A 1:2 crystalline solvate (1) of 5-methylbenzene-1,3-dicarbaldehyde bis-(p-tolylsulphonylhydrazone) (2) and benzene has been synthesized and characterized as a channel inclusion complex by X-ray analysis.Crystals of (1) are orthorhombic, with a=8.135(2), b=19.021(4), c=23.015(2) Angstroem, Z=4, and space group C2ca (No. 41).The structure was solved by direct methods and refined to R 0.039 on 1 211 observed diffractometer data.The bis-(tosylhydrazone) molecules (2) attain crystallographic two-fold symmetry and constitute the host lattice.The guest (benzene) molecules occupy positions in continuous, zigzag channels running through the crystal along the a direction, the axis of each channel coinciding with a crystallographic two-fold screw axis.
