✦ Synopsis
A new kind of host compound, 2,5-bis(diphenylmethyl)hydroquinone is designed and prepared. The crystal structure of the inclusion compound formed by the host with benzaldehyde was determined by single crystal X-ray diffraction. The result shows that the host exhibits a stable conformation through intramolecular CH/p interactions in the inclusion crystal, and benzaldehyde guest molecules are accommodated in the channel which is constructed by the hosts, in which intermolecular C-H/p interactions between the hosts, play an important role in the architecture of channel framework besides van der Waal's forces. The complex structure is further stabilized by strong hydrogen bonding (O1-H1/O1 0 ) and two weak C-H/O interactions (C5 0 -H5 0 /O1, C3-H3/O1 0 ) between the host and guest.
