space group Cmc21 is favored in contrast to former data in Cmcm.
